  However, in the above-described conventional proposal, the hair bundle is bare except for the portion for holding the proximal end side of the hair bundle and maintaining the shape of the brush body. For example, in Patent Document 1, the hair bundle is exposed at portions other than the holding rod body that holds the proximal end side of the hair bundle and the attachment portion that holds the brush. However, the gap between the hair bundles remains open, and the foreign matter may enter from the gap between the hair bundles. For this reason, the gap between the opening / closing member and the building is completely blocked. I couldn't do it. In particular, at the proximal end of the hair bundle, the hair bundle is a collection of many brush hairs, so the spacing between the hair bundles is wider than the other parts, and the problem of foreign matter intrusion is significant. is there.

  In addition, depending on the situation of the attachment location of the gap brush, in order to close the gap between the opening / closing member and the building, the attachment member itself has an angled shape, and the tip of each hair bundle is oblique to the opening / closing member.

It should be noted that the expressions of the top, bottom, front, back, left and right in the claims and the description of the present application only indicate a relative positional relationship, and do not specify an absolute position.

  The gap brush according to the present invention comprises a brush body 1 and an attachment member 2 as shown in FIG. That is, the basic configuration is the same as that shown in Patent Document 1 and Patent Document 2.

  As shown in FIG. 2, the brush body 1 is flat in the front-rear direction, and includes a plurality of hair bundles 11 and a brush base portion 12. A plurality of the brush bodies 1 are arranged in tandem in the left-right direction to constitute a gap brush.

  The hair bundle 11 is a collection of a large number of brush hairs 111 formed of a soft plastic wire. The material of the brush hair 111 can be formed using other materials such as animal hair as long as it has flexibility, durability, and weather resistance.

  The brush base portion 12 is a member made of hard plastic and extends continuously in the left-right direction, and its cross-sectional shape is a trapezoidal shape that is tapered from the base end side toward the tip end side. However, the cross-sectional shape of the brush base 12 is not limited to this, and may be a rectangular shape or a shape having a curved surface.

  The base ends of the bristles 11 penetrate the brush base 12 in the vertical direction and protrude from the upper end of the brush base 12. Thereby, the hair | bristle bundle 11 is arranged on the brush base 12 in the left-right direction. Further, two rows of hair bundles 11 are arranged on the brush base 12 in the front-rear direction, and one row and the other row of the hair bundle 11 are staggered. Thereby, the space | gap between the hair | bristle bundles 11 can be made small compared with arranging the hair | bristle bundle 11 in two rows and the same position in the front-back direction. The length of the hair bundle 11 is set so that it can contact the shutter plate 51 or the floor surface 57 when the gap brush is attached, as shown in FIGS. The surface of the shutter plate 51 has uneven undulations, but a length that can contact the undulations is also required.

  The attachment member 2 includes a movable member 21, a rail 22, and a holder 23.

  As shown in FIG. 3, the rail 22 has a U-shaped cross section, and includes a holder attaching / detaching portion 22a and a brush supporting portion 22b. In this example, the rail 22 is formed of an aluminum alloy, but it can also be formed using a material other than metal such as iron, other metals, or plastic.

  As shown in FIG. 4, the holder detachable portion 22a includes a building-side fixing portion 22ai, a front holder detachable portion 22aj located in front of the center of the cross section of the rail 22, and a rear holder detachable portion 22ak located in the rear. .

  Building side fixing | fixed part 22ai is a rectangular plate-shaped body, and touches attachment locations, such as a wall surface of a building. In the building-side fixing portion 22ai in this example, a fixing hole 22ai1 for fixing the screw S through is prepared. However, as shown in FIG. 6B and FIG. 7, the rail 22 may have a shape other than the “U” shape, and a fixing hole 22 a i 1 may be provided in any part of the rail 22.

  The front holder attaching / detaching portion 22aj is a rectangular plate-like body provided so as to protrude in the vertical direction (upward in FIG. 4) with respect to the building side fixing portion 22ai along the long side of the building side fixing portion 22ai. Is provided so as to protrude from the front holder attaching / detaching portion 22aj so that the holding portion 22aj1 for engaging with the holder 23 faces the inside of the "U" shape so that the holder 23 does not come out upward. At the time of the engagement, the front rail attaching / detaching portion 23bi of the holder 23 contacts the lower surface in FIG. 4 of the pressing portion 22aj1.

