The first holding portion is provided on the housing, while the second holding portion is provided on the mounting member. When the mounting member is mounted on the housing, the second sandwiching portion is arranged to face the first sandwiching portion in the direction of the rotation axis of the fan, and is configured to sandwich the clothing cloth between the second sandwiching portion and the first sandwiching portion. ing.

The locking mechanism is configured to regulate the movement of the mounting member with respect to the housing in the rotation axis direction by locking the mounting member with respect to the housing in the rotation axis direction of the fan. The locking mechanism includes a first locking portion provided on one of the housing and the mounting member and a second locking portion provided on the other of the housing and the mounting member. The second locking portion is configured to lock the first locking portion in the rotation axis direction at any one of a plurality of locking positions different from each other in the rotation axis direction of the fan. Each of the plurality of locking positions is on a path through which the first locking portion can pass in the process of mounting the mounting member on the housing along the motion line.

It should be noted that the "plurality of locking positions different from each other in the direction of the rotation axis" here means that they are at different positions on the same straight line extending in the direction of the rotation axis and that they intersect the rotation axis also in the direction of the rotation axis. It may include the case where the position is different in the direction. Further, "locking in the rotation axis direction" includes a case where the lock is made in only one predetermined direction of the extension direction of the rotation axis and a case where the lock is made in both directions in the extension direction of the rotation axis. sell. At least, it is preferable that the mounting member and the housing are locked in a direction away from each other.

The connector 37 is arranged so that the connector 973 of the cable 97 can be inserted and removed in the direction orthogonal to the rotation axis A1 (in the radial direction of the main body 3).

Further, the housing 4 is provided with a regulating rib 381 configured to restrict the connector 973 from moving outward in the radial direction (in other words, in the direction in which the connector 973 is detached from the connector 37). The regulation rib 381 is a rib (wall portion) provided on the outer side in the radial direction with respect to the connector arrangement area 38 and configured to be in contact with the connector 973 arranged in the connector arrangement area 38. The regulating rib 381 can prevent the connector 973 from coming off from the connector 37 by abutting the connector 973 from the outside in the radial direction. As a result, if the user moves while wearing the jacket 9 to which the blower 1 is attached and the cable 97 is moved, the cable 97 may be disconnected from the blower 1. Can be reduced. The state in which the connector 973 is connected to the connector 37 is shown in FIGS. 16 and 17 corresponding to the modified examples described later.

Hereinafter, the ring member 5 will be described with reference to FIGS. 3 and 4. As shown in FIG. 4, the ring member 5 includes an outer tubular portion 51, the above-mentioned front flange 53, and a finger hook protrusion 55. In this embodiment, the outer cylinder portion 51, the front flange 53, and the finger hook protrusion 55 are integrally formed of resin. In the present embodiment, the ring member 5 is made of a resin having a color different from that of the housing 4. Specifically, a color having a clear contrast is adopted, and the ring member 5 is formed substantially entirely in green, while the housing 4 is formed substantially entirely in white.

The outer tubular portion 51 is a portion that is externally fitted to the inner tubular portion 41 of the housing 4. Therefore, the outer cylinder portion 51 is formed as a short cylindrical body having an inner diameter substantially the same as the outer diameter of the inner cylinder portion 41 of the housing 4.

As described above, the front flange 53 faces the rear flange 43 of the housing 4 in the front-rear direction (rotational axis A1 direction), and the fan mounting portion 93 of the mounting opening 91 of the jacket 9 and the rear flange 43. It is a part that sandwiches. The front flange 53 is provided so as to project radially outward from one end (specifically, the rear end) of the outer cylinder 51 in the central axis A2 direction. In the present embodiment, the outer diameter of the front flange 53 is set to be substantially the same as the outer diameter of the rear flange 43 of the housing 4.

The finger hook protrusion 55 is a protrusion for facilitating the user to hang a finger to grip the ring member 5, rotate the ring member 5 around the central axis A2, or hold the ring member 5 so as not to rotate. In the present embodiment, the finger hook projection 55 is formed in a substantially triangular plate shape, its two sides are connected to the outer peripheral surface of the outer tubular portion 51 and the front surface of the rear flange 53, and the plate surface is in the circumferential direction of the central axis A2. It is provided so as to intersect with. In the present embodiment, a plurality of finger hook protrusions 55 are provided and are arranged apart from each other in the circumferential direction.

As shown in FIG. 4, the blower device 1 configured as described above further includes a locking mechanism 6, a rotation regulating mechanism 7, and an additional locking mechanism 8. The locking mechanism 6 locks the ring member 5 with respect to the housing 4 in the rotation axis A1 direction (central axis A2 direction) so as to restrict the movement of the ring member 5 with respect to the housing 4 in the rotation axis A1 direction. It is a configured mechanism. The rotation regulation mechanism 7 is a mechanism configured to regulate the rotation of the ring member 5 with respect to the housing 4 by locking the ring member 5 with respect to the housing 4 in the circumferential direction around the rotation shaft A1. In addition to the locking mechanism 6 and the rotation restricting mechanism 7, the additional locking mechanism 8 is configured to restrict the movement of the ring member 5 with respect to the housing 4 in the rotation axis A1 direction and the rotation around the rotation axis A1. Is. Hereinafter, the configurations of these mechanisms will be described in order.

First, the configuration of the locking mechanism 6 will be described with reference to FIGS. 4 to 7 and 12. In the present embodiment, the locking mechanism 6 includes a guide groove 61 provided in the inner tubular portion 41 of the housing 4, and a locking projection 66 provided in the outer tubular portion 51 of the ring member 5.

As shown in FIGS. 4 and 5, the guide groove 61 is a groove formed so as to be recessed inward in the radial direction from the outer peripheral surface of the inner tubular portion 41. The guide groove 61 is formed in a substantially L shape as a whole, and includes a first portion 611 and a second portion 614. The first portion 611 is a portion of the guide groove 61 extending from the front end (exhaust portion 46 side in the rotation shaft A1 direction) of the inner cylinder portion 41 to the rear flange 43 in the rotation shaft A1 direction. The second portion 614 is a portion of the guide groove 61 that extends continuously in the circumferential direction (specifically, in the clockwise direction D1) from the rear portion of the first portion 611. In the present embodiment, the guide groove 61 is a groove that defines a path through which the locking projection 66 (see FIG. 4) of the ring member 5, which will be described later, can pass through in the process of attaching and detaching the ring member 5 to and from the housing 4. It is configured. Specifically, in the process of attaching and detaching the ring member 5 to and from the housing 4, the locking projection 66 is inserted into the guide groove 61 and guided along the guide groove 61.

