[0009] (Embodiment 1) Hereinafter, an embodiment will be described with reference to the drawings. In the following description, arrows in the drawings will be used to indicate left and right, front and rear, and up and down. FIG. 1 is a perspective view of an open-cabin type vehicle 8 according to the first embodiment. FIG. 2 is a perspective view showing a frame 9 on which an air conditioner 92 is mounted attached to a support 81 by a fixture 1. The open-cabin type vehicle 8 to which the air conditioner 92 of this embodiment is attached will be described. One example of the open-cabin type vehicle 8 of this embodiment is a forklift. Alternatively, the open-cabin type vehicle 8 may be a construction machine or a work vehicle such as a small excavator. The forklift, which is the open-cabin type vehicle 8, has two support pillars 81 that support head guards. The frame 9, which will be described later, is rotatably attached to these two support pillars 81 by the fixture 1.

[0010] In this embodiment, the fixture 1 is attached to the left support pillar 81. The support pillar 81 includes a first side surface 811, a second side surface 812, a third side surface 813, and a fourth side surface 814. Based on the front, rear, left, and right directions of the open-cabin type vehicle 8, the first side surface 811 corresponds to the left side surface, the second side surface 812 corresponds to the rear side surface, the third side surface 813 corresponds to the front side surface, and the fourth side surface 814 corresponds to the right side surface. That is, the first side surface 811, the second side surface 812, the fourth side surface 814, and the third side surface 813 are positioned in that order counterclockwise. Therefore, the first side surface 811, which is the left side surface, faces the fourth side surface 814, which is the right side surface, and the second side surface 812, which is the rear side surface, faces the third side surface 813, which is the front side surface. When a horizontal axis intersecting the first side surface 811 is used as a reference, the first side surface 811 and the fourth side surface 814 correspond to planes perpendicular to the horizontal axis, and the second side surface 812 and the third side surface 813 correspond to planes parallel to the horizontal axis.

[0011] A clamp member similar to the fixture 1 is attached to the right support 81. A hinge portion 5 is attached to the fixture 1. A base 9 on which an air conditioner 92 is placed is fastened to the hinge portion 5. The base 9 includes a basket-shaped storage section for placing and storing the air conditioner 92, and a shaft 91 extending horizontally. The base 9 fastened to the hinge portion 5 is attached so that it can rotate around a vertical axis of rotation of the hinge portion 5. The end of the shaft 91 engages with a clamp member attached to the right-side support 81, thereby fixing the base 9.

[0012] FIG. 3 is a perspective view showing a state in which the pedestal 9 on which the air conditioner 92 is mounted is being rotated relative to the support column 81 by the fixture 1. By removing the shaft 91 of the pedestal 9 from the clamp member attached to the right-side support column 81, the restriction on the pedestal 9 is released, and the pedestal 9 can be rotated around the vertical axis. By rotating the pedestal 9, the pedestal 9 can be moved to a position on the trajectory of the rotation at the rear of the open-cabin type vehicle 8. This allows maintenance work, etc. to be performed around the seats of the open-cabin type vehicle 8. At this time, the weight of the pedestal 9 and the air conditioner 92 mounted on the pedestal 9 is applied to the fixture 1, and therefore, a clockwise stress is applied to the fixture 1 as viewed from the left. The application of this clockwise stress acts as a force that rotates the fixture 1 around a horizontal axis, but the rotation around the horizontal axis can be suppressed by the rotation suppressing member 6 included in the fixture 1.

[0013] Fig. 4 is a perspective side view showing a state in which a fixing device 1 including a rotation suppressing member 6 clamps a support pillar 81. Fig. 5 is an exploded perspective view showing a support member 2 including a first clamping member 21 and a second clamping member 22. Fig. 6 is a perspective view showing the rotation suppressing member 6. In this embodiment, the fixing device 1 is attached to a support pillar 81 on the left side of an open-cabin type vehicle 8. The support pillar 81 of the open-cabin type vehicle 8 is inclined forward. The fixing device 1 includes a support member 2 and a rotation suppressing member 6, and a hinge portion 5 is fastened to the support member 2.