  The rear holder attaching / detaching portion 22ak is provided so as to protrude upward in FIG. 4 with respect to the building side fixing portion 22ai along the long side of the building side fixing portion 22ai. This protrusion is a rectangular plate-like body that is slightly inclined toward the inside of the “U” shape as it goes from the base end side to the tip end side with respect to the vertical direction with respect to the building-side fixing portion 22ai. Thereafter, the tip of the holder attaching / detaching portion 22ak is located above the tip of the front holder attaching / detaching portion 22aj in FIG.

  A brush support portion 22b having an arcuate cross section is provided at the tip of the rear holder attaching / detaching portion 22ak, which serves as a fulcrum when the movable member 21 moves in contact with a fulcrum portion 213b1 of the movable member 21 described later. In addition, a pressing portion 22ak1 for engaging with the holder 23 is provided on the inner side of the “U” shape so that the holder 23 does not come out upward under the brush support portion 22b. At the time of the engagement, the rear rail attaching / detaching portion 23bj of the holder 23 is in contact with the lower surface of the pressing portion 22ak1 in FIG.

  The holder 23 has a Greek letter “λ” in cross-sectional shape and fits into the rail 22. The holder 23 is made of plastic. More specifically, the holder 23 is formed of AS resin (acrylonitrile-styrene copolymer) together with the movable member 21, and has impact resistance, durability, weather resistance, and slidability. As long as it is a material, it can be formed using various materials such as other types of plastics, aluminum alloys, and other metals. However, it is not preferable to use metal (aluminum alloy or the like) for both the rail 22 and the holder 23 from the viewpoint of easy attachment / detachment of the holder 23 from the rail 22 described later (however, as shown in FIGS. 5 to 7). Except when the rail 22 and the holder 23 are integrated).

  As shown in FIG. 4, a movable member corresponding portion 23 a having a semicircular cross section that is located rearward with respect to the center of the cross section of the rail 22, and a front rail that is branched from the middle of the movable member corresponding portion 23 a and extends forward. The part 23bi and the rear rail attaching / detaching part 23bj protruding from the lower end part 23a2 in FIG. 4 of the movable member corresponding part 23a are provided. The movable member corresponding portion 23a is provided at a position where the center of the semicircular arc substantially coincides with the brush support portion 22b when the holder 23 is engaged with the rail 22. Also, the movable member corresponding portion 23a and the rear rail attaching / detaching portion 23bj are formed with a small plate thickness (in a groove shape), and an external force for deforming the positional relationship between the two compared to the case where the plate thickness is equal. Can be reduced. Therefore, the engaging portion 23bj1 of the rear rail attaching / detaching portion 23bj can be engaged with or released from the pressing portion 22ak1 of the rail 22 relatively easily.

  In the movable member corresponding portion 23a, concave grooves 23a1 for engaging with a holder corresponding portion 213a of the movable member 21, which will be described later, are provided inside the semicircular arc shape at equal intervals along the arc. The concave groove 23a1 has a semicircular cross section. The shape and interval of the groove 23a1 are formed in correspondence with a ridge 213a3 provided on the movable member 21, which will be described later, and fit while allowing the movable member 21 to rotate. The interval in the circumferential direction of each concave groove 23a1 to 23a1 is between adjacent virtual lines connecting the center in the semicircular cross section of each concave groove 23a1 to 23a1 from the center in the arc-shaped cross section of the brush support portion 22b. The angle α between them is set to 15 degrees. The angle α can be appropriately changed in design.

  Further, when the holder 23 is engaged with the rail 22, the lower end portion 23 a 2 in FIG. 4 of the movable member corresponding portion 23 a is in contact with the building-side fixing portion 22 ai of the rail 22. And the engaging part 23bj1 which is an upper end part in FIG. 4 of the rear rail attaching / detaching part 23bj contacts the pressing part 22ak1 of the rail 22. Thereby, the rear rail attaching / detaching portion 23bj of the holder 23 is engaged with the rear holder attaching / detaching portion 22ak of the rail 22.