The front end of the first portion 611 constitutes a receiving port 612 that receives the locking projection 66 of the ring member 5 into the guide groove 61. The wall surface defining the front end of the second portion 614 (that is, the surface portion extending radially inward from the outer peripheral surface of the inner tubular portion 41 to the bottom of the groove) extends in the circumferential direction (specifically, in the clockwise direction D1). While present, it is slightly inclined rearward toward the rear flange 43. This wall surface is called a guide surface 615.

A first locking portion 616, which is a plane substantially orthogonal to the rotation axis A1, is formed in the intermediate portion of the guide surface 615 in the circumferential direction. In the clockwise direction D1, a step 618 slightly rearward (to the right in FIG. 5) is provided at the downstream end (lower end in FIG. 5) of the first locking portion 616. The guide surface 615 extends from the step 618 further downstream with a slight inclination.

A second locking portion 617, which is a plane substantially orthogonal to the rotation axis A1, is formed at the end portion of the guide surface 615 (that is, the end portion farthest from the first portion 611). That is, the second locking portion 617 is arranged downstream of the first locking portion 616 in the clockwise direction D1. Further, the second locking portion 617 is located at a different position with respect to the first locking portion 616 in the rotation axis A1 direction (that is, the opposite direction of the front flange 53 and the rear flange 43, the front-rear direction). More specifically, in the direction of the rotation axis A1, the second locking portion 617 is located closer to the rear flange 43 than the first locking portion 616 (more rearward). That is, the distance between the second locking portion 617 and the rear flange 43 in the direction of the rotation axis A1 is shorter than the distance between the first locking portion 616 and the rear flange 43.

As shown in FIG. 4, the locking projection 66 is provided so as to project inward in the radial direction from the inner peripheral surface of the outer tubular portion 51 of the ring member 5. In the present embodiment, the locking projection 66 is formed integrally with the outer tubular portion 51 at the rear end of the outer tubular portion 51 as a rectangular parallelepiped projection. As described above, since the locking projection 66 is guided in the guide groove 61, the locking projection 66 is set to a size that can be inserted into the guide groove 61.

As shown in FIG. 7, in the present embodiment, three guide grooves 61 are provided at three positions at equal intervals in the circumferential direction of the inner cylinder portion 41. Further, as shown in FIG. 12, three locking projections 66 are provided at three positions at equal intervals in the circumferential direction of the outer tubular portion 51.

Further, as shown in FIG. 4, the housing 4 has a first position mark 621 and a first position mark 621 at positions corresponding to the first locking portion 616 and the second locking portion 617 of the three guide grooves 61, respectively. A two-position mark 627 is attached. The first position mark 621 and the second position mark 627 are provided on the front end surface of the inner cylinder portion 41, which is a portion that is not hidden even when the ring member 5 is externally fitted to the inner cylinder portion 41. In the present embodiment, the first position mark 621 and the second position mark 627 are each configured as an equilateral triangle mark in which one of the vertices is directed outward in the radial direction. The first position mark 621 and the second position mark 627 easily recognize the positions of the first locking portion 616 and the second locking portion 617 from the front even when the ring member 5 is externally fitted to the inner cylinder portion 41. It is a mark that enables you to do it.

On the other hand, the ring member 5 has a reference protrusion mark 63 at a position corresponding to one of the three locking protrusions 66. The reference protrusion mark 63 is provided on the flange-shaped front end surface of the outer tubular portion 51, which is a portion that is not hidden even when the ring member 5 is externally fitted to the inner tubular portion 41. In the present embodiment, the reference protrusion mark 63 is configured as an equilateral triangle mark in which one of the vertices is directed inward in the radial direction. The reference protrusion mark 63 is a locking protrusion 66 from the front (that is, from a direction in which the first position mark 621 and the second position mark 627 can be seen) even when the ring member 5 is externally fitted to the inner cylinder portion 41. It is a mark that makes it easy to recognize the position.

The reference protrusion mark 63 functions as a mark for aligning the ring member 5 with respect to the housing 4 in cooperation with the first position mark 621 and the second position mark 627 described above. The first position mark 621 and the second position mark 627 are provided corresponding to only one of the three guide grooves 61, and only one of the locking protrusions 66 having the three reference protrusion marks 63 is provided. The reason why the additional locking mechanism 8 described later is provided corresponding to the above is that the additional locking mechanism 8 described later is provided at only one place in the circumferential direction. The alignment of the ring member 5 with respect to the housing 4 will be described in detail later.

Next, the configuration of the rotation regulation mechanism 7 will be described with reference to FIGS. 4, 7 and 12. In the present embodiment, the rotation regulating mechanism 7 includes a rotation locking portion 71 provided on the inner cylinder portion 41 of the housing 4, and a locking piece 75 provided on the outer cylinder portion 51 of the ring member 5.

In the present embodiment, the rotation locking portion 71 includes a first recess 711 and a second recess 716. The first recess 711 and the second recess 716 are both recesses formed so as to be recessed inward in the radial direction from the outer peripheral surface of the inner cylinder portion 41, so as to lock the locking piece 75 described later in the circumferential direction. It is configured in.

As shown in FIG. 4, the first recess 711 is provided as a recess extending forward from the rear flange 53 to the vicinity of the front end of the inner tubular portion 41. Further, as shown in FIG. 7, the first recess 711 has a V-shaped cross section orthogonal to the rotation axis A1. Of the two surfaces defining the first recess 711, the upstream surface 712 extends substantially in the radial direction in the clockwise direction D1, while the downstream surface 713 is the outer peripheral surface of the surface 712 and the inner cylinder 41. And are connected while gently tilting. The surface 712 functions as an engaging surface that engages with the claw 751 of the locking piece 75, which will be described later. Further, the surface 713 functions as a guide surface for guiding the claw 751 arranged in the first recess 711 to separate in the clockwise direction D1.

As shown in FIG. 4, the second recess 716 is provided as a side view rectangular recess in the downstream side of the first recess 711 in the clockwise direction D1 and in the substantially central portion of the inner cylinder portion 41 in the rotation axis A1 direction. It is provided. Further, as shown in FIG. 7, the second recess 716 also has a rectangular cross section orthogonal to the rotation axis A1. Of the three surfaces defining the second recess 716, the surface 717 on the most upstream side in the clockwise direction extends substantially in the radial direction and functions as an engaging surface that engages with the claw 751 of the locking piece 75. Further, as shown in FIG. 5, the front end portion of the second recess 716 is located at a position farther from the front end of the inner cylinder portion 41 than the front end portion of the first recess 711.

