[0003] [Patent Document 1] JP 2020-131809 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in conventional camera mounting structures, since the latched parts are located on the left, right, and front of the camera, it is not easy to remove the camera from the bracket when inspecting, replacing, etc. Similarly, it is not easy to remove the camera (imaging device) and then attach it to the bracket.

[0009] Hereinafter, an embodiment to which the bracket device of the present disclosure is applied will be described. In the following, the same elements will be given the same reference numerals, and duplicated explanations may be omitted.

[0010] In the following, the XYZ coordinate system is defined and described. The direction parallel to the X axis (X axis direction), the direction parallel to the Y axis (Y axis direction), and the direction parallel to the Z axis (Z axis direction) are mutually orthogonal. The XY plane, the YZ plane, and the ZX plane respectively represent virtual planes parallel to the X axis direction and the Y axis direction, virtual planes parallel to the Y axis direction and the Z axis direction, and virtual planes parallel to the Z axis direction and the X axis direction. Moreover, a plan view refers to an XY plane view. Moreover, in the following, the length, width, thickness, and the like of each part may be exaggerated to make the configuration easier to understand. Moreover, the terms parallel, right angle, orthogonal, horizontal, vertical, up and down, and the like are allowed to be misaligned to a degree that does not impair the effect of the embodiment.

[0011] Examples of the window glass of the vehicle to which the bracket device of the embodiment is attached include a windshield (front glass) attached to the front of the vehicle, a side glass attached to the side of the vehicle, a roof glass attached to the ceiling of the vehicle, a rear glass attached to the rear of the vehicle, etc. The window glass of the vehicle to which the bracket device is attached is not limited to these examples, and may be slidable relative to the vehicle body. In the following, as an example, a form in which the window glass of the vehicle to which the bracket device of the embodiment is attached is a windshield (front glass) will be described.

[0012] <Embodiment> Fig. 1 is a diagram showing an example of a state in which a bracket device 100 of an embodiment is attached to a window glass 10 of a vehicle. Fig. 1 shows the bracket device 100 attached to the window glass 10 from the inside of the vehicle. In this example, the window glass 10 is a windshield, and therefore the window glass 10 is laminated glass. However, when the window glass 10 is something other than a windshield, the window glass 10 may be a single sheet of glass.

[0013] The bracket device 100 is attached to the main surface 11 on the interior side of the window glass 10 by, for example, adhering with double-sided tape and adhesive. The bracket device 100 also holds a camera 50. The camera 50 is an example of an imaging device, and captures an image of the area ahead of the vehicle through the window glass 10. The captured image can be used by, for example, a system such as the vehicle's ADAS (Advanced driver-assistance systems).

[0014] In this embodiment, the X-axis direction, the Y-axis direction, and the Z-axis direction respectively represent the horizontal direction of the window glass 10 of the vehicle, the vertical direction of the window glass 10, and the direction perpendicular to the surface of the window glass 10 (the normal direction). In many cases, the window glass 10 is installed at an angle with respect to the horizontal plane, but since the +Y-axis direction side is located higher than the -Y-axis direction side, the Y-axis direction is treated as the up-down direction of the window glass 10.

[0015] The +X-axis direction is the left side in the traveling direction of the vehicle, and the -X-axis direction is the right side in the traveling direction of the vehicle. The X-axis direction is the left-right direction in the traveling direction and the vehicle width direction. The +Y-axis direction is the upper side of the vehicle, and the -Y-axis direction is the lower side of the vehicle. For this reason, the +X-axis direction may be described as the left, the -X-axis direction as the right, the +Y-axis direction as the up, and the -Y-axis direction as the down. The +X-axis side (left side) is an example of a first side in the vehicle width direction, and the -X-axis side (right side) is an example of a second side in the vehicle width direction.

[0016] <Configuration of bracket device 100> The bracket device 100 includes a bracket 110. The bracket 110 is made of PBT (Poly Butylene Terephthalate) as an example, but may be made of a resin other than PBT or may be made of metal. When the bracket 110 is made of resin, it may be produced by injection molding as an example.

[0017] In the following, in addition to Fig. 1, Fig. 2A to Fig. 2C and Fig. 3 will be used for explanation. Fig. 2A to Fig. 2C are diagrams showing an example of the configuration of bracket 110. Fig. 3 is a diagram showing an example of the configuration of camera 50. Although camera 50 is not a component of bracket device 100, here, the configuration of camera 50 will first be briefly explained.

[0018] <Camera 50> The camera 50 has an imaging main body 51, a protrusion 52L, and two protrusions 52R. The camera 50 also has a convex portion 53 and a lens .

[0019] Here, a configuration in which camera 50 has one protrusion 52L and two protrusions 52R will be described, but camera 50 may have at least one protrusion 52L and at least two protrusions 52R. Protrusion 52L is an example of a first protrusion, and protrusion 52R is an example of a second protrusion.

[0020] The imaging body 51 is a part that has an imaging element (not shown) built in and generates imaging data, and has a substantially rectangular parallelepiped outer shape. The imaging body 51 is provided with a protrusion 52L, a protrusion 52R, a convex portion 53, and a lens 54.