  At the time of the engagement, the lower end portion 23bi1 in FIG. 4 of the front rail attaching / detaching portion 23bi comes into contact with the building-side fixing portion 22ai of the rail 22. And the side part 23bi2 which protruded ahead in FIG. 4 of the front rail attaching / detaching part 23bi contacts the pressing part 22aj1 of the front holder attaching / detaching part 22aj. Thereby, the front rail attaching / detaching portion 23bi of the holder 23 is engaged with the front holder attaching / detaching portion 22aj of the rail 22.

  Further, the front rail attaching / detaching portion 23bi is provided with a corner cutout portion 23bi3 so that a gap is formed between the front rail attaching / detaching portion 22aj of the rail 22 during the engagement. As shown in FIG. 4, in addition to a wedge-shaped tool such as a flat-blade screwdriver, a tip of a coin or the like is inserted in a gap formed between the front rail attaching / detaching portion 23bi and the holding portion 22aj1 of the front holder attaching / detaching portion 22aj of the rail 22. When a flat shape is inserted, the engagement can be easily removed. As a result, the holder 23 can be removed while the rail 22 is fixed to an attachment location such as a wall surface of the building, and the components can be easily replaced. For example, a tool such as a flathead screwdriver or a tool for releasing the engagement such as a coin can be brought into contact with each of the holding portion 22aj1 serving as a fulcrum and the corner cutout portion 23bi3 serving as an action point. Any device may be used as long as the tool can be sandwiched in the gap and the engagement can be separated. However, the present invention is not limited to the structure in which the rail 22 and the holder 23 described above are formed separately. For example, the rail 22 and the holder 23 are integrated as shown in FIGS. It may be formed.

  The movable member 21 is made of plastic, and as shown in FIG. 3, a holding portion 211 that holds the brush base portion 12, a concealing portion 212 that extends from the holding portion 211 to the tip, and a base end side of the holding portion 211. The fixed portion 213 is provided.

  The holding unit 211 includes a front holding unit 211 a that holds the front side of the brush base 12 and a rear holding unit 211 b that holds the rear side of the brush base 12. In this example, the front holding part 211a and the rear holding part 211b are provided facing each other in the front-rear direction. Protrusions extending in the left-right direction are provided to support the brushes on the inside of the base end side and the front end side of the front holding portion 211a and the inside of the base end side and the front end side of the rear holding portion 211b, respectively. The proximal end projection of the front holding portion 211a is the front proximal end projection 211at1, the front end projection of the front holding portion 211a is the front distal end projection 211at2, and the proximal projection of the rear holding portion 211b is the rear proximal projection. 211 bt 1, the front end side protrusion of the rear holding portion 211 b is the rear front end side protrusion 211 bt 2. The front proximal end projection 211at1 and the rear proximal end projection 211bt1, and the front distal end projection 211at2 and the rear distal projection 211bt2 are paired in the front-rear direction. The front proximal end projection 211at1 and the rear proximal projection 211bt1 support the proximal end of the brush base 12, and the front distal projection 211at2 and the rear distal projection 211bt2 support the distal end of the brush base 12. As a result, the brush body 1 is held by the movable member 21.

  The concealing part 212 includes a front concealing part 212a extending from the front holding part 211a to the front end and a rear concealing part 212b extending from the rear holding part 211b to the front end. The concealing unit 212 conceals the gap between the hair bundles 11 by covering the front and rear surfaces of the hair bundle 11 in the brush body 1 with the brush body 1 held by the movable member 21. By providing the concealing part 212 in this way, foreign matter can be prevented from entering through the gaps between the hair bundles 11, and the gap between the opening / closing member and the building can be effectively blocked to increase the sealing degree. .

  The fixed portion 213 includes a holder corresponding portion 213a formed on the front surface side and a rail corresponding portion 213b formed on the rear surface side. The holder corresponding part 213a and the rail corresponding part 213b are integrated at the base end. The boundary portion between the two is formed thin (in a groove shape) and can exhibit elasticity, so that the movable member 21 can be easily rotated during angle adjustment as will be described later.

  The holder-corresponding portion 213a has an angle adjusting portion 213a1 having a semicircular cross-sectional shape on the proximal end side, and a rectangular shape extending from the angle adjusting portion 213a1 to the distal end and connected to the proximal end of the front holding portion 211a. The stopper part 213a2 which is a plate-shaped body is provided.

