Summary of the Invention

Problems to be Solved by the Invention

[0004] On the side of the vehicle, a door is arranged. When the vehicle is impacted, an airbag deployed downward from the ceiling on the side of the vehicle can protect the occupant's head from the broken glass of the door. If gas is supplied to the airbag arranged on the ceiling of the vehicle, the airbag is likely to deploy downward due to gravity. Therefore, the airbag may be arranged near the side end of the ceiling of the vehicle. In the vicinity of the side end of the ceiling of the vehicle, there may not be enough space for attaching instruments in the vertical direction. In the airbag device of Patent Document 1, a bracket extends downward from the ceiling side of the vehicle. Further, an airbag is fixed below the bracket. Therefore, in Patent Document 1, the area occupied by the airbag device in the vertical direction of the vehicle is large. Thus, depending on the shape of the side of the vehicle, there is a possibility that the airbag device of Patent Document 1 cannot be accommodated.

Means for Solving the Problems

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to one aspect of the present disclosure, an attachment device is provided. This attachment device is an attachment device for attaching an airbag that deploys downward from the ceiling of a moving body along the inner side wall of the moving body to the moving body, and includes a first plate member fixed to the interior of the moving body and a second plate member to which a tab of the airbag is fixed. The first plate member and the second plate member are arranged in different directions, and the attachment device includes an attachment hole through which the tab of the airbag passes, a part of the attachment hole being in the first plate member and another part of the attachment hole being in the second plate member. According to the attachment device of this aspect, compared with the aspect in which the first plate member and the second plate member are arranged so as to form the same plane, the dimension in the direction along the first plate member can be reduced. For this reason, it can be attached together with the airbag to the space near the side end of the ceiling of the moving body. (2) In the mounting device of the above-described embodiment, the first plate portion includes a fixing portion for being fixed to the moving body, a part of one end of the second plate portion is connected to the first plate portion, and the other part of the mounting hole is located closer to the one end side than an intermediate portion along a direction from the one end to the other end of the second plate portion. The second plate portion may be configured such that the tab is arranged from the mounting hole to the other end. Generally, when an impact is applied to a moving body, an airbag inflates by being supplied with gas. In a mode where the airbag deploys downward from the ceiling of the moving body, as the airbag inflates in a direction from the ceiling of the moving body downward, a force is applied to the mounting device from the airbag in a direction from the ceiling of the moving body downward. When the mounting device is fixed to the ceiling of the moving body, there is a risk that the mounting device is pulled downward and deformed with the fixed portion as a fulcrum. According to the mounting device of this embodiment, for example, compared with a mode where the mounting hole is located closer to the other end side than the intermediate portion of the second plate portion, the linear distance between the fixing portion and any point where the tab contacts in the mounting hole can be reduced. That is, when the center of the fixing portion is used as a fulcrum, the linear distance to the force point can be reduced. Compared with a mode where a portion closer to the other end of the second plate portion becomes the force point, when a force is applied to the mounting device, the mounting device can suppress deformation. (3) In the mounting device of the above-described embodiment, the mounting hole may include a first position that is an intermediate position in the longitudinal direction of the first plate portion and a second position that is an intermediate position in the longitudinal direction of the second plate portion. Generally, when an impact is applied to a moving body, an airbag inflates by being supplied with gas. In a mode where the airbag deploys downward from the ceiling of the moving body, as the airbag inflates in a direction from the ceiling of the moving body downward, a force is applied to the mounting device from the airbag in a direction from the ceiling of the moving body downward. When the mounting device is fixed to the ceiling of the moving body, there is a risk that the mounting device is pulled downward and deformed with the fixed portion as a fulcrum. According to the mounting device of this form, compared with the mode in which the mounting hole does not include the first position and the second position that are in the middle in the longitudinal direction of the first plate portion and the second plate portion, force is evenly applied to the second plate portion. When force is applied to the mounting device, the possibility of the second plate portion being distorted can be reduced. (4) In the mounting device of the above form, the fixing portion is a through hole for passing a component, and the first plate portion may be fixed to the moving body via the component passed through the through hole. According to the mounting device of this form, for example, compared with the mode in which the first plate portion is fixed to the moving body by an adhesive, the mounting device can be easily replaced.