[0014] The support member 2 includes a plate-shaped first clamping member 21 and a second clamping member 22. In the same support 81, the first clamping member 21 is arranged on the side of a first side surface 811, which is the left side surface of the support 81, and the second clamping member 22 is arranged on the side of a fourth side surface 814, which is the right side surface. Bolt holes 31 are formed in the four corners of the first clamping member 21 and the second clamping member 22.

[0015] The support pillar 81 is interposed between the first clamping member 21 and the second clamping member 22, and the bolts 3 are inserted into and fastened to the bolt holes 31 of the first clamping member 21 and the second clamping member 22, respectively, so that the support pillar 81 is clamped by the first clamping member 21 and the second clamping member 22. In this manner, the support member 2 functions as a clamp member that clamps the support pillar 81. At this time, the inner surface of the second clamping member 22 of the support member 2 fastened with the bolt 3 may come into contact with the third side surface 813 of the support pillar 81, thereby contributing to suppression of rotation of the support member 2 relative to the support pillar 81.

[0016] Although the support member 2 has been described as functioning as a clamp member by separate parts consisting of the first clamping member 21 and the second clamping member 22, the support member 2 is not limited to this. The support member 2 may be one in which the first clamping member 21 and the second clamping member 22 are integrally formed into a U-shape by an intermediate member positioned between the first clamping member 21 and the second clamping member 22.

[0017] A plurality of through holes 4 are formed in the first clamping member 21. The plurality of through holes 4 includes through holes 4 that are arranged at equal intervals in the width direction of the first side surface 811 of the support pillar 81, i.e., in the front-rear direction of the open-cabin type vehicle 8, when the first clamping member 21 is attached to the support pillar 81, and through holes 4 that are arranged in the up-down direction. In this embodiment, three through holes 4 are formed above and below the first clamping member 21, for a total of six through holes 4.

[0018] By forming a plurality of through holes 4 along the width direction of the first side surface 811 of the support pillar 81, it is possible to accommodate differences in the size or shape of the support pillar 81 depending on the type of open-cabin vehicle 8 by using any of the through holes 4. Furthermore, by inserting screws 7 into the two through holes 4 in the vertical direction, the rotation suppressing member 6 and the first clamping member 21 can be fixed at two locations, and the fixing force between the rotation suppressing member 6 and the first clamping member 21 can be improved.

[0019] A rotation suppressing member 6 is interposed between the first clamping member 21 and the support pillar 81. In this embodiment, a single rotation suppressing member 6 is disposed for each support pillar 81, and the rotation suppressing member 6 corresponds to a first L-shaped member 61. That is, the rotation suppressing member 6 includes the first L-shaped member 61. The first L-shaped member 61 has a first plate portion 611 and a second plate portion 612 formed by bending the first plate portion 611, and the first plate portion 611 and the second plate portion 612 form an L shape in a cross-sectional view from above. The first L-shaped member 61 further has a protrusion 63, which is formed by bending the first plate portion 611 in the opposite direction to the second plate portion 612.

[0020] The first plate portion 611 has a rectangular plate shape and is clamped between the first side surface 811 of the support 81 and the inner surface of the first clamping member 21, with its longitudinal direction aligned with the height direction of the support 81. That is, the left surface of the first plate portion 611 contacts the inner surface of the first clamping member 21, and the right surface of the first plate portion 611 contacts the first side surface 811 of the support 81. The second plate portion 612 has a rectangular plate shape and is formed by being bent toward the right with respect to the first plate portion 611. That is, the second plate portion 612 is connected to the first plate portion 611. Like the first plate portion 611, the second plate portion 612 has a rectangular plate shape and is in contact with the second side surface 812 of the support 81, with its longitudinal direction aligned with the height direction of the support 81.

[0021] The length of the second plate portion 612 in the longitudinal direction is equal to the length of the first plate portion 611 in the longitudinal direction. The length of the second plate portion 612 in the lateral direction is smaller than the length of the first plate portion 611 in the lateral direction, i.e., the area of ​​the second plate portion 612 is smaller than the area of ​​the first plate portion 611. The length of the lateral direction of the second plate portion 612 may be set to be between 70% and 95% of the width of the second side surface 812 of the support 81, such as 90% of the width of the second side surface 812 of the support 81. By setting the length of the lateral direction of the second plate portion 612 close to the width of the second side surface 812 of the support 81, the contact area between the second plate portion 612 and the second side surface 812 of the support 81 is increased, and the second plate portion 612 can effectively withstand stress in the clockwise direction due to the weight of the air conditioner 92 and the frame 9.