In the rotation axis A1 direction (front-rear direction), the distance between the front end of the first recess 711 and the front end of the second recess 716 is between the first locking portion 616 and the second locking portion 617 of the guide groove 61. Corresponds to the distance of. Further, in the clockwise direction D1, the distance between the upstream end of the first recess 711 and the upstream end of the second recess 716 is the downstream end of the first locking portion 616 of the guide groove 61 and the first. 2 Corresponds to the distance between the downstream ends of the locking portion 617.

As shown in FIGS. 4 and 5, a guide recess 73 is provided at the front end of the inner tubular portion 41 on the upstream side of the first recess 711 in the clockwise direction D1. The guide recess 73 is a recess that is shallower than the first recess 711 and the second recess 716, and is defined entirely by a curved surface so that the central portion of the front end is the deepest. The guide recess 73 receives the locking piece 75 (specifically, the claw 751) described later and guides it to the outer peripheral surface of the inner cylinder portion 41.

In the present embodiment, the guide recess 73, the first recess 711, and the second recess 716 are arranged in order from the upstream side in the clockwise direction D1. Further, with the guide recess 73, the first recess 711, and the second recess 716 as one set, three sets of the guide recess 73, the first recess 711, and the second recess 716 are placed between the above-mentioned three guide grooves 61, respectively. Have been placed.

As shown in FIG. 4, the locking piece 75 is integrally formed with the outer tubular portion 51 as a flexible strip-shaped member so as to extend in the circumferential direction of the outer tubular portion 51 of the ring member 5. ing. The locking piece 75 has an upstream end in the clockwise direction D1 connected to the outer tubular portion 51, and can be bent in the radial direction with respect to the outer tubular portion 51. As shown in FIG. 12, a claw 751 protruding inward in the radial direction is provided on the inner surface (the surface on the central axis A2 side) of the downstream end (tip) of the locking piece 75 in the clockwise direction D1. There is. The locking piece 75 is configured to be able to be locked to the first recess 711 and the second recess 716 described above via the claw 751. Further, a tab 756 projecting outward in the radial direction is provided at the tip of the locking piece 75. The tab 756 is configured so that the user can press the tab 756 in the counterclockwise direction D2 with a finger or pick it with a finger to operate it, and the first recess 711 (surface 712) of the claw 751. Alternatively, it is used to disengage the second recess 716 (surface 717).

In the circumferential direction, the distance between the locking projection 66 corresponding to the reference projection mark 63 and the claw 751 of the locking piece 75 is the guide corresponding to the first position mark 621 and the second position mark 627. It corresponds to the distance between the receiving port 612 of the groove 61 and the guide recess 73 closest to the upstream side of the guide groove 61 in the clockwise direction D1.

Hereinafter, the configuration of the additional locking mechanism 8 will be described with reference to FIGS. 4 and 10. In the present embodiment, the additional locking mechanism 8 includes a fastener 81 provided on the front side of the inner tubular portion 41 of the housing 4, and a fastener holding portion 83 provided on the outer tubular portion 51 of the ring member 5. ..

As shown in FIG. 10, the fastener 81 is configured as a metal member formed in a U shape. Both ends of the fastener 81 are supported by a rectangular parallelepiped base 811 provided on the front end surface (outer peripheral portion of the exhaust portion 46) of the inner tubular portion 41. The fastener 81 is rotatable in the rotation axis A1 direction (front-rear direction) about a rotation axis extending in the circumferential direction. More specifically, the fastener 81 is rotatable between the release position shown in FIG. 4 and the fixed position shown in FIG. At the release position, the fastener 81 is arranged radially inside the outer diameter of the inner cylinder portion 41 when viewed from the rotation axis A1 direction. Therefore, when the fastener 81 is arranged at the release position, the ring member 5 can be attached to and detached from the outer peripheral portion of the inner cylinder portion 41. On the other hand, at the fixed position, the fastener 81 is arranged so as to project radially outward from the outer diameter of the inner cylinder portion 41 when viewed from the rotation axis A1 direction.

As shown in FIG. 4, the fastener holding portion 83 includes a first holding portion 831 arranged on the upstream side in the clockwise direction D1 and a second holding portion 836 arranged on the downstream side. In the clockwise direction D1, the distance between the upstream end of the first holding portion 831 and the upstream end of the second holding portion 836 is the downstream end of the first locking portion 616 of the guide groove 61. Corresponds to the distance between and the downstream end of the second locking portion 617.

Both the first holding portion 831 and the second holding portion 836 are composed of a pair of locking pieces. The pair of locking pieces are integrally formed with the outer tubular portion 51, are separated from each other in the circumferential direction, and are provided so as to project forward from the front end of the outer tubular portion 51. The pair of locking pieces are flexible in the circumferential direction, and are provided with claws protruding from each other at the front end portion (tip portion) so as to be able to hold the fastener 81. Specifically, the pair of locking pieces can be inserted into the fastener 81 when they are bent by applying an external force in a direction close to each other in the circumferential direction. When the pair of locking pieces return to their initial positions, the claws at the tip hold the fastener 81 inseparably.

The blower device 1 having the above configuration is used by being attached to the outerwear 9 (see FIGS. 1 and 2) by the user. In addition to the outerwear 9, the blower 1 can be attached to and detached from clothes having a fan mounting portion 93 (see FIG. 2). The blower device 1 of the present embodiment can handle clothes of various thicknesses by the above-mentioned locking mechanism 6, rotation regulating mechanism 7, and additional locking mechanism 8.

Hereinafter, with reference to FIGS. 2, 4 and 10 to 14, the action of the blower 1 when attaching / detaching to / from clothing (for example, outerwear 9) (particularly, the locking mechanism 6, the rotation regulating mechanism 7, and the rotation regulating mechanism 7). The operation of the additional locking mechanism 8) will be described in detail.

When the blower 1 is attached to the outerwear 9, the user first inserts a part of the main body 3 in the state where the ring member 5 is removed as shown in FIG. 4 into the attachment opening 91 of the outerwear 9. (See Fig. 2). Specifically, the rear flange 43 is arranged on the outside of the rear body (fan mounting portion 93), and the inner cylinder portion 41 and the exhaust portion 46 are inserted from the mounting opening 91 into the inside of the outer garment 9. As a result, the fan mounting portion 93 (clothing) is arranged on the front surface of the rear flange 43.