[0021] Protrusion 52L protrudes from the left side surface of imaging main body 51 in the vehicle width direction, and is inserted into hole 112LA of bracket 110 when camera 50 is attached to bracket device 100. The length of protrusion 52L in the X-axis direction is longer than the length of two protrusions 52R in the X-axis direction. The reason for this will be described later with reference to Figures 4A to 4C.

[0022] The two protrusions 52R are spaced apart in the vertical direction (Y-axis direction) of the vehicle. The two protrusions 52R protrude from the right side surface in the vehicle width direction of the imaging main body 51, and are inserted into the two holes 112RA of the bracket 110, respectively, when the camera 50 is attached to the bracket device 100.

[0023] The protrusion 53 is an example of a first engagement portion, and is provided at approximately the center in the Y-axis direction at the end of the -X-axis direction side of the surface on the +Z-axis direction side of the imaging main body 51, as shown in Fig. 3. The protrusion 53 is a claw-shaped protrusion, and engages with a recess 114A (see Figs. 2A to 2C) of the leaf spring 114 of the bracket 110 when the camera 50 is attached to the bracket device 100. The recess 114A of the leaf spring 114 is an example of a second engagement portion.

[0024] The position of camera 50 in the X-axis direction is fixed relative to bracket 110 by engaging convex portion 53 with concave portion 114A of leaf spring 114. Note that, although a configuration in which convex portion 53 is an example of a first engagement portion and concave portion 114A is an example of a second engagement portion will be described here, an example of a first engagement portion may be a concave portion instead of convex portion 53, and in this case, an example of a second engagement portion may be a convex portion instead of concave portion 114A.

[0025] The lens is provided on the −Y axis direction side of the imaging main body 51. The camera 50 is capable of capturing an image through the lens .

[0026] <Bracket 110> Bracket 110 (see FIG. 2A) has base 111, left side wall 112L, right side wall 112R, support 113A, support 113B, support 113C, leaf spring 114, and sponge 115. Left side wall 112L is an example of a first wall, and right side wall 112R is an example of a second wall. Support 113A is an example of a first support, support 113B is an example of a second support, and support 113C is an example of a third support. Sponge 115 is an example of an elastic member. Supports 113A to 113C as a whole are an example of supports.

[0027] Bracket 110 is attached to main surface 11 (see FIG. 1) of window glass 10 on the indoor side, for example, by double-sided tape and adhesive. Here, bracket 110 will be described as a member to which camera 50 is attached, but bracket 110 may be larger and may be provided with an opening or cutout to avoid, for example, a rearview mirror.

[0028] <Base 111> Base 111 is a plate-like portion of bracket 110 that is approximately parallel to the XY plane and has projections and recesses, and has surface 111A, surface 111B, arrangement area 111C, hood 111D, and opening 111E. Surface 111A is an example of a first surface, and surface 111B is an example of a second surface.

[0029] The surface 111A is the surface facing the indoor main surface 11 of the window glass 10, and Figures 1, 2A and 2B show the position of the outer edge of the surface 111A. The surface 111B is the surface opposite to the surface 111A.

[0030] The arrangement area 111C is a three-dimensional area having a substantially rectangular parallelepiped shape in which the imaging main body unit 51 is arranged on the surface 111B side (inside the room) of the base 111. The hood 111D is a portion that serves as a hood for the lens 54 of the camera 50. The opening 111E is an opening provided in the base 111 above the hood 111D, and penetrates between the surfaces 111A and 111B. The lens 54 is provided in the opening 111E.

[0031] Hood 111D is provided facing the direction in which lens 54 of camera 50 receives light, and heats a heater built into it or attached to its surface to remove condensation, frost, ice, and the like that adheres to window glass 10. Note that hood 111D does not necessarily have to have a heater. In this case, as one example, a heatable conductive wire is provided on the main surface of window glass 10 on the indoor side to remove condensation, frost, ice, and the like that adheres to window glass 10.

[0032] <Left side wall 112L> The left side wall 112L protrudes from the base 111 to the left of the arrangement area 111C toward the room side (-Z axis direction side) and has a hole 112LA provided on the -Z axis direction side. The left side wall 112L is a plate-like member that is approximately rectangular when viewed from the YZ plane and has a small thickness in the X axis direction. The hole 112LA is an example of a first hole.

[0033] Hole 112LA penetrates left side wall 112L in the X-axis direction, and protrusion 52L of camera 50 is inserted into hole 112LA. The position of hole 112LA is aligned with the position of protrusion 52L of camera 50 when camera 50 is attached to bracket 110.

[0034] <Right side wall section 112R> The right side wall 112R protrudes from the base 111 to the right of the arrangement area 111C toward the room side (-Z axis direction side) and has two holes 112RA provided on the -Z axis direction side. The right side wall 112R is a plate-like member that is approximately rectangular when viewed from the YZ plane and has a small thickness in the X axis direction. The holes 112RA are an example of second holes.

[0035] The two holes 112RA are spaced apart in the vertical direction of the vehicle. The two holes 112RA penetrate the right side wall 112R in the X-axis direction, and the two protrusions 52R of the camera 50 are inserted into the two holes 112RA. The positions of the two holes 112RA are aligned with the positions of the two protrusions 52R of the camera 50 when the camera 50 is attached to the bracket 110.