Embodiments for Carrying Out the Invention

[0008] A. This Embodiment: A1. Configuration of this Embodiment: FIG. 1 is an explanatory diagram showing an airbag device 1 disposed in a vehicle VW. FIG. 1 is a diagram that simplifies a partial cross-section of the interior of the vehicle VW. In FIG. 1, hatching is omitted. In FIG. 1, the forward direction FD indicates the front in the traveling direction of the vehicle VW, and the rear direction BD indicates the rear in the traveling direction of the vehicle VW. The upward direction UD indicates the upper side in the height direction of the vehicle VW, and the downward direction DD indicates the lower side in the height direction of the vehicle VW. The direction perpendicular to the forward direction FD, the rear direction BD, the upward direction UD, and the downward direction DD is denoted as the left-right direction. The right direction RD is the direction toward the interior of the vehicle VW. The left direction LD is the direction toward the outside of the vehicle VW. The forward direction FD and the rear direction BD may also be collectively referred to as the front-rear direction, the upward direction UD and the downward direction DD may be collectively referred to as the up-down direction, and the left direction LD and the right direction RD may be collectively referred to as the left-right direction.

[0009] FIG. 1 shows a part of a vehicle panel CP, a deformation member DM, and an airbag device 1, which will be described later, on the left direction LD side of the vehicle VW. On the right direction RD side of the vehicle VW, the part of the vehicle panel CP, the deformation member DM, and the airbag device 1 in FIG. 1 have a symmetrical configuration in a plane including the up-down direction and the front-rear direction. Hereinafter, a part of the vehicle panel CP, the deformation member DM, and the airbag device 1 on the left direction LD side of the vehicle VW will be described.

[0010] Vehicle VW includes a vehicle panel CP and a deformation member DM. The vehicle panel CP is a part of the ceiling of vehicle VW. The vehicle panel CP is a plate-shaped member. In this embodiment, the vehicle panel CP includes twelve vehicle body holes BH and four fitting portions FP. The vehicle body holes BH are holes for fixing the mounting device 10 (to be described later) of the airbag device 1 to the vehicle panel CP by passing through the components passing through the first through hole 112a to the third through hole 112c (to be described later). In this embodiment, three vehicle body holes BH are used to fix one mounting device 10. In FIG. 1, only one vehicle body hole BH is shown. In this embodiment, the component is a bolt BT. The fitting portion FP is a portion that fits into the hole of the opening portion DM2 (to be described later). The fitting portion FP is formed at the lower end portion DD of the vehicle panel CP. The portion of the vehicle panel CP other than the fitting portion FP extends along the front-rear direction of the vehicle VW. Although not shown, the side wall of the vehicle VW is arranged in the lower direction DD of the vehicle panel CP.

[0011] The deformation member DM is a member that deforms when the airbag 20 (to be described later) of the airbag device 1 deploys. The deformation member DM includes a ceiling portion DM1 and four opening portions DM2. The ceiling portion DM1 is a member that is pushed downward DD of the vehicle VW by the airbag 20 when the airbag 20 deploys. The ceiling portion DM1 is a part of the ceiling of the vehicle VW. The ceiling portion DM1 is a plate-shaped member. The ceiling portion DM1 extends from the upper direction UD to the lower direction DD of the vehicle VW and further extends toward the side wall of the vehicle VW. Also, the ceiling portion DM1 extends along the front-rear direction of the vehicle VW. The ceiling portion DM1 is arranged downward DD with respect to the vehicle panel CP. The airbag 20 is accommodated in the space between the vehicle panel CP and the ceiling portion DM1. The ceiling portion DM1 is formed of a material that can be elastically deformed. The ceiling portion DM1 pushed downward DD elastically deforms downward DD.

