JP 2005-24223 A JP 2010-60210 A JP 2014-77612 A

  However, all disclosed in Patent Documents 1-3 integrally form a pair of fixed locking claws that are locked to the refrigerant tubes of the two heat exchangers with respect to the windshield body. The pair of locking claws are locked to the refrigerant tube by elastically deforming the fixed type locking claws, the wind shielding plate body, or the elastic portion provided on the wind shielding plate body. In this case, the installation strength of the wind shielding plate depends on the size of the engaging margin of the fixed type locking claw.

  For this reason, if the engagement amount of the locking claw is increased in order to secure the installation strength, a large force is required to deform the locking claw, the windshield body or the elastic portion provided on the windshield body. This not only makes it difficult to install the windshield, but also increases the risk of breakage of the locking claws. Accordingly, the size of the engaging claw of the locking claw with respect to the refrigerant tube is naturally limited, and there arises a problem that the windshield plate is easily detached when an impact force is applied from the outside, and a clip of another part is used. In some cases, measures were taken such as holding the windshield.

  In addition, in the case of a windshield plate provided with fixed locking claws on the windshield plate body, when installing the windshield plate on the heat exchanger supported by inserting the hairpin tube portions at both ends into the bracket, If a locking claw is provided near the end of the windshield, the locking claw will interfere with the fins of the heat exchanger when one end of the windshield is inserted into the bracket. It is necessary to provide a locking claw at a position away from one end of the plate by a certain distance. For this reason, there also existed problems, such as being unable to arrange | position a latching claw in the optimal position in order to ensure the installation intensity | strength of a windshield.

  The present invention has been made in view of such circumstances, and the windshield plate installed in the top gap between the heat exchangers arranged in a V shape or an inverted V shape is subjected to an impact from the outside. The purpose of the present invention is to provide an air conditioner that can ensure the ease of installation even if the engaging claw of the locking claw is sufficiently large to ensure the installation strength so that it does not come off even if force is applied. To do.

In order to solve the above-described problems, the air conditioner of the present invention employs the following means.
That is, the air conditioner according to the present invention includes a plate fin tube type first heat exchanger and a second heat exchanger arranged in a V shape or an inverted V shape in the ventilation path, and the first heat. Provided in a gap between one end portions of the exchanger and the second heat exchanger, and provided in a plurality of locations in the longitudinal direction of the main body of the windshield plate, and a windshield plate for shielding the gap. A pair of locking claws that are locked to the refrigerant tubes of the heat exchanger and the second heat exchanger and fix the windshield plate to the first heat exchanger and the second heat exchanger. One of the locking claws is a movable claw integrally formed so as to be rotatable with respect to the wind shielding plate body.

  According to the present invention, the windshield plate is provided in the windshield body that winds the gap between the one end portions of the first heat exchanger and the second heat exchanger, and is locked to the refrigerant tube of both heat exchangers. Since one of the pair of locking claws that fix and install is a movable claw that is integrally formed so as to be rotatable with respect to the windshield plate body, when the windshield plate is installed, one of the movable claws is placed in the non-locking position. In the rotated state, after the other locking claw is locked to the refrigerant tube of one heat exchanger, the movable claw is rotated and locked to the refrigerant tube of the other heat exchanger, so that a pair of The wind shield plate can be fixedly installed between the first and second heat exchangers via the locking claws. In addition, when installing the wind shield, if a fixing claw is provided near the end of the wind shield against the heat exchanger whose both ends are inserted and supported by the bracket, one end of the wind shield is inserted into the bracket. When inserting, the fixed claw interferes with the heat exchanger, making it difficult to insert, but if one is a movable claw, even if a locking claw is provided near the end of the windshield, the movable claw The windshield plate can be easily installed by inserting it into the bracket in a state where it is rotated to a position where it avoids interference with the heat exchanger. Therefore, compared to a pair of locking claws with fixed claws, it is possible to fix and install the wind shield plate firmly with a larger locking allowance of the locking claws, and a wind shield plate due to externally applied impact force, etc. Can be reliably prevented, and the degree of freedom of arrangement of the locking claws provided at a plurality of locations in the length direction of the wind shield body is ensured, and the locking claws are arranged at the optimum positions to block the windshield plate. The installation strength of the wind plate can be further increased.