  On the outer side of the semicircular arc shape in the angle adjusting part 213a1, a protruding line 213a3 for engaging with the movable member corresponding part 23a of the holder 23 is provided. The ridges 213a3 are provided at equal intervals in the direction along the arc. The protrusion 213a3 has a semicircular cross-sectional shape. The shape and interval of the ridges 213a3 are formed so as to correspond to the concave grooves 23a1 provided in the movable member corresponding portion 23a of the holder 23 so that the movable member 21 is allowed to rotate.

  The rail-corresponding portion 213b has a “<” shape in cross-section, and the arc of the holder-corresponding portion 213 a and the bending direction of the “<” shape of the rail-corresponding portion 213 b are the same. Since the fixed portion 213 is positioned in the space between the rear holder attaching / detaching portion 22ak of the rail 22 and the movable member corresponding portion 23a of the holder 23, as described above, the direction in which the bending direction is the same is as follows. There exists an advantage that it can be made compact in the state which combined each member.

  A bent portion in the “<” shape of the rail corresponding portion 213b is a fulcrum portion 213b1. The fulcrum part 213b1 has a circular cross section. When the rail corresponding part 213b and the brush support part 22b of the rail 22 are in contact with each other, the movable member 21 can be rotated with respect to the holder 23 with the brush support part 22b as a fulcrum. The fulcrum part 213b1 and the brush support part 22b of the rail 22 are formed with the same curvature. Therefore, both can touch and can be rotated smoothly.

  The rotation region of the movable member 21 in this example has an upper limit at a position where the tip end portion 23a3 of the movable member corresponding portion 23a of the holder 23 abuts on the stopper portion 213a2 of the movable member 21, and the rear holder attaching / detaching portion of the rail 22 This is a region whose lower limit is a position where the rear end surface of 22ak and the portion corresponding to the tip side of the fulcrum part 213b1 in the rail corresponding part 213b of the movable member 21 abut. The movable member 21 rotates within the region.

  The holder corresponding portion 213a of the movable member 21 is pressed and compressed by the rail 22 and the holder 23 by engaging with the movable member corresponding portion 23a of the holder 23 fitted in the rail 22. Thereby, the front and rear opening of the holding part 211 and the concealing part 212 of the movable member 21 is suppressed.

  The brush base 12 is held by the front holding portion 211a and the rear holding portion 211b of the movable member 21. At this time, the front concealing part 212 a is arranged on the front surface on the proximal end side of the hair bundle 11 fixed to the brush base part 12, and the rear concealing part 212 b is arranged on the rear surface on the proximal end side of the hair bundle 11. Thus, by covering the proximal end side of the hair bundle 11 with the concealing portion 212, the gap between the hair bundles 11 can be concealed.

  As described above, when the mounting is completed (when the front and rear opening of the concealing part 212 is suppressed), the distance between the front concealing part 212a and the rear concealing part 212b is the front and rear width of the bristle bundle 11 of the brush (front and front rows and front rows). The length of the masking portion 212 can be set to be substantially equal to or larger than the length of the rear surface so that the tip of the concealing portion 212 is in contact with the hair bundle 11 or the interval is increased. Furthermore, it is also desirable to set this interval smaller than the front-rear width of the bristle bundle 11 of the brush (the length between the front face of the front row and the rear face of the rear row). Thereby, the concealment part 212 presses the hair bundle 11 in the front-rear direction, and the hair bundle 11 spreads in the left-right direction, so that the interval can be narrowed so that the eyes between the hair bundle 11 and the hair bundle 11 are clogged. . Further, as described above, the concealing portion 212 is coordinated on both the front and rear surfaces of the proximal end side of the hair bundle 11, but in order to exert the effect of closing the gap between the hair bundles 11, It may be coordinated to at least one of the front surface and the rear surface on the base end side, and may have different shapes on the front and rear surfaces. Further, the concealing portion 212 of this example is curved inward as it goes from the proximal end side to the distal end side, but by doing so, the gap between the concealing portion 212 and the hair bundle 11 can be reduced as much as possible, In addition, it can be designed to look good.