[0012] The opening part DM2 is a member that engages with the vehicle panel CP when the airbag 20 is not deployed. Specifically, the opening part DM2 engages with the vehicle panel CP by having a hole DM21 into which the fitting part FP of the vehicle panel CP fits. The opening part DM2 is connected to the lower end of the ceiling part DM1. When the airbag 20 is deployed, the opening part DM2 is pulled by the ceiling part DM1 that is pushed downward in the downward direction DD. When the opening part DM2 is pulled by the ceiling part DM1, the fitting part FP is configured to come out of the hole DM21. In this way, the engagement between the opening part DM2 and the vehicle panel CP is released. Although not shown in the figure, when the engagement between the opening part DM2 and the vehicle panel CP is released, a gap is generated between the opening part DM2 and the vehicle panel CP. The deployment of the airbag 20 will be described later. In the present embodiment, four opening parts DM2 are arranged along the front-rear direction of the vehicle VW. Specifically, each of the four opening parts DM2 is arranged downward in the downward direction DD of one of the four mounting devices 10 described later. One opening part DM2 is interlocked with the airbag 20 fixed to one mounting device 10.

[0013] Figure 2 is a view showing a part of the airbag device 1. In Figure 2, a part of the airbag device 1 is illustrated. The airbag device 1 is mounted on the vehicle VW, which is a moving body. The airbag device 1 protects the occupants in the vehicle VW by deploying when the vehicle VW collides or when a collision is predicted by an ECU of a vehicle (not shown). The airbag device 1 in the present embodiment is also called a curtain airbag. The airbag device 1 is fixed to the vehicle panel CP. In the present embodiment, the vehicle VW is provided with one airbag device 1 at each of the left and right ends. Hereinafter, the airbag device 1 on the left direction LD side of the vehicle VW will be described. The airbag device 1 includes four mounting devices 10 and an airbag 20. In Figure 2, one mounting device 10 and a tab 220, which will be described later with respect to the airbag 20, are shown.

[0014] In FIG. 2, the forward direction FD, the rearward direction BD, the upward direction UD, the downward direction DD, the leftward direction LD, and the rightward direction RD are illustrated in a state where the airbag device 1 is mounted on the vehicle VW. Further, in FIG. 2, the first direction 1D, the second direction 2D, and the third direction 3D are represented. The first direction 1D is a direction along the long sides of the first plate portion 110 and the second plate portion 120, which will be described later. The second direction 2D is a direction perpendicular to the first direction 1D and along the short side of the first plate portion 110. The third direction 3D is a direction perpendicular to the first direction 1D and the second direction 2D and along the short side of the second plate portion 120. In the present embodiment, the first direction 1D is parallel to the front-rear direction, the second direction 2D is parallel to the up-down direction, and the third direction 3D is parallel to the left-right direction. The forward direction FD corresponds to the positive direction of the first direction 1D, the upward direction UD corresponds to the positive direction of the second direction 2D, and the rightward direction RD corresponds to the positive direction of the third direction 3D.

[0015] FIG. 3 is a view showing the mounting device 10 when viewed from an angle different from that of FIG. 2. In FIG. 3, the airbag 20 is omitted. FIG. 4 is a view showing the mounting device 10 when viewed from an angle different from that of FIG. 3. The mounting device 10 is a device for attaching the airbag 20 to the vehicle VW. Although not shown, in the present embodiment, four mounting devices 10 are arranged along the front-rear direction. By fixing one airbag 20 to each of the four mounting devices 10, the airbag 20 is arranged along the front-rear direction of the vehicle VW. The four mounting devices 10 have the same configuration. Hereinafter, one mounting device 10 will be described.