The blower device 1 of the present embodiment is configured such that the ring member 5 is mounted on the housing 4 along a predetermined operation line. The "operation line" refers to a flow line or an operation line that is followed when the ring member 5 is mounted on the housing 4. Alternatively, it can be rephrased as the mounting direction when the ring member 5 is mounted on the housing 4. The motion line is typically represented as a linear or curved motion in a predetermined direction, or a combination of a plurality of such motions.

In the present embodiment, the ring member 5 is mounted on the housing 4 along an operation line combined in the order of the rotation axis A1 direction and the circumferential direction around the rotation axis A1. That is, the ring member 5 is mounted on the housing 4 by being relatively moved with respect to the housing 4 in the rotation axis A1 direction and then relatively moving in the circumferential direction. More specifically, the ring member 5 is moved relative to the housing 4 in the direction of the rotation axis A1 (in other words, the direction in which the front flange 52 approaches the rear flange 43), and then the clockwise direction D1. It is attached to the housing 4 by being relatively moved to.

The above-mentioned "in the order of the rotation axis A1 direction and the circumferential direction" means that the movement of the ring member 5 with respect to the housing 4 is generally seen while allowing some fluctuation in the rotation axis direction and the circumferential direction. , It means that the rotation is performed in the order of the rotation axis A1 direction and the circumferential direction. That is, the relative movement of the ring member 5 in the rotation axis A1 direction may be accompanied by a slight relative movement in the circumferential direction, and the relative movement of the ring member 5 in the circumferential direction is slightly in the rotation axis A1 direction. May be accompanied by relative movement of. Further, the transition from the rotation axis A1 direction to the circumferential direction may be performed as a transition accompanied by a sudden angle change, or may be performed as a gently continuous transition.

At the time of removal, the ring member 5 follows the operation line in the direction opposite to that at the time of mounting. That is, the ring member 5 is relatively moved in the circumferential direction with respect to the housing 4, and then is relatively moved in the rotation axis A1 direction. More specifically, the ring member 5 is relatively moved in the counterclockwise direction D2, and then relative to the direction away from the housing 4 in the direction of the rotation axis A1 (in other words, the direction in which the front flange 52 is separated from the rear flange 43). By being moved, it is removed from the housing 4.

As described above, since the inner diameter of the outer cylinder portion 51 is substantially the same as the outer diameter of the inner cylinder portion 41, the user aligns the locking projection 66 with any one of the three receiving ports 612. Unless, the ring member 5 cannot be fitted into the outer peripheral portion of the inner cylinder portion 41 of the housing 4. Therefore, the user first aligns the ring member 5 with respect to the housing 4 in the circumferential direction.

Specifically, the user grips the outer rear flange 43 of the outer garment 9 with one hand and the ring member 5 with the other hand to mark the reference protrusion mark 63 of the ring member 5. In the clockwise direction D1, the inner cylinder portion 41 is aligned with the reception port 612 closest to the upstream side of the first position mark 621. When the alignment is performed, the locking protrusion 66 corresponding to the reference protrusion mark 63 can enter the guide groove 61 in the rotation axis A1 direction from the receiving port 612 (see FIG. 5). The other two locking projections 66 can also enter the guide groove 61 via the other two receiving ports 612, respectively. Further, the claw 751 of the locking piece 75 can enter the guide recess 73. At this time, the fastener 81 of the additional locking mechanism 8 is in a state of being arranged at the release position.

The user moves the ring member 5 rearward with respect to the housing 4. By guiding the locking projection 66 along the first portion 611 of the guide groove 61, the ring member 5 is mounted and guided rearward with respect to the housing 4 in the direction of the rotation axis A1.

When the locking projection 66 is moved rearward to the position of the second portion 614, it is possible to move the ring member 5 in the clockwise direction D1 with respect to the housing 4 in addition to the rotation axis A1 direction. The user rotates the ring member 5 in the clockwise direction D1 with respect to the housing 4 and causes the locking projection 66 to enter the second portion 614. As the locking projection 66 enters the second portion 614 from the first portion 611, the claw 751 of the locking piece 75 separates from the guide recess 73 along the curved surface defining the guide recess 73. With the locking piece 75 bent outward in the radial direction, the claw 751 moves in the clockwise direction D1 along the outer peripheral surface of the inner tubular portion 41.

When the locking projection 66 is arranged in the second portion 614, the locking projection 66 is restricted from moving forward in the rotation axis A1 direction by the guide surface 615. On the other hand, since the width of the second portion 614 of the guide groove 61 is larger than the width of the locking projection 66 in the rotation axis A1 direction (in the front-rear direction (horizontal direction in FIG. 11)), the guide surface 615 and the rear flange 43 However, the allowable movement range varies depending on the thickness of the fan mounting portion 93 (clothing) arranged on the front side of the rear flange 43.

Depending on the thickness of the fan mounting portion 93 of the outerwear 9, the user can use the locking projection 66 until it is arranged at the first locking position shown in FIG. 11 or the second locking position shown in FIG. The ring member 5 can be rotated in the clockwise direction D1. The first locking position is a position where the front end (left end in FIG. 11) of the locking projection 66 abuts on the first locking portion 616. At the first locking position, the downstream end of the locking projection 66 in the clockwise direction D1 abuts on the step 618 formed on the downstream side of the first locking portion 616. The second locking position is a position where the front end (left end in FIG. 13) of the locking projection 66 abuts on the second locking portion 617. At the second locking position, the downstream end of the locking projection 66 in the clockwise direction D1 abuts on the downstream end of the second portion 614. Therefore, the user rotates the ring member 5 so that the front end surface of the locking projection 66 moves in the clockwise direction D1 along the guide surface 615 to move the locking projection 66 to the first locking position or. It can be easily and smoothly moved to the second locking position.

The distance W1 in the opposite direction (that is, the rotation axis A1 direction and the front-rear direction (left-right direction in FIG. 11)) between the front flange 53 and the rear flange 43 when the locking projection 66 is arranged at the first locking position. (See FIG. 11) is larger than the distance W2 (see FIG. 13) between the front flange 53 and the rear flange 43 when the locking projection 66 is arranged at the second locking position. The distance between the rear flange 43 corresponds to the thickness of the fan mounting portion 93 (clothing) that can be sandwiched between the front flange 53 and the rear flange 43. Therefore, the user uses a relatively thick coat 9. When the ring member 5 is rotated until the locking projection 66 is arranged at the first locking position, and the jacket 9 is made of a relatively thin material. The ring member 5 may be rotated until the locking projection 66 is arranged at the second locking position.