[0022] The protrusion 63 formed above the first plate portion 611 has a rectangular plate shape and is bent toward the left side relative to the first plate portion 611. The protrusion 63 is arranged with its longitudinal direction aligned with the width direction of the first side surface 811 of the support 81, i.e., the front-to-rear direction. The length of the protrusion 63 in the longitudinal direction is smaller than the length of the first plate portion 611 in the lateral direction. The length of the protrusion 63 in the lateral direction is equal to or greater than the thickness of the first clamping member 21, i.e., the dimensional value of the plate thickness.

[0023] The lower surface of the protrusion 63 is arranged in contact with the upper surface of the first clamping member 21, i.e., the protrusion 63 is located above the upper surface of the first clamping member 21. At this time, the length of the protrusion 63 in the short direction is equal to or greater than the thickness of the first clamping member 21, and therefore the protrusion 63 of the first L-shaped member 61 is locked onto the upper surface of the first clamping member 21. As a result, when the first plate portion 611 of the first L-shaped member 61 is interposed between the inner surface of the first clamping member 21 and the first side surface 811 of the support 81, the protrusion 63 is locked onto the upper surface of the first clamping member 21, thereby preventing the first L-shaped member 61 from falling.

[0024] As described above, a plurality of through holes 4 are formed in the first clamping member 21. A spiral groove is formed on the inner surface of each through hole 4, and the through hole 4 functions as an internal thread when a screw 7 is inserted into it. In this embodiment, three through holes 4 are formed on each of the upper and lower parts, and a screw 7 is inserted into each of the through holes 4 formed in the center in the front-to-rear direction on both the upper and lower parts.

[0025] FIG. 7 is a perspective view showing the screw 7 that secures the first clamping member 21 of the support member 2 and the rotation suppressing member 6. The screw 7 inserted into the through hole 4 may be a double-point screw with a conical protrusion formed at its tip. The tip of the double-point screw has a conical protrusion formed in the center of the tip of the recess. By inserting the double-point screw into the through hole 4, the conical protrusion formed at the tip of the screw 7 and the annular peripheral portion of the recess bite into the first plate portion 611 of the first L-shaped member 61, thereby increasing the frictional force between the screw 7 and the first L-shaped member 61.

[0026] In the screw 7, the length of the shank on which the spiral groove is formed is greater than the thickness of the first clamping member 21 included in the support member 2, and is less than the combined thickness of the first clamping member 21 and the rotation suppressing member 6. By using the screw 7 configured in this manner, the tip of the screw 7 inserted into the through hole 4 of the first clamping member 21 presses against the first plate portion 611 of the first L-shaped member 61, making it possible to firmly fix the first L-shaped member 61 to the support member 2.

[0027] As shown in the present embodiment, when the support pillar 81 is inclined toward the front of the open-cabin vehicle 8, only one rotation suppressing member 6, i.e., one first L-shaped member 61, may be provided for the same support pillar 81. In this case, the second plate portion 612 of the first L-shaped member 61 contacts the second side surface 812 of the support pillar 81, suppressing clockwise rotation of the fastener 1, particularly at a portion below the second plate portion 612. The portion below the second plate portion 612 is shown, for example, by a dashed oval on the lower right side in FIG. 4. In addition, the inner surface of the second clamping member 22 fastened to the first clamping member 21 by the bolt 3 may contact the third side surface 813 of the support pillar 81, suppressing clockwise rotation of the fastener 1, particularly at an upper portion of the inner surface of the second clamping member 22.

[0028] 5, the second clamping member 22 has a crank shape with two consecutive L-shaped bent portions at its front, i.e., on the side of the third side surface 813 of the support column 81. In this case, the inner surface located between the consecutive L-shaped bent portions faces the third side surface 813 of the support column 81. When the first clamping member 21 and the second clamping member 22 included in the support member 2 are fastened with the bolt 3 to clamp the support column 81, the inner surface located between the bent portions of the second clamping member 22 may contact or abut against the third side surface 813 of the support column 81. Because the support column 81 is tilted forward, an upper portion of the third side surface 813 of the support column 81 comes into contact with an upper portion of the inner surface located between the bent portions of the second clamping member 22, and as a result, the clockwise rotation of the support member 2 including the second clamping member 22 is restricted by the third side surface 813 of the support column 81. In this way, by withstanding the clockwise stress applied to the support member 2 by the weight of the air conditioner 92 and the stand 9 at the two points indicated by the dashed ellipses in Figure 4, it is possible to restrict the rotation of the support member 2 around the horizontal axis that intersects with the first side surface 811 of the support column 81 at these two points.