  Furthermore, the air conditioner of the present invention is the above air conditioner, wherein when the movable claw is locked to the refrigerant tubes of the first heat exchanger and the second heat exchanger, the movable claw A fixed claw for locking the movable claw to the locking position by locking to the windshield body is integrally provided.

  According to the present invention, when the movable claw is locked to the refrigerant tube of the first heat exchanger or the second heat exchanger, the movable claw is locked to the wind shielding plate body. Since the fixed claw for fixing to the position is integrally provided, when the movable claw is rotated and locked to the refrigerant tube of the first heat exchanger or the second heat exchanger, the fixed claw is provided integrally with the movable claw. When the fixed claw is locked to the wind shielding plate main body, the movable claw can be fixed at the locking position with respect to the refrigerant tube, and its rotation can be made immovable. Therefore, once the windshield plate is installed between the first heat exchanger and the second heat exchanger, the movable claw is integrated with the windshield plate main body. The windshield plate can be fixedly installed more firmly.

  Furthermore, the air conditioner of the present invention is the air conditioner described above, wherein either one of both side end surfaces of the fixed claw or both side end surfaces of the fitting portion of the windshield main body to which the fixed claw rotates is fitted. In addition, the fixed claw is provided with a return prevention protrusion.

  According to the present invention, the return protrusions of the fixed claw are provided on either side end surfaces of the fixed claw or both side end surfaces of the fitting portion of the windshield main body to which the fixed claw rotates and is fitted. Therefore, when the fixed claw is rotated to the locking position with respect to the windshield body along with the rotation of the movable claw, the return prevention protrusions provided on the both end faces of the fixed claw are the windshield body. Overcoming the both end surfaces of the fitting part of the fixed claw, or by rotating the both end faces of the fixing claw over the return prevention protrusions provided on the both end surfaces of the fitting part of the windshield body, The protrusion can prevent the fixed claw from returning. Therefore, when the fixed claw is locked to the windshield main body and the movable claw is integrated with the windshield main body, the fixed claw is prevented from returning and the state is reliably fixed, thereby preventing the shield. A strong fixed installation of the wind plate can be stably maintained.

  In the air conditioner of the present invention, in any one of the above air conditioners, the movable claw is integrally formed with the windshield body through a hinge portion that is partially thin. Features.

  According to the present invention, since the movable claw is integrally formed with the windshield body through the hinge portion that is partially thinned, the movable claw is attached via the hinge portion that is partially thinned. The windshield body can be rotated with respect to the windshield body, and even if a large engagement allowance is set for the movable claws, the windshield board body can be turned easily without turning the windshield board body with a large force. It can be locked to the refrigerant tube of the exchanger. Accordingly, it is possible to facilitate the installation of the wind shielding plate while increasing the engagement allowance as compared with the fixed claw.

  Moreover, the air conditioner of the present invention is characterized in that, in any of the above-described air conditioners, the wind shielding plate is an integrally molded product made of PP resin including the movable claws.

  According to the present invention, since the windshield plate is an integrally molded product made of PP (polypropylene) resin including the movable claw, PP (polypropylene) resin is lightweight and high in strength, particularly strong against repeated bending, Because of its excellent hinge characteristics, it is ideal for windshields that have movable claws that can be rotated through the hinge part. The installation strength of the windshield can be ensured.

  According to the present invention, when the windshield plate is installed, after the one movable claw is rotated to the non-locking position and the other locking claw is locked to the refrigerant tube of the one heat exchanger, the movable claw The wind shield plate can be fixedly installed between the first and second heat exchangers via a pair of latching claws by rotating and locking to the refrigerant tube of the other heat exchanger. In addition, when installing the wind shield, if a fixing claw is provided near the end of the wind shield against the heat exchanger whose both ends are inserted and supported by the bracket, one end of the wind shield is inserted into the bracket. When inserting, the fixed claw interferes with the heat exchanger, making it difficult to insert, but if one is a movable claw, even if a locking claw is provided near the end of the windshield, the movable claw Since it can be easily installed by inserting the wind shield plate into the bracket in a state where it has been rotated to a position that avoids interference with the heat exchanger, it is easier to install than a pair of locking claws. The windshield plate can be fixed and installed with a larger locking allowance for the pawl, and it is possible to reliably prevent the windshield plate from coming off due to impact force applied from the outside. Ensuring the freedom of arrangement of the locking claws provided at multiple locations in the length direction, Installation intensity of wind shield plate by placing position can be further improved.