When the locking projection 66 is arranged at the first locking position, the reference projection mark 63 shown in FIG. 4 is arranged at a position facing the first position mark 621 of the inner cylinder portion 41. Thereby, the user can easily recognize that the locking projection 66 is arranged at the first locking position. As shown in FIG. 12, the locking projection 66 is arranged at the first locking position, and the claw 751 of the locking piece 75 enters the first recess 711 by the restoring force of the locking piece 75. , Engage with surface 712. As a result, the locking piece 75 is locked by the first recess 711. Further, the fastener 81 shown in FIG. 4 is arranged at a position facing the first holding portion 831.

When the thickness of the fan mounting portion 93 is relatively close to the distance W1, when the locking projection 66 is arranged at the first locking position, the fan mounting portion 93 is placed between the front flange 53 and the rear flange 43. It is held stably. When the locking projection 66 is locked to the first locking portion 616 in the front direction, the ring member 5 is separated from the housing 4 in the direction of the rotation axis A1 (in other words, the front flange 52 is separated from the rear flange 43). It is restricted to move in the direction). Further, by locking the locking piece 75 to the first recess 711 in the circumferential direction, the ring member 5 is restricted from rotating in the circumferential direction (particularly, the counterclockwise direction D2). Further, as shown in FIG. 10, when the user rotates the fastener 81 to a fixed position and engages with the first holding portion 831, the ring member 5 moves in the direction away from the housing 4, and the ring. The member 5 is restricted from rotating in the circumferential direction. As a result, the ring member 5 is stably fixed to the housing 4, and the blower 1 is securely attached to the jacket 9.

On the other hand, if the jacket 9 is made of a relatively thin material and the thickness of the fan mounting portion 93 is relatively small with respect to the distance W1, the locking projection 66 is allowed to move in the rotation axis A1 direction to some extent. Therefore, the attachment of the blower 1 to the outerwear 9 is not stable. Therefore, the user rotates the ring member 5 so that the locking projection 66 moves further downstream in the clockwise direction D1 from the first locking position. At this time, the claw 751 of the locking piece 75 once entered into the first recess 711 is separated from the first recess 711 along the surface 713 which is a gently inclined surface. With the locking piece 75 bent outward in the radial direction, the claw 751 moves in the clockwise direction D1 along the outer peripheral surface of the inner tubular portion 41.

When the locking projection 66 is arranged at the second locking position, the reference projection mark 63 shown in FIG. 4 is arranged at a position facing the second position mark 627 of the inner cylinder portion 41. Thereby, the user can easily recognize that the locking projection 66 is arranged at the second locking position. As shown in FIG. 14, the locking projection 66 is arranged at the second locking position, and the claw 751 of the locking piece 75 enters the second recess 716 by the restoring force of the locking piece 75. , Engage with surface 717. Further, the fastener 81 shown in FIG. 4 is arranged at a position facing the second holding portion 836.

When the thickness of the fan mounting portion 93 is relatively close to the distance W2 between the front flange 53 and the rear flange 43, the fan mounting portion 93 is stably sandwiched between the front flange 53 and the rear flange 43. Will be done. By locking the locking projection 66 forward to the second locking portion 617, the ring member 5 is restricted from moving in the direction away from the housing 4 (forward) in the direction of the rotation axis A1. Further, by locking the locking piece 75 to the second recess 716 in the circumferential direction, the ring member 5 is restricted from rotating in the circumferential direction. Further, when the user engages the fastener 81 with the second holding portion 836, it is restricted that the ring member 5 moves away from the housing 4 and that the ring member 5 rotates in the circumferential direction. As a result, the ring member 5 is stably fixed to the housing 4, and the blower 1 is securely attached to the jacket 9.

When removing the blower 1 from the jacket 9, the user first removes the ring member 5 from the housing 4. The user bends the pair of locking pieces of the first holding portion 831 or the second holding portion 836 in a direction close to each other, and moves the fastener 81 to the release position. The user further presses the tab 756 of the locking piece 75 locked in the first recess 711 or the second recess 716 in the counterclockwise direction D2 (or picks it with a finger and pulls it radially outward). The locking piece 75 is bent to release the locking. As a result, the ring member 5 is allowed to move in the circumferential direction with respect to the housing 4. The user rotates the ring member 5 in the counterclockwise direction D2 with respect to the housing 4 to move the locking projection 66 from the second portion 614 into the first portion 611. Then, the ring member 5 is relatively moved forward with respect to the housing 4, and the locking projection 66 is separated from the first portion 611. After removing the ring member 5 from the housing 4, the user removes the main body 3 from the outerwear 9.

When attaching / detaching the ring member 5 to / from the housing 4, the user puts his / her finger on the finger hook recess 432 formed on the rear flange 43 or the finger hook protrusion 55 provided on the ring member 5, and the housing 4 is attached / detached. And the ring member 5 can be gripped and both can be relatively rotated in the circumferential direction or relatively moved in the rotation axis A1 direction. As a result, the attachment / detachment operation can be easily performed.

As described above, in the present embodiment, as the locking mechanism 6, three locking projections 66 are provided for the three guide grooves 61, and when the ring member 5 is attached to and detached from the housing 4, each pair is provided. It is said to be in an engaging relationship. On the other hand, regarding the rotation regulating mechanism 7, only one locking piece 75 is provided for the three sets of rotation locking portions 71. Further, as for the additional locking mechanism 8, one fastener 81 is provided for one set of fastener holding portions 83.

Due to such a configuration, as in the above example, the alignment is performed using the reference protrusion mark 63, and the fastener 81 is engaged with the first holding portion 831 or the second holding portion 836. Of the three sets of rotary locking portions 71, only one specific set is used for locking the locking piece 75. However, when the additional locking mechanism 8 is not used, the user does not particularly perform the positioning by the reference protrusion mark 63, and the locking piece 75 is any one of the three sets of rotary locking portions 71. It may be locked to. From this point of view, three reference protrusion marks 63 are provided so as to correspond to all three locking protrusions 66, and three sets of first positions are provided so as to correspond to all three sets of rotational locking portions 71. The mark 621 and the second position mark 627 may be provided.