[0016] As shown in FIG. 1, the mounting device 10 is fixed to the vehicle panel CP of the vehicle VW. In the present embodiment, the mounting device 10 is formed by pressing a metal plate. As shown in FIG. 3, the mounting device 10 includes a first plate portion 110, a second plate portion 120, and a bent portion 130. The first plate portion 110 is a plate-shaped member fixed to the interior of the vehicle VW. The first plate portion 110 is configured such that its long side extends along the first direction 1D and its short side extends along the second direction 2D. As shown in FIG. 4, the intermediate position of the first plate portion 110 in the first direction 1D, which is the longitudinal direction, is denoted as the first position 111. In the present embodiment, the first plate portion 110 is fixed to the vehicle panel CP of the vehicle VW. As shown in FIG. 3, the first plate portion 110 includes a fixing portion 112 and a locking portion 113.

[0017] The fixing portion 112 is a portion for fixing to the vehicle VW. In the present embodiment, the fixing portion 112 is a portion fixed to the vehicle panel CP. In the present embodiment, the fixing portion 112 is three through-holes for passing bolts BT which are components. The three through-holes are denoted as a first through-hole 112a, a second through-hole 112b, and a third through-hole 112c, respectively. Although not shown, the bolts BT are passed through in a state where each of the three body holes BH of the vehicle panel CP described above, the first through-hole 112a, the second through-hole 112b, and the third through-hole 112c are overlapped in the third direction. The first plate portion 110 is fixed to the vehicle panel CP via the bolts BT passed through the first through-hole 112a, the second through-hole 112b, and the third through-hole 112c. For example, compared with a mode in which the first plate portion 110 is fixed to the vehicle VW by an adhesive, the mounting device 10 can be easily replaced. The first through-hole 112a is formed at an intermediate position in the longitudinal direction of the first plate portion 110. Each of the second through-hole 112b and the third through-hole 112c is formed at an end in the longitudinal direction of the first plate portion 110, respectively.

[0018] The engaging portion 113 is a portion that is engaged with an engaged portion (not shown) of the vehicle panel CP. With the engaging portion 113 engaged with the engaged portion, bolts BT are passed through the first through-hole 112a to the third through-hole 112c. The engaging portion 113 is a portion that protrudes toward the negative side in the third direction 3D. The engaging portion 113 is formed around the end portion on the positive side in the second direction 2D of the first plate portion 110. When the engaging portion 113 is engaged, the vehicle body hole BH and the first through-hole 112a to the third through-hole 112c overlap in the third direction. Therefore, the engaging portion 113 functions as a positioning means when the mounting device 10 is fixed to the vehicle VW.

[0019] FIG. 5 is a view showing the mounting device 10 when viewed from an angle different from that in FIG. 3. The second plate portion 120 is a plate-shaped member to which a tab 220 (to be described later) of the airbag 20 is fixed. As shown in FIG. 3, one end portion 121 of the second plate portion 120 is connected to the bent portion 130. A part of one end portion 121 of the second plate portion 120 is connected to the first plate portion 110 via the bent portion 130. The long side of the second plate portion 120 extends along the first direction 1D, and the short side extends along the third direction 3D. As described above, since the short side of the first plate portion 110 extends along the second direction 2D, the second plate portion 120 is arranged in a direction different from that of the first plate portion 110. In the present embodiment, the first plate portion 110 is arranged along the vertical direction of the vehicle VW, while the second plate portion 120 is arranged along the left-right direction of the vehicle VW. Compared with the aspect in which the first plate portion 110 and the second plate portion 120 are arranged to form the same plane, the dimension in the direction along the first plate portion 110 can be reduced. For this reason, it can be mounted together with the airbag 20 in the space near the side end portion of the ceiling of the vehicle VW. As shown in FIG. 5, the intermediate position of the second plate portion 120 in the first direction 1D, which is the longitudinal direction, is denoted as the second position 122.