In addition, a plurality of vertical louvers (louvers) 22 that adjust the airflow direction of the temperature-controlled air blown out from the air outlet 14 in the left-right direction are rotatably disposed in the air-blowing grill 7. A horizontal flap (flap) 23 that adjusts the wind direction in the vertical direction is rotatably disposed.

  The indoor heat exchanger 17 is divided into the first heat exchanger 17A disposed on the front surface side and the second heat exchanger 17B disposed on the rear surface side as described above, and is placed in the ventilation path in the housing 2. Although it is divided and bent into an inverted V shape from the lower part of the front surface to the upper surface and the rear surface side, a predetermined gap is set between the upper ends of the first heat exchanger 17A and the second heat exchanger 17B. The gap is shielded by the wind shield 24 so that the air flow bypasses the indoor heat exchanger 17 and does not flow downstream.

  As shown in FIGS. 3 to 9, the wind shielding plate 24 has a width dimension across the upper end portions of the first heat exchanger 17 </ b> A and the second heat exchanger 17 </ b> B and a length dimension of the indoor heat exchanger 17. A windshield plate body 25 made of an elongated thin plate material having substantially the same lengthwise dimension, and a plurality of pairs of front and rear locking claws 26 and 27 provided at a plurality of locations in the longitudinal direction of the windshield plate body 25; And a pair of front and rear second locking claws 28, 29 provided on the end face on one end side of the wind shield body 25, and the locking claws 26, 27 and the second locking claws 28, 29. Is fixedly installed by being locked to the refrigerant tubes 17C of the first heat exchanger 17A and the second heat exchanger 17B.

  The windshield body 25 is curved so that the front edge 25A side in the length direction covers the upper end surface of the first heat exchanger 17A, while the rear edge 25B side is the upper end surface of the second heat exchanger 17B. The upper surface of the first heat exchanger 17A and the second heat exchanger 17B is fixedly installed between the first heat exchanger 17A and the second heat exchanger 17B so that the upper surface is 5 toward the second heat exchanger 17B. It is designed to be inclined obliquely downward. Further, slit-like drain holes 30 are provided at a plurality of locations along the length direction of the lowest position on the inclined upper surface to drain the drain water condensed on the surface of the wind shielding plate 24 onto the second heat exchanger 17B. It is set as the structure.

  Further, the pair of front and rear second locking claws 28 and 29 provided on the end surface on one end side in the length direction of the wind shielding plate body 25 are refrigerants of the first heat exchanger 17A and the second heat exchanger 17B, respectively. It is set as the bifurcated latching claw fitted by fitting in the tube 17C. The other end in the length direction of the windshield body 25 is fixed by inserting the other end into a heat exchange support bracket (not shown) that supports the end of the indoor heat exchanger 17. There are no nails.

  Furthermore, it is provided at a plurality of locations in the length direction of the windshield main body 25 (5 locations in the present embodiment) at substantially equal intervals, and is respectively provided in the refrigerant tubes 17C of the first heat exchanger 17A and the second heat exchanger 17B. Of the pair of front and rear locking claws 26 and 27 to be locked, the locking claw 26 on the front edge 25A side is a fixed claw, but the locking claw 27 on the rear edge 25B side is rotatable. The movable claw (hereinafter also referred to as a movable claw 27) is used. The plurality of sets of locking claws 26, 27, second locking claws 28, 29, and drainage holes 30 are integrally formed with the windshield body 25 including the movable claws 27.

  The movable claw 27 on the rear edge 25B side that constitutes the pair of locking claws 26, 27 is a rear edge portion of the cut-and-raised portion 31 that is shaped like a cut-out portion on the rear edge 25B side of the windshield plate body 25. 4 and 9, a hook portion 33 is integrally provided with a hook-shaped claw 32. As shown in FIGS. 4 and 9, the connecting portion with the windshield body 25 is partially thinned through a hinge portion 33. They are connected together. The wind shield plate 24 is a light-weight, high-strength, particularly-resistant molded product made of PP (polypropylene) resin that is strong against repeated bending and excellent in hinge characteristics. The hinge function of the portion 33 is secured.