As described above, the user can attach / detach the blower 1 to / from the outerwear 9 or the clothes having the fan mounting portion 93. In the present embodiment, the blower 1 sandwiches the fan mounting portion 93 between the rear flange 43 and the front flange 53 arranged so as to face each other in the direction of the rotation shaft A1, and the ring member 5 is housed 4 by the locking mechanism 6. By locking the ring member 5 in the direction of the rotation axis A1, the ring member 5 is prevented from coming off the housing 4. In the present embodiment, as the locking position of the locking projection 66 in the rotation axis A1 direction, a first locking portion 616 and a second locking portion 617 having different positions in the rotation axis A1 direction are provided. The blower 1 can handle a plurality of types of clothes having different thicknesses.

In particular, the first locking portion 616 and the second locking portion 617 are on a path through which the locking projection 66 can pass in the process of mounting the ring member 5 on the housing 4 along a predetermined operation line by the user. Specifically, it is formed in the guide groove 61 (guide surface 615)). Therefore, the user may lock the locking projection 66 at any of the appropriate locking positions in the series of mounting operations. That is, the user does not need to temporarily remove the ring member 5 from the housing 4 and reattach it in order to change the locking position. As described above, the blower 1 of the present embodiment can easily handle a plurality of types of clothes having different thicknesses.

Further, the ring member 5 is mounted on the housing 4 by being relatively moved with respect to the housing 4 in the order of the rotation axis A1 direction (rearward) and the circumferential direction (clockwise direction D1) along the operation line. The first locking portion 616 and the second locking portion 617 are provided in the second portion 614 of the guide groove 61 extending in the circumferential direction. Therefore, unless the locking projection 66 is once moved in the circumferential direction (counterclockwise direction D2), the locking of the first locking portion 616 or the second locking portion 617 in the rotation axis A1 direction may be released. Absent.

Further, the rotation regulating mechanism 7 restricts the ring member 5 from moving in the circumferential direction (counterclockwise direction D2) with respect to the housing 4. With such a configuration, the possibility that the ring member 5 comes off from the housing 4 can be further reliably suppressed. The locking piece 75 is configured to be locked in the first recess 711 or the second recess 716 according to the rotational operation of the ring member 5 with respect to the housing 4 in the circumferential direction (clockwise direction D1). Therefore, the user can operate both the locking mechanism 6 and the rotation regulating mechanism 7 only by mounting the ring member 5 on the housing 4 along a predetermined operation line.

In the present embodiment, in addition to the locking mechanism 6 and the rotation restricting mechanism 7, an additional locking mechanism 8 for restricting the movement of the ring member 5 with respect to the housing 4 in the rotation axis A1 direction and the rotation in the circumferential direction is provided. There is. Therefore, even if the locking mechanism 6 or the rotation regulating mechanism 7 does not function, the additional locking mechanism 8 can fulfill the function, so that the possibility that the ring member 5 will come off from the housing 4 is further ensured. It can be suppressed.

Furthermore, since the color of the ring member 5 is different from that of the housing 4, the user can clearly distinguish the ring member 5 from the housing 4. As a result, it is possible to immediately understand which member should be relatively moved with respect to which member, so that the attachment / detachment operation (particularly, the operation of removing the ring member 5 from the housing 4) becomes easy.

The above-described embodiment is merely an example, and the blower and clothing according to the present invention are not limited to the configurations of the blower 1 and the jacket 9 illustrated. For example, the configurations of the blower 1 and the jacket 9 can be appropriately changed according to the desired additional functions. The blower 10 and the outerwear 9 according to the modified example will be described with reference to FIGS. 15 to 19. In the following, for convenience, the same configurations as those of the blower 1 (see FIGS. 3 to 14) of the above embodiment (including substantially the same configurations with slight differences) are designated by the same reference numerals. However, the description and illustration will be omitted or simplified as appropriate.

First, the blower 10 will be described. As shown in FIGS. 15 to 17, the blower device 10 includes a main body portion 30 and a ring member 50. The main body 30 includes a motor 33 and a fan 36 having the same configuration as the main body 3 of the above embodiment. The housing 40 and the ring member 50 of the main body 3 include a locking mechanism 6 (see FIG. 4) having the same configuration as that of the above embodiment, while having a rotation regulating mechanism 7 (see FIG. 4) having a slightly different configuration. ..

In the rotation regulation mechanism 7 of this modification, only the tab 757 of the locking piece 75 is slightly different from the tab 756 (see FIG. 12) of the above embodiment. Specifically, as shown in FIG. 12, the tab 756 of the above embodiment protrudes to substantially the same position as the edge of the front flange 53, whereas as shown in FIGS. 15 and 16, the present modification Then, the tab 757 protrudes radially outward from the edge of the front flange 53. With this configuration, the user can easily grasp the position of the tab 757 to be operated when the ring member 50 is removed from the housing 40. Further, the tip portion of the tab 757 (specifically, a portion protruding radially outward from the edge of the front flange 53) has a color different from that of the other portion of the ring member 50. Thereby, the visibility of the tab 757 can be further improved.

Further, in this modification, the additional locking mechanism 8 (see FIG. 4) is not provided. In such a case, as described in the above embodiment, the user may make the three locking projections 66 correspond to the three guide grooves 61 in any way. Therefore, as shown in FIGS. 15 and 16, the housing 40 and the ring member 50 are provided with three reference protrusion marks 63, and three sets of the first position mark 621 and the second position mark 627.

Further, as described in the above embodiment, in the process of attaching or detaching the ring member 50 to the housing 40, the user needs to rotate the ring member 50 in the circumferential direction with respect to the housing 40. Therefore, in the present embodiment, the rotation direction display portion 57 is provided on the flange-shaped front end surface of the outer cylinder portion 51 of the ring member 50. The rotation direction display unit 57 has a first mark 571 (a symbol of an arrow and a locked key) indicating the rotation direction of the ring member 50 at the time of attachment and a second mark 572 (the design of the key locked with an arrow) indicating the rotation direction of the ring member 50 at the time of removal. Includes arrows and unlocked key symbols).

Further, as shown in FIGS. 15 to 17, the housing 40 is provided with an engaging arm 481. The engaging arm 481 is configured to be engageable with a fan holding belt 98 (see FIGS. 19 and 20) provided on the jacket 90 described later. Specifically, a region in which the first rib 463 is not provided is provided in a part of the exhaust portion 46 in the circumferential direction. This region constitutes a belt passing region 48 when the fan holding belt 98 is mounted on the engaging arm 481. The engaging arm 481 is a substantially U-shaped portion that is supported on both sides of the belt passing region 48 in the circumferential direction and projects forward. The mounting of the fan holding belt 98 will be described later.