[0020] The bent portion 130 shown in FIG. 3 is a portion connecting the first plate portion 110 and the second plate portion 120. In FIG. 3, for ease of understanding, the bent portion 130 is hatched. The bent portion 130 includes a first bent portion 131 and a second bent portion 132. The first bent portion 131 connects to a part of the end of the long side of the first plate portion 110 and a part of the end of the long side of the second plate portion 120. The first bent portion 131 is bent when viewed along the first direction 1D. The second bent portion 132 connects to a part of the other part of the end of the long side of the first plate portion 110 and a part of the other part of the end of the long side of the second plate portion 120. The second bent portion 132 is bent when viewed along the first direction 1D. The second bent portion 132 is spaced apart from the first bent portion 131 in the first direction 1D.

[0021] As shown in FIG. 3, the mounting device 10 includes a mounting hole 140. The mounting hole 140 is a hole through which the tab 220 of the airbag 20 passes. The mounting hole 140 is formed by the connection of the first plate portion 110, the second plate portion 120, and the bent portion 130. The shape of the mounting hole 140 is defined by a part of the long side of the first plate portion 110, a part of the long side of the second plate portion 120, and the bent portion 130. In the present embodiment, the shape of the mounting hole 140 is defined by the part of the ends of the long sides of the first plate portion 110 and the second plate portion 120 that are not connected to the bent portion 130 and the end of the short side of the bent portion 130. A part of the mounting hole 140 is in the first plate portion 110. Another part of the mounting hole 140 is in the second plate portion 120. As shown in FIG. 5, in the present embodiment, another part of the mounting hole 140 is on the side of one end 121 rather than the intermediate part 124, which is an intermediate site along the third direction 3D from one end 121 to the other end 123 of the second plate portion 120. In the present embodiment, the mounting hole 140 includes the first position 111 of the first plate portion 110 (see FIG. 4). Also, in the present embodiment, the mounting hole 140 includes the second position 122 of the second plate portion 120 (see FIG. 5). The mounting hole 140 has a shape extending in the first direction 1D.

[0022] The airbag 20 shown in FIG. 1 is a device that protects the occupants by deploying when the vehicle VW is impacted or when it is predicted that the vehicle VW will be impacted. The airbag 20 deploys downward from the ceiling of the vehicle VW along the side wall inside the vehicle VW. In the present embodiment, the airbag 20 deploys downward DD from the vehicle panel CP that constitutes the ceiling of the vehicle VW along the side wall inside the vehicle VW. The airbag 20 includes an airbag body 210 and four tabs 220. The airbag body 210 inflates when gas is supplied when the vehicle VW is impacted or when it is predicted that the vehicle VW will be impacted. The airbag body 210 is folded as shown in FIG. 1 when no gas is supplied. When gas is supplied to the airbag body 210, the inflated airbag body 210 pushes the ceiling portion DM1 downward DD. When the engagement between the opening portion DM2 connected to the ceiling portion DM1 and the vehicle panel CP is released by the opening portion DM2 being pulled by the ceiling portion DM1, the airbag body 210 deploys downward DD. As described above, in the present embodiment, one airbag body 210 is attached to four mounting devices 10 via four tabs 220. When the airbag body 210 deploys, the engagement between the four opening portions DM2 of the deformation member DM and the vehicle panel CP is released. As a result, the airbag body 210 is fully deployed. The airbag body 210 is formed by sewing a plurality of fabrics. The airbag 20 has a bag shape.

[0023] FIG. 6 is a schematic view showing the state where the airbag 20 is attached to the attachment device 10. The shapes of the vehicle panel CP and the airbag device 1 shown in FIG. 6 are simplified for explanation. The tab 220 is a part for attaching the airbag body 210 to the attachment device 10. One tab 220 is attached to one attachment device 10. The four tabs 220 have the same configuration. Hereinafter, one tab 220 will be described. As shown in FIG. 2, the tab 220 is fixed to the mounting hole 140 by being passed through the mounting hole 140. In the present embodiment, the tab 220 is formed of cloth. The tab 220 is fixed to the mounting hole 140 by sewing the ends of the tab 220 passed through the mounting hole 140 together. Although not shown in FIG. 2, the airbag body 210 is sewn to the end of the tab 220. The tab 220 is configured to be arranged from the mounting hole 140 across the other end 123 of the second plate portion 120.