  Further, a stepped portion 34 is provided at a position on the tip end side by a predetermined dimension from the hinge portion 33 of the cut and raised portion 31, and the stepped portion 34 is provided on the lower surface side of the wind shielding plate body 25 (see FIGS. 4 and 5). In the state where the cut-and-raised portion 31 shown in FIG. 9 is raised, a fixed claw 35 protruding in the right direction in the figure is integrally provided. When the movable claw 27 is rotated from a position where the movable claw 27 stands upward as shown in FIGS. 4 and 9 to a position where the movable claw 27 is engaged with the refrigerant tube 17C of the second heat exchanger 17B, The movable claw 27 is made unmovable by being locked to the end of a notch fitting portion (fitting portion) 36 provided on the plate body 25 side, and the movable claw 27 is fixed at that position and blocked. It is in a state of being integrated with the wind plate body 25.

  On the left and right end faces of the fixed claw 35, the movable claw 27 is rotated to a position where it is locked to the refrigerant tube 17C, so that the fixed claw 35 is locked to the end of the notch fitting portion 36. When rotated, there are provided return-preventing projections 37 that interfere with both end faces of the notch fitting portion 36 and prevent the fixed pawl 35 from returning from that position. The return prevention protrusions 37 may be provided on both side end surfaces of the notch fitting portion 36 so that the return prevention protrusions interfere with the fixed claws 35 and prevent the fixed claws 35 from returning.

  Furthermore, a pair of pin portions 38 projecting to the left and right sides are provided on the left and right side end surfaces of the step portion 34 on the side opposite to the fixing claw 35, and pin fitting for fitting the pair of left and right pin portions 38 is provided. The joint portion 39 is integrally provided on the windshield plate body 25 on the left and right sides of the notch fitting portion 36. When the movable claw 27 is rotated to a position where the movable claw 27 is locked to the refrigerant tube 17C, the pin portion 38 and the pin fitting portion 39 are fitted to the pin fitting portion 39, so that the movable claw 27 is the same. It is for stably fixing and holding the position.

With the configuration described above, according to the present embodiment, the following operational effects can be obtained.
When the air conditioner 1 starts operation, the cross flow fan (blower fan) 18 is rotated by the motor. As a result, indoor air is sucked into the housing 2 via the suction grill 12 and the suction port 13. The air sucked into the housing 2 is purified by the air filter 15 and the air purification filter 16, and then enters the indoor heat exchanger 17 including the plurality of first heat exchangers 17 </ b> A and second heat exchangers 17 </ b> B. It is ventilated and cooled or heated by exchanging heat with the refrigerant in the indoor heat exchanger 17.

  The temperature-controlled air is energized by a cross flow fan (blower fan) 18 and is blown into the room from the blowout port 14 through the ventilation path 20 and the blowout flow path 20A to be used for indoor air conditioning. The temperature-controlled air blown into the room is blown toward an arbitrary area with the wind direction adjusted by a vertical louver (louver) 22 and a horizontal flap (flap) 23 provided at the air outlet 14.

  During this time, the wind shield 24 fixedly installed between the upper ends of the first heat exchanger 17A and the second heat exchanger 17B allows the room air to bypass the indoor heat exchanger 17 through the gap between the upper ends. This prevents the air from flowing, and eliminates adverse effects such as deterioration of the air conditioning feeling caused by the non-temperature-controlled air being mixed with the temperature-controlled air that has passed through the indoor heat exchanger 17 and blown out. Further, during the cooling operation, the indoor heat exchanger 17 functions as an evaporator, and in this case, there is a possibility that dew condensation may occur on the surface of the wind shielding plate 24 that is cooled via the indoor heat exchanger 17. The drain water flows to the second heat exchanger 17B side along the inclined surface of the upper surface of the wind shielding plate 24, and is discharged onto the second heat exchanger 17B through the drainage hole 30, whereby the back side drain pan 8 is discharged. Will be led to.

  On the other hand, the wind shield plate 24 includes a pair of front and rear locking claws 26 provided in a plurality of locations in the length direction in the gap between the upper ends of the first heat exchanger 17A and the second heat exchanger 17B. 27, the first and second heat exchangers 17 </ b> A and 17 </ b> B are fixedly installed by being locked to the refrigerant tubes 17 </ b> C. Since the structure is integrally formed so as to be rotatable with respect to the windshield main body 25, specifically, it is fixedly installed by the following procedure.