Also in this modification, the housing 40 is provided with the same connector arrangement area 38 as the housing 4 of the above embodiment. As shown in FIGS. 16 and 17, when the connector 973 of the cable 97 is connected to the connector 37 of the main body 3 and arranged in the connector arrangement area 38, the regulation rib 381 abuts on the connector 973 from the radial outside. Prevents the connector 973 from coming off.

Next, the outerwear 90 configured so that the blower 10 can be attached and detached will be described. As shown in FIG. 18, the outerwear 90 includes a hood 900 integrally sewn to the body portion. Therefore, when the blower device 10 is attached to the outerwear 90, the air sent out into the outerwear 90 can flow to the hood 900 to cool the user's head. The hood 900 may be attached to and detached from the body with a fastener or a button.

Most of the outerwear 90, including the hood 900, is made of natural fibers, synthetic fibers, or a blend of these fabrics, including fabrics that have been surfaced to prevent air from leaking out. On the other hand, in the hood 900, a mesh portion 903 using a mesh fabric is provided in a predetermined area corresponding to a position facing both ears when the user wears the hood 900. As a result, the user can easily hear the surrounding sounds even when wearing the hood 900. The mesh portion 903 may be shielded by a flap (not shown).

As shown in FIG. 19, the outerwear 90 has mounting openings 91 (fan mounting portions 93) formed at two locations on the back surface portion, similarly to the outerwear 9 (see FIG. 8) of the above embodiment. Further, in this modification, a fan holding belt 98 is attached to the back surface of the outerwear 90. The fan holding belt 98 is configured to prevent the blower device 10 from falling off from the jacket 90 by engaging with the engagement arm 481 of the blower device 1 described above. More specifically, the fan holding belt 98 is made of a flexible material (eg, fabric) in a strip shape, one end of which is sewn onto the jacket 90 above the fan mounting portion 93. A pair of hook buttons (snap buttons) 981 are attached to both ends of the fan holding belt 98. Therefore, as shown on the right side of FIG. 19, when the hook button 981 is removed, the fan holding belt 98 extends in a band shape with one end as a free end. On the other hand, as shown on the left side of FIG. 19, when the hook button 981 is fastened, the fan holding belt 98 is looped and both ends are fixed to the jacket 90.

The usage mode of the fan holding belt 98 will be described with reference to FIGS. 19 and 20. As shown on the right side of FIG. 19, the user attaches the blower 10 to the fan mounting portion 93 of the jacket 90 as described in the above embodiment with the hook button 981 of the fan holding belt 98 removed. Install. Then, as shown in FIG. 20, the fan holding belt 98 is passed through the belt passing region 48, the fan holding belt 98 is looped in a state surrounding the engaging arm 481, and the hook button 981 is fastened to fasten the outerwear 9. Attach to. Thereby, even if the locking mechanism 6 is released from the lock for some reason, the fan holding belt 98 can prevent the main body portion 30 from coming off from the fan mounting portion 93 and falling off. Therefore, the possibility of damage to the motor 33 and the fan 36 housed in the housing 40 can be reduced.

When the main body portion 30 is detached from the fan mounting portion 93, the main body portion 30 falls off to the outside of the outer garment 90 on which the rear flange 43 is arranged. In this modification, the fan attached to the inside of the outer garment 90 with respect to the engaging arm 481 provided in the portion of the housing 40 arranged inside the outer garment 9 (specifically, the exhaust portion 46). The holding belt 98 is engaged. Therefore, the fan holding belt 98 can hold the main body portion 30 more reliably than the case where the fall prevention mechanism is provided on the outside of the jacket 90. Further, since the fan holding belt 98 is arranged on the side of the ring member 50 in the direction away from the housing 40, it is possible to prevent not only the main body 30 but also the ring member 50 from falling off. ..

Further, if the blower device 10 rotates with respect to the jacket 90 as the motor 33 is driven and the fan 36 rotates, an extra load may be applied to the cable 97 and the blower device 10. In addition, the orientation of the closed portion 451 (see FIG. 6) configured as a design surface may change in a direction different from the original orientation. On the other hand, the fan holding belt 98 can function not only as a fall-out prevention mechanism but also as a rotation regulation mechanism that regulates the rotation of the blower 10 with respect to the jacket 90.

In this modification, the engagement arm 481 is a configuration example corresponding to the "engagement portion" of the present invention. The fan holding belt 98 having the hook button 981 is a configuration example corresponding to the "fall-off prevention mechanism" of the present invention. The engagement mode of the engaging portion and the dropout prevention mechanism and the arrangement position thereof are not limited to those illustrated in this modification, and may be changed as appropriate. For example, as another configuration example of the fall-out prevention mechanism, one end is attached to the outerwear 90, the other end is a band-shaped member having a hook that can be engaged with the engaging arm 481, and one end is attached to the outerwear 90. And examples thereof include a string-shaped member capable of connecting the other end to the engaging arm 481. Further, for example, a hook is adopted instead of the engaging arm 481, one end is attached to the jacket 90 instead of the fan holding belt 98, and the other end is a band-shaped member having an annular member that can engage with the hook. Alternatively, a string-shaped member may be adopted.

In addition to the above modifications, the changes illustrated below can be made. It should be noted that these modifications are such that only one or a plurality of these are the inventions described in the blower devices 1, 10 and outerwear 9, 90 shown in the above-described embodiments and modifications, or each claim. Can be adopted in combination.

As long as the ring member 5 is detachably configured with respect to the housing 4, the configurations of the housing 4 and the ring member 5 may be changed as appropriate. For example, the configuration of the intake portion 45 and the exhaust portion 46 of the housing 4 (arrangement of the intake port 457 and the exhaust port 467, etc.) may be changed. From the viewpoint of ease of attachment / detachment operation, it is preferable that the housing 4 has a cylindrical portion at least in part, and the ring member 5 has a cylindrical portion that can be fitted externally to the cylindrical portion of the housing 4.