  As described above, the plurality of brush bodies 1 are arranged in tandem in the left-right direction in a state where the ends of the brush base 12 are abutted with each other. As shown in FIG. 2, the abutting end portions 12 a and 12 b of the brush base portion 12 are flat surfaces inclined rightward or leftward from the front to the rear. Thereby, the hair | bristle bundle 11 can be wrapped in the front-back direction in the said butt | matching edge parts 12a and 12b. If the butted ends 12a and 12b are perpendicular to the direction in which the brush base 12 extends, there is a problem that if there is a gap between the brush bases 12, a gap also occurs between the hair bundles 11 as they are. is there. On the other hand, in this example, since the hair bundle 11 can be wrapped in the front-rear direction as described above, even if a gap is formed between the brush base portions 12, it is assumed that the hair bundle 11 occurs between the hair bundles 11. The gap can be eliminated as much as possible.

  In addition, the positional relationship between the butted end portions 12a and 12b and the hair bundle 11 in this example is determined by separating the butted end portions 12a and 12b with respect to the distance between the hair bundles 11 arranged in the left-right direction in each front and rear row of the hair bundle 11. The distance between the hair bundles 11 and the distance between the hair bundles 11 other than the butted ends 12a and 12b are set to be equal. In addition, although it may be set to other than that, from the viewpoint of eliminating the gap between the hair bundles 11, the distance between the hair bundles 11 separating the butted end portions 12a and 12b is referred to as the butted end portion 12a, It is desirable to make it smaller than the distance between the hair bundles 11 other than 12b.

  Further, the shape of the butted end portions 12a and 12b can be other than the inclined plane as long as it is a shape that can be contacted without causing a gap when the end portions of the brush base portion 12 are butted, for example. Further, in this example, the abutting end portions 12a and 12b are planes parallel to the base end-tip direction, but other shapes may be used.

  As shown in FIGS. 1 to 3, the rail 22, the holder 23, and the movable member 21 are combined, so that the rail support portion 213 b (more specifically, the fixed portion 213 is supported by using the brush support portion 22 b of the rail 22 as a fulcrum. The fulcrum part 213b1) is supported, and the holder corresponding part 213a of the fixed part 213 is locked by the movable member corresponding part 23a of the holder 23 so that the position can be changed. In this way, the angle of the movable member 21 and the brush body 1 can be adjusted. The locking position is determined by the ridge 213 a 3 of the movable member 21 and the groove 23 a 1 of the holder 23. The locking position in this example is set per one locking (angle α = 15 degrees) between the ridge 213a3 of the movable member 21 and the groove 23a1 of the holder 23, and the angle adjustable range is the brush support portion 22b. The center is 75 degrees (for 6 locks). As described above, the boundary portion between the holder-corresponding portion 213a and the rail-corresponding portion 213b of the fixed portion 213 is formed to have a thin plate thickness (in a groove shape), and this can exhibit elasticity, so that the angle adjustment described above can be performed. The transition of the engagement between the ridges 213a3 and the concave grooves 23a1 can be made smoothly, and the movable member 21 can be easily rotated.

  In this example, the movable member 21 is provided with a ridge 213a3, and the holder 23 is provided with a concave groove 23a1, but conversely, the movable member 21 is provided with a concave groove and the holder 23 is provided with a ridge. It may be what was made. In addition, at least one of the materials of the mounting member 21 and the holder 22 is changed to a material having a large friction coefficient such as rubber (or surface coating may be used), and the engagement position is changed by friction to change the angle at a free stop. Adjustments are also possible.

  Since the angle can be adjusted as described above, the brush body 1 of the gap brush can be freely angled, which is advantageous in that it is not limited by the mounting location. For example, when the gap brush is attached to the building opening, as shown on the upper side of FIG. 5, in the state where the brush body 1 is laid without being inclined, the building-side attachment surface to which the rail 22 is attached The direction in which the brush body 1 extends can be made parallel. Further, as shown in the lower side of FIG. 5, when the brush body 1 is angled, the building-side mounting surface to which the rail 22 is attached and the direction in which the brush body 1 extends can be angled. For example, the tip of the brush body 1 can be in contact with the floor surface 57.

  The attachment of the gap brush of this example to the shutter used to open and close the building opening will be described below.

  As a general shutter structure, as shown in FIGS. 5 to 7, the opening is opened and closed. The shutter plate 51 is a combination of a plurality of strip-shaped metal plates, and the shutter is closed when the opening is closed. The guide rail 52 and the middle pillar 53 (installed as necessary) for supporting the left and right ends of the plate 51, a case for storing the shutter plate 51 above the opening when opened, a mechanism for driving the shutter plate 51, etc. However, since the structure of the shutter is known, detailed description thereof is omitted.