  The windshield plate 24 has one end of the windshield plate body 25 on the side where the latching claws are not provided inserted into a heat exchange support bracket (not shown), and a pair of second latching claws 28 and 29 on the other end side. Is fitted to the refrigerant tube 17C at the other end of the first heat exchanger 17A and the second heat exchanger 17B. At this time, a pair of engagement members provided at a plurality of locations in the length direction are assembled. As shown in FIGS. 4 and 8-9, the first pawls 26 and 27 are first bent on the front edge 25A side of the windshield body 25 in the curved shape of the windshield body 25 in a state where the movable pawls 27 stand upward as shown in FIGS. The locking claw 26 is locked to the refrigerant tube of the first heat exchanger 17A so as to cover the upper end portion of the first heat exchanger 17A, and the inclined surface on the rear edge 25B side of the windshield body 25 is subjected to the second heat exchange. The container 17B is brought into contact with the upper end surface. This state is shown in FIG.

  Next, the cut-and-raised portion 31 of the movable claw 27 standing upward is rotated backward from the hinge portion 33 toward the substantially horizontal position and fitted into the cut-out fitting portion 36 to thereby move the movable claw. The claw 32 having the 27 hook shape is engaged with the refrigerant tube 17C of the second heat exchanger 17B. Then, as described above, by rotating the movable claw 27 so as to be fitted into the notch fitting portion 36, the return prevention protrusions 37 provided on the left and right end surfaces of the fixed claw 35 are notched fitting portions. The fixed claw 35 is rotated downward so as to exceed both side end surfaces of 36 or return return projections provided on both side end surfaces of the notch fitting portion 36.

  As a result, the fixed claw 35 is locked to the end portion of the notch fitting portion 36 provided on the windshield plate body 25, the rotation of the movable claw 27 is made immovable, and the movable claw 27 is fixed at that position. Thus, the windshield body 25 is integrated with the windshield body 25. The fixing claws 35 are provided so that the return-preventing projections 37 provided on the left and right side end surfaces exceed the both side end surfaces of the notch fitting portion 36 or on the both side end surfaces of the notch fitting portion 36. Since the fixing claw 35 is pivoted downward so as to exceed the blocking projection 35, the reverse rotation is blocked by the return blocking projection 37. Therefore, the movable claw 27 can be securely held at the position locked to the refrigerant tube 17C of the second heat exchanger 17B.

  Further, when the movable claw 27 is rotated to a position where it is locked to the refrigerant tube 17C of the second heat exchanger 17B, both the left and right sides provided on the left and right side end surfaces of the stepped portion 34 position of the cut-and-raised portion 31 are provided. The pair of pin portions 38 protruding in the direction can be stably fixed and held at the locking position by being fitted into the pin fitting portion 39 integrally provided on the upper surface of the windshield plate body 25. It has become.

  Thus, according to the present embodiment, the refrigerant is provided in the wind shielding plate 24 that shields the gap between the one end portions of the first heat exchanger 17A and the second heat exchanger 17B, and the refrigerant of both the heat exchangers 17A and 17B. One of the pair of locking claws 26 and 27 that fix and install the windshield plate 24 by being locked to the tube 17C is a movable claw 27 that is integrally formed with the windshield plate body 25 so as to be rotatable. Therefore, when installing the wind shielding plate 24, the other locking claw 26 is locked to the refrigerant tube 17C of the first heat exchanger 17A while the one movable claw 27 is rotated to the non-locking position. Thereafter, the movable claw 27 is rotated and locked to the refrigerant tube 17C of the other second heat exchanger 17B, whereby the wind shielding plate 24 is connected to the first and second via the pair of locking claws 26, 27. It can be fixedly installed between the heat exchangers 17A and 17B.

  Further, when the windshield plate 24 is assembled, if a locking claw fixed near the end portion of the windshield plate 24 is provided to the indoor heat exchanger 17 whose both ends are inserted and supported by the support bracket, the shield plate 24 is provided. When one end of the wind plate 24 is inserted into the support bracket, the fixed latching claw interferes with the fins of the indoor heat exchanger, making it difficult to insert. Even when the locking claws 26 and 27 are provided near the end of the plate 24, the heat shield support is provided for the wind shield plate 24 in a state where the movable claw 27 is rotated to a position to avoid interference with the second heat exchanger 17B. It can be easily installed by inserting it into the bracket.