The configuration in which the fan mounting portion 93 (clothing material) can be sandwiched is not limited to the rear flange 43 and the front flange 53. For example, the rear flange 43 and the front flange 53 do not necessarily have to surround the entire circumference of the inner cylinder portion 41 and the outer cylinder portion 51, and for example, a part in the circumferential direction may be cut out or a part thereof. May be provided with an opening. From the viewpoint of more reliably sandwiching the clothing material, it is preferable that the rear flange 43 and the front flange 53 have substantially the same outer diameter, but the outer diameters may be different.

The locking mechanism 6 may be configured to restrict the movement of the ring member 5 with respect to the housing 4 in the rotation axis A1 direction by locking the ring member 5 with respect to the housing 4 in the rotation axis A1 direction. The configurations provided in the housing 4 and the ring member 5 are not limited to the guide groove 61 and the locking projection 66, respectively. For example, the arrangement relationship may be reversed and the locking projection 66 may be provided on the outer peripheral surface of the housing 4, while the guide groove 61 may be provided on the inner peripheral surface of the ring member 5. The number of guide grooves 61 and locking projections 66 is not limited to three, but from the viewpoint of more reliable locking, it is preferable to provide a plurality of sets.

Further, the shapes of the guide groove 61 and the locking projection 66, the locking position of the locking projection 66, and the like may be appropriately changed. For example, the guide groove 61 may be formed as a through hole instead of a recess. Further, in order to be able to respond more finely to the difference in the thickness of the clothing material, three or more locking positions may be provided in which the locking projection 66 is locked in the direction of the rotation axis A1.

Further, the operation line (mounting direction) when the ring member 5 is mounted on the housing 4 can be appropriately changed. In the above-described embodiment, the guide surface 615 of the guide groove 61 is formed so as to be gently inclined rearward in the clockwise direction D1, so that the ring member 5 is rotated and the first locking is performed. It is possible to smoothly perform the operation of moving the locking projection 66 to the portion 616 or the second locking portion 617 without distinction. However, the guide surface 615 may be formed in a stepped shape including a surface corresponding to the first locking portion 616 and the second locking portion 617. Further, for example, a second portion extending in the clockwise direction D1 and a third portion extending in the counterclockwise direction D2 may be provided on both sides of the first portion 611, respectively. The wall surface defining the front end of the second portion and the wall surface defining the front end of the third portion may be different in position in the direction of the rotation axis A1. In this case, the ring member 5 is relatively moved in the rotation axis A1 direction (rearward) with respect to the housing 4, and then is relatively moved in the clockwise direction D1 or the counterclockwise direction D2 according to the thickness of the clothing material. become.

Further, for example, as in the modified example shown in FIG. 21, a locking mechanism 600 including a locking portion 64 and a locking piece 67 may be adopted instead of the locking mechanism 6. In FIG. 21, for simplification, only a partial cross section of the inner tubular portion 410 of the housing 4 and the outer tubular portion 510 of the ring member 5 is schematically shown.

The locking portion 64 is formed by a plurality of locking grooves 640 having a V-shaped cross section formed on the outer peripheral surface of the inner tubular portion 410 along the rotation axis A1 direction (front-rear direction). Of the two surfaces defining each locking groove 640, the front surface 641 (the surface on the left side in FIG. 21) is arranged so as to be substantially orthogonal to the rotation axis A1 and the rear surface 642 (the surface on the right side in FIG. 21). The surface) is arranged so as to incline in the radial direction toward the rear. Each locking groove 640 defines a locking position of the locking piece 75. On the other hand, the locking piece 67 is integrally formed with the outer tubular portion 510 as a flexible strip-shaped member so as to extend in the central axis A2 direction (front-rear direction) of the outer tubular portion 510. The locking piece 67 has the same configuration as the locking piece 75 (see FIG. 12) of the above-described embodiment, and has a claw 671 that can be locked in the locking groove 640 inside the rear end portion which is the tip portion. And has a tab 672 on the outside. It is preferable that a plurality of locking portions 64 and locking pieces 67 are provided in the circumferential direction of the inner cylinder portion 410 and the outer cylinder portion 510, respectively.

In the blower device provided with the locking mechanism 600, the ring member 5 is attached / detached by being relatively moved in the direction of the rotation axis A1 with respect to the housing 4. That is, unlike the above-described embodiment in which the rotation axis A1 direction and the circumferential direction are relatively moved, the ring member 5 does not need to be relatively moved in the circumferential direction with respect to the housing 4. Therefore, in this modification, the rotation regulation mechanism 7 does not have to be provided. However, from the viewpoint of more reliably preventing the locking piece 67 from coming off from the locking portion 64 in the circumferential direction, for example, both sides of the locking portion 64 in the circumferential direction are in contact with the locking piece 67 to rotate. It is preferable that a wall portion for restricting movement in a direction is provided.

When the ring member 5 is mounted on the housing 4, the user aligns the locking portion 64 and the locking piece 67 so as to face each other in the radial direction. Then, the outer tubular portion 510 is moved rearward with respect to the inner tubular portion 410, and the locking piece 67 is locked in an appropriate locking groove 640 according to the thickness of the fan mounting portion 93 (clothing). In this way, the user can push the ring member 5 into the housing 4 by simply pushing the ring member 5 into the rotation axis A1 direction (specifically, rearward) to an appropriate locking position according to the clothing material. Can be installed.

Regarding the configurations of the rotation regulating mechanism 7 and the additional locking mechanism 8, similarly to the locking mechanism 6, the arrangement relationship between the rotation locking portion 71 and the locking piece 75 and the arrangement relationship between the fastener 81 and the fastener holding portion 83 are as follows. It can be changed as appropriate, such as reversing. Further, the rotation regulating mechanism 7 and the additional locking mechanism 8 do not necessarily have to be provided. When the additional locking mechanism 8 is used in combination with the locking mechanism 6, it is preferable to regulate at least the rotation of the ring member 5 with respect to the housing 4 in the circumferential direction.

The finger hook recess 432 and the finger hook protrusion 55 are preferably provided from the viewpoint of improving operability, but either one or both may be omitted.

The garment to which the blower 1 can be attached and detached does not have to be an upper garment such as a jacket 9, and may be a lower garment such as pants. Further, when the garment has a two-layer structure of the outer material and the lining, the fan mounting portion 93 is provided on the outer material, and when the blower 1 is attached, the exhaust portion 46 is arranged in the internal space between the outer material and the lining. May be good. In this case, the air sent to the internal space can be discharged to the outside by appropriately providing a portion (opening) in which the outer material and the lining are not sewn on the collar or the side. Further, the position and number of the fan mounting portions 93 on the clothes can be changed as appropriate.