  In this example, the lintel portion 54 which is an entrance / exit of the shutter plate 51 provided under the case, the guide rail 52, the middle column 53, the seat plate portion 55 where the shutter plate 51 contacts the floor surface 57, and the above-described case. A gap brush is attached to the wall 56 of the building in which the guide rail is embedded. Further, in this example, the gap brush is attached to the outside of the opening of the shutter plate 51, but conversely, it may be attached to the inside.

  First, the attachment method in the case shown in FIG. 5 will be described. In the illustrated example, a rail 22x formed by integrating the rail 22 and the holder 23 is used. The building side fixing portion 22xa is attached with screws S so that the outer side (left side in the drawing) lintel portion 54 which is the entrance / exit of the shutter plate 51 comes into contact. The angle of the movable member 21 is adjusted using the angle adjusting function of the movable member 21 and the rail 22x so that the surface of the lintel 54 to which the rail 22x is attached and the direction in which the brush extends are parallel. Thereby, the clearance gap between the shutter board 51 and the lintel part 54 can be block | closed by making the front-end | tip of the bristle bundle 11 of the brush main body 1 contact | abut to the shutter board 51 perpendicularly.

  Further, the mounting side fixing portion 22xa of the rail 22x is attached to the outside of the seat plate portion 55 below the shutter so that the building side fixing portion 22xa abuts against the seat plate portion 55. Then, the angle of the movable member 21 is adjusted so that the tip of the hair bundle 11 of the brush body 1 is brought into contact with the floor surface 57 when the shutter is closed by using the angle adjusting function by the movable member 21 and the rail 22x. Thereby, the clearance gap between the seat board part 55 and the floor surface 57 can be block | closed.

  Next, the attachment method in the case shown in FIG. 6 will be described. In this example, the same rail 22x as the above example and the rail 22 and the holder 23 are integrally formed as in the above example, but the rail 22y having a different shape from the above example is used. ing. The rail 22y is provided with a building-side fixing portion 22ya extending further rearward than the rear holder attaching / detaching portion 22yak as described below.

  Here, the guide rail 52 that supports the shutter plate 51 includes an embedded type embedded in a building wall 56 as shown in FIG. 6A, and a building wall as shown in FIG. 6B. There is an exposed type exposed from 56. In the case of the embedded type, the attachment side fixing portion 22xa of the rail 22x is attached to the outer wall 56 in which the guide rail 52 is embedded so that the building side fixing portion 22xa contacts the wall 56. On the other hand, in the case of the exposed type, the attachment side fixing portion 22ya of the rail 22y is attached to the outer guide rail 52 so that the building side fixing portion 22ya contacts the guide rail 52. Then, the angle of the movable member 21 is adjusted so that the hair bundle 11 of the brush body 1 is brought into contact with the shutter plate 51 when the shutter is closed by using an angle adjusting function by the movable member 21, the rail 22x or the rail 22y. As a result, the gap between the shutter plate 51 and the guide rail 52 can be closed.

  Finally, the attachment method in the case shown in FIG. 7 will be described. In this example, the rail 22y in which the building side fixing | fixed part 22ya was formed is used similarly to said example. In addition to the guide rails 52 provided at both ends of the opening, a middle column 53 provided between the plurality of shutter plates 51 is used for the shutter provided in the wide opening. In this case, the attachment side fixing portion 22ya of the gap brush rail 22y is attached to the outside of the middle column 53 so that the building side fixing portion 22ya contacts the middle column 53. The angle of the movable member 21 is adjusted so that the hair bundle 11 of the brush body 1 is brought into contact with the shutter plate 51 when the shutter is closed by using the angle adjusting function by the movable member 21 and the rail 22y. Thereby, the gap between the shutter plate 51 and the middle pillar 53 can be closed.

  As described above, as an embodiment according to the present invention, the explanation has been made that the gap brush is attached to the opening for building, but it can also be applied to openings other than buildings (for example, openings of ships and trucks). is there. In addition, the gap brush of the present application can be attached by freely selecting the attachment position to the building, such as up and down, left and right, or diagonally.

  Next, an example of a more preferable embodiment as an improved example will be described (see FIG. 8).