  Therefore, the windshield plate 24 can be fixedly installed firmly by increasing the engaging margin of the locking claws 26 and 27 as compared with a pair of locking claws 26 and 27 having a fixed structure. Therefore, it is possible to reliably prevent the windshield plate 24 from coming off due to an impact force applied from the outside due to a collision or a drop during transportation / conveyance, and the windshield plate body 25 is provided at a plurality of locations in the length direction. The installation strength of the wind shielding plate 24 can be further increased by securing the degree of freedom of the arrangement of the locking claws 26 and 27 and arranging the locking claws 26 and 27 at the optimum positions.

  Further, when the movable claw 27 is locked to one refrigerant tube 17C of the divided first heat exchanger 17A or second heat exchanger 17B of the indoor heat exchanger 17, the movable claw 27 is shielded from wind. Since the fixed claw 35 that locks the plate main body 25 and fixes the movable claw 27 in the locked position is integrally provided, the movable claw 27 is rotated to rotate the first heat exchanger 17A or the second heat exchange. When the fixed claw 35 provided integrally with the movable claw 27 is locked to the wind shielding plate body 25 when locked to the refrigerant tube 17C of the vessel 17B, the movable claw 27 is locked to the refrigerant tube 17C. The position can be fixed and the rotation can be made immovable.

  As a result, once the windshield 24 is installed between the first heat exchanger 17A and the second heat exchanger 17B, the movable claw 27 is integrated with the windshield main body 25. The wind shielding plate 24 can be fixedly installed in the gap between the first heat exchanger 17A and the second heat exchanger 17B with a margin.

  Furthermore, according to the present embodiment, either the both side end surfaces of the fixed claw 35 or the both side end surfaces of the notch fitting portion (fitting portion) 36 of the wind shielding plate body 25 to which the fixed claw 35 is rotated and fitted. In addition, a protrusion 37 for preventing return of the fixed claw 35 is provided. For this reason, when the movable claw 27 is rotated, when the fixed claw 35 is rotated to the locking position with respect to the wind shielding plate body 25, the return prevention protrusions 37 provided on both side end surfaces of the fixed claw 35 are blocked. Overcoming both side end surfaces of the notch fitting portion 36 of the wind plate main body 25 or both side end surfaces of the fixing claw 35 are provided on both side end surfaces of the notch fitting portion 36 of the wind shielding plate main body 25. The return claw 35 can prevent the return of the fixed claw 35 by turning over the rotation.

  Thus, when the fixed claw 35 is locked to the windshield main body 25 and the movable claw 27 is integrated with the windshield main body 25, the fixed claw 35 is prevented from returning and the state is ensured. By fixing, the firm fixing installation of the wind shielding plate 24 can be held more stably.

  Further, since the movable claw 27 is integrally formed with the wind shielding plate body 25 via the hinge portion 33 which is partially thinned, the movable claw is interposed via the hinge portion 33 which is partially thinned. 27 can be rotated with respect to the windshield plate body 25, and even if a large engagement allowance is set for the movable claw 27, the movable claw 27 can be turned without bending the windshield plate body 25 with a large force. It can be easily locked to the refrigerant tube 17C of the first or second heat exchanger 17A, 17B. Therefore, the installation itself of the wind shielding plate 24 can be facilitated while increasing the engagement allowance compared to the fixed structure claw.

  Further, since the wind shield 24 is an integrally molded product made of PP (polypropylene) resin including the movable claw 27, PP (polypropylene) resin is lightweight and high in strength, particularly resistant to repeated bending, and has hinge characteristics. Therefore, it is most suitable for the wind shield plate 24 having the movable claw 27 that can be rotated via the hinge portion 33, and the high-strength wind shield that integrally forms the rotatable movable claw 27. It can be set as the board 24, and the installation intensity | strength of the windshield 24 can be ensured.

  In addition, this invention is not limited to the invention concerning the said embodiment, In the range which does not deviate from the summary, it can change suitably. For example, in the above-described embodiment, an example in which the first heat exchanger 17A and the second heat exchanger 17B are arranged in an inverted V shape in the ventilation path 20 has been described. Of course, the present invention can be similarly applied to an air conditioner arranged in a letter shape.

  Moreover, in the said embodiment, although one latching claw 27 of the pair of latching claws 26 and 27 provided in the wind-shielding plate 24 is the movable claw 27 which can be rotated, the latching claw 27 is a fixed structure. Needless to say, a claw and the other locking claw 26 may be a freely movable claw.