[0024] A2. Comparison between the comparative example and the present embodiment: FIG. 7 is a view showing the airbag device 50 of the comparative example. FIG. 8 is a view showing the airbag 510 of the airbag device 50 of the comparative example being deployed. The structure of the attachment device 520 of the airbag device 50 of the comparative example is different from the structure of the attachment device 10 of the present embodiment. In the comparative example, the mounting hole 530 is only in the second plate portion 540. Also, in the comparative example, the mounting hole 530 includes a portion on the other end side of the second plate portion 540 rather than the middle portion.

[0025] Generally, when an impact is applied to the vehicle VW, the airbag 20 inflates by the supply of gas. In the mode where the airbag 20 deploys downward from the ceiling of the vehicle VW, as the airbag 20 inflates in the direction from the ceiling of the vehicle VW downward, a force is applied to the mounting device 10 from the airbag 20 in the direction from the ceiling of the vehicle VW downward. When the mounting device 10 is fixed to the ceiling of the vehicle VW, there is a risk that the mounting device 10 is pulled downward and deformed with the fixed part as a fulcrum (see FIG. 8). In the comparative example, the distance between the center of the first through-hole 550 of the mounting device 10 and a comparison point PC, which is an arbitrary point where the tab 560 of the airbag 510 contacts the mounting hole 530 among the mounting holes 530, is DH1 (see FIG. 7). As described above, in the mounting device 10 of the present embodiment, a part of the other mounting hole 140 is on the end 121 side rather than the intermediate part 124 of the second plate part 120 (see FIG. 5). The distance between the center of the first through-hole 112a of the mounting device 10 and an arbitrary point AP, which is an arbitrary point where the tab 220 of the airbag 20 contacts the mounting hole 140 among the mounting holes 140, is DH2 (see FIG. 6). The distance DH2 is smaller than the distance DH1. Note that the comparison point PC shown in FIG. 7 is an intermediate part at the end of the long side of the 540 of the second plate part of the comparative example. The arbitrary point AP shown in FIG. 6 is the second position 122, which is an intermediate position at the end of the long side of the second plate part 120.

[0026] In the mounting device 10 of the present embodiment, compared with the aspect where the mounting hole 140 is on the other end 123 side of the second plate portion 120 rather than in the middle part, the first through hole 112a which is the fixing portion 112 and the straight-line distance between any point on the mounting hole 140 where the tag contacts can be reduced (refer to the distance DH1 in FIG. 7 and the distance DH2 in FIG. 6). In addition, also in the second through hole 112b and the third through hole 112c, the straight-line distance between any point on the mounting hole 140 where the tag contacts can be reduced compared with the comparative example. That is, when the center of the fixing portion 112 is used as a fulcrum, the straight-line distance from the effort point can be reduced. Compared with the aspect where the portion of the second plate portion 120 close to the other end 123 becomes the effort point, when a downward force DD is applied to the mounting device 10 by the airbag 20, the magnitude of the force required for the second plate portion 120 to deform downward DD increases. Compared with the aspect where the portion of the second plate portion 120 close to the other end 123 becomes the effort point, the mounting device 10 can suppress deformation.

[0027] Also, in the present embodiment, compared with the aspect where the mounting hole 140 does not include the first position 111 and the second position 122 which are in the middle in the longitudinal direction of the first plate portion 110 and the second plate portion 120, when the airbag 20 deploys, force is evenly applied from the airbag 20 to the second plate portion 120. When force is applied to the mounting device 10, the possibility that the second plate portion 120 is distorted can be reduced.

[0028] B. Other Embodiments: B1. Other Embodiment 1: (1) In the above embodiment, the mounting device 10 includes a bent portion 130. Note that, for example, the mounting device may not include a bent portion, and the first plate portion and the second plate portion may be directly connected.