[0029] (Embodiment 2) 8 is a perspective view showing the second L-shaped member 62 included in the rotation suppressing member 6 according to the second embodiment. The rotation suppressing member 6 further includes a second L-shaped member 62 in addition to the first L-shaped member 61 similar to that of the first embodiment. That is, the rotation suppressing member 6 includes the first L-shaped member 61 and the second L-shaped member 62. The second L-shaped member 62 is an L-shaped member having the same shape as the first L-shaped member 61 described in the first embodiment. That is, the first L-shaped member 61 and the second L-shaped member 62 may be the same part with the same part number or model.

[0030] The second L-shaped member 62 includes a third plate portion 623, a fourth plate portion 624, and a convex portion 63. The second L-shaped member 62 has the same shape as the first L-shaped member 61, and the third plate portion 623 of the second L-shaped member 62 corresponds to the second plate portion 612 of the first L-shaped member 61, and the fourth plate portion 624 of the second L-shaped member 62 corresponds to the first plate portion 611 of the first L-shaped member 61. A convex portion 63 is formed above the fourth plate portion 624 of the second L-shaped member 62, similar to the first plate portion 611 of the first L-shaped member 61.

[0031] FIG. 9 is a perspective view from the left rear, showing in perspective the state where the fixture 1 including the rotation inhibiting member 6 is clamping the support pillar 81. FIG. 10 is a perspective view from the right front, showing in perspective the state where the fixture 1 including the rotation inhibiting member 6 is clamping the support pillar 81. FIG. 11 is a side view from the left, showing in perspective the state where the fixture 1 including the rotation inhibiting member 6 is clamping the support pillar 81. FIG. 12 is a side view from the right, showing in perspective the state where the fixture 1 including the rotation inhibiting member 6 is clamping the support pillar 81. In this embodiment, the support pillar 81 of the open-cabin type vehicle 8 is inclined rearward.

[0032] The rotation suppression member 6 of the fixing device 1 includes a first L-shaped member 61 and a second L-shaped member 62, and the first L-shaped member 61 is disposed on the first side surface 811 and the second side surface 812 of the support pillar 81 as in the first embodiment, and the second L-shaped member 62 is disposed on the fourth side surface 814 and the third side surface 813 of the support pillar 81. Therefore, the first L-shaped member 61 and the second L-shaped member 62 are disposed opposite each other across the support pillar 81, and the corners of the first L-shaped member 61 and the second L-shaped member 62 are positioned along the diagonal of the support pillar 81, which has a rectangular shape in a cross-sectional view from above.

[0033] The support member 2 includes a first clamping member 21 and a second clamping member 22, similar to those in the first embodiment. The first clamping member 21 has a plurality of through holes 4 formed therein, similar to those in the first embodiment, and the second clamping member 22 also has a through hole 4 similar to that of the first clamping member 21. As in the first embodiment, a screw 7, for example, having a double point shape, is inserted into each of the through holes 4 of the first clamping member 21 and the second clamping member 22. The relationship in magnitude between the length of the shank of the screw 7 and the thickness of the second clamping member 22 and the second L-shaped member 62 is the same as that between the thickness of the first clamping member 21 and the first L-shaped member 61 in the first embodiment.

[0034] In terms of the positional relationship between the support pillar 81, the support member 2, and the rotation suppressing member 6, the first L-shaped member 61 is disposed relative to the support pillar 81 and the first clamping member 21 in the same manner as in the first embodiment. That is, the first plate portion 611 of the first L-shaped member 61 is clamped between the first side surface 811 of the support pillar 81 and the inner surface of the first clamping member 21, and the second plate portion 612 of the first L-shaped member 61 contacts the second side surface 812 of the support pillar 81. The protrusion 63 formed on the upper part of the first plate portion 611 of the first L-shaped member 61 contacts the upper surface of the first side surface 811 of the support pillar 81, preventing the first L-shaped member 61 from falling.