  At the tip of the front holder attaching / detaching portion 22aj provided on the rail 22, there is an engaging fulcrum portion 22aj2. The engagement fulcrum portion 22aj2 serves as a fulcrum when the rail 22 and the holder 23 are disengaged using a screwdriver or a coin as a removal tool. Further, the “U” -shaped inner side surface 22aj3 of the front holder attaching / detaching portion 22aj is curved so that the cross-sectional shape is recessed outward, so that the removal tool can be easily guided to the rail 22 and the holder 23. ing. The inner side surface 22aj3 is not limited to this, and may have any shape such as a linear shape connecting the distal end side and the proximal end side of the curved shape as long as there is no problem in releasing the engagement. .

  The rear holder attaching / detaching portion 22ak is provided with a contact portion 22ak2. The contact portion 22ak2 is provided outside the “U” shape so as to protrude in the left-right direction, and in this example, forms a rectangular plate. The abutting portion 22ak2 abuts on the movable member 21 (more specifically, the portion of the rail corresponding portion 213b of the movable member 21 that is closer to the tip than the fulcrum portion 213b1). Restrict. The end surface of the contact portion 22ak2 is angled from the front end side to the base end side of the rear holder attaching / detaching portion 22ak so that the end portion of the rail corresponding portion 213b of the movable member 21 can easily come into contact with the front end portion of the fulcrum portion 213b1. ing. The contact position between the end surface of the contact portion 22ak2 and the movable member 21 is the lower limit of the rotation region of the movable member 21. In this example, the adjustable angle range is 45 degrees (for 4 engagements) with the brush support portion 22b as the center. This is because the rotation region is narrower than the example of the above-described embodiment, but the strength is maintained by keeping the rotation region in which the engagement between the holder 23 fitted in the rail 22 and the movable member 21 can be surely performed. And durability can be improved.

  In addition, the holding portion 22ak1 provided in the rear holder attaching / detaching portion 22ak is thicker toward the inside of the “U” shape, thereby strengthening the engagement with the holder 23 so that the holder 23 does not come out upward. ing.

  Further, the shape of the front rail attaching / detaching portion 23bi provided in the holder 23 is changed in order to make it easier to disengage the rail 22 and the holder 23 from each other. Specifically, the lower end portion 23bi1 of the front rail attaching / detaching portion 23bi in FIG. 8 contacts the building-side fixing portion 22ai of the rail 22, and the side portion 23bi2 of the front rail attaching / detaching portion 23bi protruding forward in FIG. 8 becomes the front holder attaching / detaching portion 22aj. By making contact, the front rail attaching / detaching portion 23bi of the holder 23 is engaged with the front holder attaching / detaching portion 22aj of the rail 22.

  Further, the front rail detachable portion 23bi is provided with an engaging action portion 23bi4 on the tip side from the side portion 23bi2 projecting forward of the front rail detachable portion 23bi, and the engaging action portion 23bi4 is formed with unevenness for preventing slipping. ing. When the engagement between the rail 22 and the holder 23 is released, the distal end of the removal tool is brought into contact with the engagement portion 23bi4, and the proximal end side of the tool is brought into contact with the engagement fulcrum portion 22aj2 serving as a fulcrum. And can be removed more easily using the lever principle. At this time, the unevenness formed in the engaging action portion 23bi4 prevents the tool from slipping when the engagement is released.

  The brush is supported inside the intermediate portion on the proximal end side and the distal end side of the front holding portion 211a provided in the holding portion 211 of the movable member 21, and on the inner side of the proximal end side and the distal end side of the rear holding portion 211b. A protrusion having a semicircular cross section extending in the left-right direction is provided. The middle projection of the front holding portion 211a is the front middle projection 211at3, and the middle projection of the rear holding portion 211b is the rear middle projection 211bt3. The front intermediate protrusion 211at3 and the rear intermediate protrusion 211bt3 are paired in the front-rear direction, and both support the intermediate portion of the brush base 12. The front base end protrusion 211at1 and the rear base end protrusion 211bt1, the front front end protrusion 211at2 and the rear front end protrusion 211bt2, and the front intermediate protrusion 211at3 and the rear intermediate protrusion 211bt3 support the brush base 12, respectively. 1 is held by the movable member 21, but the front intermediate portion protrusion 211at3 and the rear intermediate portion protrusion 211bt3 are not necessarily provided in the front holding portion 211a and the rear holding portion 211b.