[0029] (2) In the above embodiment, the mounting device 10 is mounted on the vehicle VW. Note that the airbag device may be mounted on a moving body other than a vehicle. For example, the airbag device may be mounted on a moving body such as an airplane or a ship.

[0030] (3) In the above-described embodiment, the front-rear direction is parallel to the first direction 1D, the up-down direction is parallel to the second direction 2D, and the left-right direction is parallel to the third direction 3D. Note that, for example, the front-rear direction may not be completely parallel to the first direction, the up-down direction may not be completely parallel to the second direction, and the left-right direction may not be completely parallel to the third direction.

[0031] (4) In the above-described embodiment, the tab 220 is formed of cloth. For example, the tab may be formed of metal. In this form, for example, holes for passing bolts are formed in the tab, and the airbag body and the tab may be connected via bolts.

[0032] (5) In the above-described embodiment, an airbag device 1 is provided on each of the left and right sides of the vehicle VW. For example, one airbag device may be provided on one of the left and right sides of the vehicle.

[0033] (6) In the above-described embodiment, four mounting devices 10 are mounted on the vehicle VW in the left-right direction, and one tab 220 is attached to each of the four mounting devices 10. For example, one mounting device may be mounted in the left-right direction of the vehicle. In this aspect, in each of the left and right directions, the deformable member may include one opening.

[0034] B2. Other Embodiment 2: (1) In the above-described embodiment, the first plate portion 110 includes a fixing portion 112 for fixing to the moving body. For example, in the aspect where the first plate portion is fixed to the moving body by an adhesive, the first plate portion may not include a fixing portion.

[0035] (2) In the above-described embodiment, another part of the mounting hole 140 is on one end portion 121 side of the second plate portion 120 rather than the intermediate portion 124. Note that, for example, another part of the mounting hole may be on the other end portion side of the second plate portion rather than the intermediate portion.

[0036] B3. Other Embodiment 3: (1) In the above embodiment, the mounting hole 140 includes a first position 111 and a second position 122. For example, the mounting hole may not include the first position and the second position. For example, the mounting hole may be in a mode that includes the first position and does not include the second position. Also, for example, the mounting hole may be in a mode that includes the second position and does not include the first position. Even in this mode, compared with the mode where the mounting hole does not include the second position, force is evenly applied to the second plate portion. When force is applied to the mounting device, the possibility of the second plate portion being distorted can be reduced.

[0037] (2) In the above embodiment, the mounting hole 140 has a shape extending in the first direction 1D. For example, the mounting hole may have a substantially circular shape.

[0038] B4. Other Embodiment 4: (1) In the above embodiment, the first plate portion 110 is provided with a first through hole 112a to a third through hole 112c. By fixing the first plate portion to the vehicle panel through the three through holes, the mounting device is more firmly fixed to the vehicle panel compared with, for example, a mode where the first plate portion is provided with one through hole. Note that, for example, the fixing portion may include only the first through hole. Even in this form, the mounting device can be easily replaced compared with a mode where the fixing portion is fixed to the moving body by an adhesive.

[0039] (2) In the above embodiment, the first through hole 112a to the third through hole 112c are holes for passing bolts BT which are parts. For example, the through hole may be a hole for a convex portion formed on the vehicle to fit in.

[0040] (3) For example, the fixing portion may be a convex portion formed on the first plate portion. The mounting device may be fixed to the vehicle by the convex portion fitting into a hole formed in the vehicle. Even in this form, the mounting device can be easily replaced compared with a mode where the fixing portion is fixed to the moving body by an adhesive.

[0041] The present disclosure is not limited to the above-described embodiments and can be implemented in various configurations without departing from the gist thereof. For example, the technical features of the embodiments corresponding to the technical features in each form described in the summary of the invention can be appropriately replaced or combined in order to solve some or all of the above-described problems or to achieve some or all of the above-described effects. Further, if the technical feature is not described as essential in this specification, it can be appropriately deleted.