[0035] The fourth plate portion 624 of the second L-shaped member 62 is clamped between the fourth side surface 814 of the support 81 and the inner surface of the second clamping member 22. The third plate portion 623 of the second L-shaped member 62 contacts the third side surface 813 of the support 81. The protrusion 63 formed on the upper part of the fourth plate portion 624 of the second L-shaped member 62 contacts the upper surface of the fourth side surface 814 of the support 81, preventing the second L-shaped member 62 from falling.

[0036] As in the first embodiment, the first clamping member 21 and the second clamping member 22 included in the support member 2 are fastened with the bolts 3, so that the first L-shaped member 61, the support pillar 81, and the second L-shaped member 62 interposed between the first clamping member 21 and the second clamping member 22 are also clamped by the first clamping member 21 and the second clamping member 22. Therefore, the inner surface of the first clamping member 21, the first plate portion 611 of the first L-shaped member 61, the first side surface 811 of the support pillar 81, the fourth side surface 814 of the support pillar 81, the fourth plate portion 624 of the second L-shaped member 62, and the inner surface of the second clamping member 22 are arranged in this order from the left side to the right side of the open-cabin type vehicle 8, with adjacent surfaces facing each other.

[0037] In this way, two L-shaped members, consisting of a first L-shaped member 61 and a second L-shaped member 62, are arranged with respect to the support member 2 and the support pillar 81. As a result, rotation of the support member 2 about a horizontal axis intersecting with the first side surface 811 of the support pillar 81 can be suppressed by two locations: the first L-shaped member 61 and the second plate portion 612, which are contact portions with the second side surface 812 of the support pillar 81, and the second L-shaped member 62 and the third plate portion 623, which are contact portions with the third side surface 813 of the support pillar 81.

[0038] In the first L-shaped member 61, the portion below the second plate portion 612 particularly prevents the fastener 1 from rotating clockwise. The portion below the second plate portion 612 is shown, for example, by a dashed oval in FIG. 11. In the second L-shaped member 62, the portion above the third plate portion 623 particularly prevents the fastener 1 from rotating clockwise. The portion above the third plate portion 623 is shown, for example, by a dashed oval in FIG. 12.

[0039] In the support pillar 81, the second side surface 812 corresponding to the rear side surface and the third side surface 813 corresponding to the front side surface are surfaces parallel to a horizontal axis perpendicular to the first side surface 811 corresponding to the left side surface. By arranging the rotation suppressing members 6, i.e., the first L-shaped member 61 and the second L-shaped member 62, on the second side surface 812 and the third side surface 813, which are two of the sides of the support pillar 81 that are parallel to the horizontal axis, it is possible to firmly suppress the tilt of the frame 9, i.e., the rotation in the direction of gravity, even for an open-cabin type vehicle 8 in which the support pillar 81 is tilted backward.

[0040] In this embodiment, for example, a mount 9 for accommodating an air conditioner 92 and the like is attached to a support pillar 81 of an open-cabin vehicle such as a forklift using a fixing device 1. The mount 9 attached to the support pillar 81 using the fixing device 1 is configured to be rotatable about a vertical axis relative to the support pillar 81. The fixing device 1 includes a support member 2 and a rotation suppressing member 6. A first plate portion 611 of the rotation suppressing member 6 is disposed between a first side surface 811 of the support pillar 81 and an inner surface of the support member 2 facing the first side surface 811, and is sandwiched between the first side surface 811 of the support pillar 81 and the inner surface of the support member 2. Therefore, a layered structure is formed in the order of the first side surface 811 of the support pillar 81, the first plate portion 611 of the rotation suppressing member 6, and the inner surface of the support member 2. A second plate portion 612 of the rotation suppressing member 6 is connected to the first plate portion 611. Furthermore, the second plate portion 612 is in contact with a second side surface 812 adjacent to the first side surface 811 of the support column 81, and this contact can suppress rotation of the support member 2 relative to the support column 81 about the horizontal axis. That is, the second plate portion 612 of the rotation suppressing member 6 functions as a rotation stopper. When the base 9 is rotated and moved relative to the support column 81 with an air conditioner 92 and other items stored in it, a force corresponding to the longitudinal length of the base 9 is applied to the support member 2 in response to the weight of the air conditioner 92 and the base 9, due to the principle of leverage, and stress is applied to the support member 2 in the clockwise direction as viewed from the left. In response to this, the second plate portion 612 of the rotation suppressing member 6 fixed to the support member 2 comes into contact with the second side surface 812 of the support column 81, thereby restricting rotation of the support member 2 due to the clockwise stress. Therefore, tilting of the frame 9, that is, rotation in the direction of gravity, can be suppressed without directly fixing the frame 9 to the support pillar 81 of the open cabin type vehicle 8 by, for example, screwing or welding.

[0041] In this embodiment, the rotation suppressing member 6 further includes a third plate portion 623 that contacts the third side surface 813. As a result, the rotation suppressing member 6 is disposed on two of the side surfaces of the support 81 that are parallel to the horizontal axis, so that tilting of the pedestal 9, i.e., rotation in the direction of gravity, can be more firmly suppressed.

[0042] In this embodiment, the support 81 has a rectangular shape in a cross-sectional view and has a first side surface 811, a second side surface 812, a third side surface 813, and a fourth side surface 814. In this case, the first side surface 811 corresponds to the left side surface, the second side surface 812 corresponds to the rear side surface, the third side surface 813 corresponds to the front side surface, and the fourth side surface 814 corresponds to the right side surface, and the first side surface 811 and the fourth side surface 814 face each other, and the second side surface 812 and the third side surface 813 face each other. In this case, the second side surface 812 and the third side surface 813 correspond to the side surfaces of the support 81 that are parallel to the horizontal axis. The first side surface 811 and the fourth side surface 814 correspond to the side surfaces of the support 81 that are perpendicular to the horizontal axis. The second plate portion 612 and the third plate portion 623 of the rotation suppressing member 6 function as rotation suppressing portions, and each rotation suppressing portion can suppress rotation of the support member 2 relative to the support column 81 at two contact points, the second side surface 812 and the third side surface 813, thereby more firmly suppressing tilt of the pedestal 9, i.e., rotation in the direction of gravity. For example, if the support column 81 is tilted backward, when stress is applied to the support member 2 in the clockwise direction as viewed from the left, it is expected that the inner surface of the support member 2 will not come into contact with the fourth side surface 814 in a manner that restricts rotation of the support member 2. Even in such a case, because the second side surface 812 of the other rotation suppressing member 6 contacts the fourth side surface 814, even when the support column 81 of the open-cabin vehicle 8 is tilted backward, it can withstand stress in the clockwise direction due to the weight of the air conditioner 92 and the pedestal 9, and can suppress tilt of the pedestal 9, i.e., rotation in the direction of gravity.

[0043] In this embodiment, the rotation suppressing member 6 has a first L-shaped member 61 and a second L-shaped member 62. The first L-shaped member 61 includes the first plate portion 611 and the second plate portion 612, which are integrally formed. The second L-shaped member 62 includes the third plate portion 623 and the fourth plate portion 624, which are integrally formed. In this manner, in the first L-shaped member 61 and the second L-shaped member 62, the portion that is clamped by the inner surface of the support member 2 and the portion that contacts the strut 81 and functions as a rotation preventing portion are integrally formed, thereby reducing the number of parts and simplifying the installation work.

[0044] In this embodiment, the rotation suppressing member 6 includes a first L-shaped member 61 and a second L-shaped member 62, and these first L-shaped member 61 and second L-shaped member 62 have the same shape. By arranging the first L-shaped member 61 and the second L-shaped member 62 in opposing positions across a single support 81, these first L-shaped member 61 and second L-shaped member 62 can be made into the same part with the same shape, i.e., the same part number or model. Therefore, when attaching the rotation suppressing member 6 to the support 81, it is possible to reliably prevent the first L-shaped member 61 and the second L-shaped member 62 from being attached incorrectly, such as being attached upside down. For example, if the two rotation suppressing members 6 attached to the first side surface 811 and the fourth side surface 814 of the support 81 have different shapes, there is a concern that the rotation suppressing member 6 that should be attached to the fourth side surface 814 may be attached to the first side surface 811 instead. In contrast, by making the first L-shaped member 61 and the second L-shaped member 62 included in the rotation suppressing member 6 the same shape, polarity during installation is eliminated, making it possible to reliably prevent incorrect installation. Furthermore, by making the first L-shaped member 61 and the second L-shaped member 62 included in the rotation suppressing member 6 the same part, parts can be standardized, thereby reducing part costs.

[0045] In this embodiment, the rotation suppressing member 6 has a protrusion 63 that contacts the upper surface of the support member 2. This protrusion 63 contacts and engages with the upper surface of the support member 2, thereby preventing the rotation suppressing member 6 from falling downward when the rotation suppressing member 6 is attached. For example, after the rotation suppressing member 6 is disposed between the inner surface of the support member 2 and the first side surface 811 of the support 81, it is expected that the rotation suppressing member 6 will fall downward when the rotation suppressing member 6 is fixed to the support member 2. Even in such a case, the protrusion 63 of the rotation suppressing member 6 contacts the upper surface of the support member 2, so the rotation suppressing member 6 can be temporarily fixed to the support member 2, effectively preventing the rotation suppressing member 6 from falling downward.

[0046] In this embodiment, the convex portion 63 of the rotation suppressing member 6 is formed by bending it relative to the first plate portion 611. That is, the rotation suppressing member 6 has the convex portion 63 formed by bending it relative to the first plate portion 611, and the second plate portion 612 formed by bending it relative to the first plate portion 611. In this case, the side of the first plate portion 611 on which the convex portion 63 is formed is adjacent to the side of the first plate portion 611 on which the second plate portion 612 is formed. The bending direction of the convex portion 63 relative to the first plate portion 611 is opposite to the bending direction of the second plate portion 612 relative to the first plate portion 611. Because the convex portion 63 is formed by bending the rectangular first plate portion 611 in this way, the rotation suppressing member 6 having the convex portion 63 can be manufactured with a relatively simple configuration.

[0047] In this embodiment, a through hole 4 is formed in the support member 2, and an internal thread may be formed on the inner peripheral surface of the through hole 4. A screw 7 is inserted into the through hole 4, which functions as the internal thread, from the outer surface side of the support member 2. The length of the shank of the screw 7, on which the spiral groove is formed, is greater than the thickness of the support member 2 and less than the combined thickness of the support member 2 and the rotation suppressing member 6. The tip of the inserted screw 7 presses against the first plate portion 611 of the rotation suppressing member 6, thereby fixing the rotation suppressing member 6 to the support member 2, and therefore the rotation suppressing member 6 can be fixed to the support member 2 with a relatively simple configuration.

[0048] In this embodiment, the through holes 4 formed in the support member 2 include at least two through holes 4: an upper through hole 4 formed above the support column 81 in the height direction, and a lower through hole 4 formed below the support column 81 in the height direction. Since the support member 2 and the rotation suppressing member 6 are fixed at two locations, the upper through hole 4 and the lower through hole 4, the clockwise stress applied to the support member 2 by the weight of the air conditioner 92 and the pedestal 9 can be distributed to these two locations, and tilting of the pedestal 9, i.e., rotation in the direction of gravity, can be effectively suppressed.

[0049] In this embodiment, the support member 2 has a plurality of through holes 4, for example, three, formed at equal intervals along the width direction of the first side surface 811 of the support pillar 81, which is in the fore-and-aft direction of the open-cabin type vehicle 8. The through holes 4 include two through holes 4, one on the upper side and one on the lower side, and these two through holes 4 on the upper side and the other on the lower side form a pair and are formed in plurality along the width direction of the support pillar 81. When attaching the fastener 1 to the support pillar 81 of the open-cabin type vehicle 8, it is expected that the shape of the support pillar 81, such as its width and inclination, will differ depending on the vehicle model of the open-cabin type vehicle 8. Even in such a case, since the support member 2 has a plurality of through holes 4 formed along the width direction of the support pillar 81, by applying one of the through holes 4 according to each support whose shape differs depending on the vehicle model of the open-cabin type vehicle 8, it is possible to accommodate a plurality of vehicle models, thereby improving the availability and versatility of the fastener 1.

[0050] In this embodiment, the tip of the screw 7 has a double-point shape, and the double-pointed tip bites into the first plate portion 611 of the rotation-restricting member 6, thereby fixing the rotation-restricting member 6 to the support member 2. This increases the frictional force between the tip of the screw 7 and the first plate portion 611, making it possible to effectively restrict tilting of the pedestal 9, i.e., rotation in the direction of gravity.