[0036] The right side wall 112R is provided at a position in the vehicle width direction (X-axis direction) away from the left side wall 112L by a predetermined distance greater than the length of the imaging main body 51 in the vehicle width direction. This is because, when attaching the camera 50 to the bracket 110, the protrusion 52L is inserted into the hole 112LA of the left side wall 112L, and the camera 50 is slid to the right (-X-axis direction) relative to the left side wall 112L and the right side wall 112R in a state where the positions of the two protrusions 52R are aligned with the two holes 112RA of the right side wall 112R. The sliding amount of the camera 50 at this time is approximately equal to the predetermined distance. The predetermined distance is, for example, about 5 mm.

[0037] <Support part 113A> Support portion 113A is provided on surface 111B on the right side of left side wall portion 112L. Support portion 113A is, for example, three plate-like members standing up from surface 111B and extending in the X-axis direction, and serves as a slide base that supports imaging main body portion 51 so that it can slide in the vehicle width direction when camera 50 is attached to bracket 110. Providing support portion 113A on the right side of left side wall portion 112L allows camera 50 to slide stably in the X-axis direction relative to bracket 110.

[0038] When the camera 50 is attached to the bracket 110, the three support parts 113A come into contact with the three contact parts 51A (see FIG. 3) of the imaging main body part 51, for example, and support the imaging main body part 51 so as to be slidable in the vehicle width direction (X-axis direction). In FIG. 3, the three contact parts 51A are shown surrounded by a rectangle drawn with a dashed line. The three contact parts 51A have different heights in the Z-axis direction and are configured in a stepped shape. The three support parts 113A have different heights in the Z-axis direction corresponding to the three contact parts 51A. The three support parts 113A also have different positions in the Y-axis direction. The support part 113A located furthest to the -Y-axis direction among the three support parts 113A is located on the +X-axis direction side of the remaining two support parts 113A, and extends on the surface on the +Z-axis direction side of the protrusion part 52L.

[0039] The support portion 113A may function as a slide base that supports the imaging main body portion 51 on the right side of the left side wall portion 112L so as to be slidable in the vehicle width direction when the camera 50 is attached to the bracket 110. Therefore, each of the three support portions 113A may be integrated with the right side surface of the left side wall portion 112L, or may be spaced apart from the right side surface of the left side wall portion 112L. In Figs. 2A to 2C, as an example, the two support portions 113A other than the one support portion 113A located in the center in the Y-axis direction among the three support portions 113A are integrated with the right side surface of the left side wall portion 112L.

[0040] <Support part 113B> The support parts 113B are provided on the surface 111B on the left side of the right side wall part 112R, and are provided one each on the upper and lower sides of the leaf spring 114, i.e., next to the rear and front sides of the leaf spring 114 in the front-rear direction of the vehicle. As an example, the support parts 113B are two plate-shaped members that stand up from the surface 111B and extend in the X-axis direction, and are slide tables that support the imaging main body part 51 so that it can slide in the vehicle width direction when the camera 50 is attached to the bracket 110. By providing the support parts 113B one each on the upper and lower sides of the leaf spring 114, the camera 50 can be stably slid in the X-axis direction relative to the bracket 110.

[0041] When the camera 50 is attached to the bracket 110, the two support parts 113B come into contact with, for example, two contact parts 51B (see FIG. 3) of the imaging main body part 51, and support the imaging main body part 51 so as to be slidable in the vehicle width direction (X-axis direction). In FIG. 3, the two contact parts 51B are shown surrounded by a dashed-dotted rectangle. The two contact parts 51B are disposed on the lower and upper sides of the protrusion 53, respectively, and have the same height in the Z-axis direction. The two support parts 113B have the same height in the Z-axis direction corresponding to the two contact parts 51B. Furthermore, the two support parts 113B are also positioned at the same position in the X-axis direction.

[0042] When the camera 50 is attached to the bracket 110, the two support parts 113B guide the convex part 53 of the imaging main body part 51 in the -X axis direction along the extension direction (X axis direction) of the leaf spring 114. At this time, in order to be able to stably guide the abutment parts 51B on both sides of the convex part 53, the two support parts 113B are provided on both sides in the Y axis direction of the leaf spring 114. Note that, as long as the imaging main body part 51 can be stably guided, the support part 113B may be provided on only one side of the leaf spring 114 in the Y axis direction.

[0043] Furthermore, the support portion 113B may function as a slide base that supports the imaging main body portion 51 to be slidable in the vehicle width direction on the left side of the right side wall portion 112R when the camera 50 is attached to the bracket 110. For this reason, each of the two support portions 113B may be separated from the right side surface of the left side wall portion 112L as shown in Figures 2A to 2C, or may be integrated with the left side surface of the right side wall portion 112R.

[0044] <Support part 113C> Support portion 113C is provided on front surface 111B between support portion 113A and support portion 113B in the vehicle width direction. As an example, one support portion 113C is provided, and is located on the +Y axis direction side of opening 111E. As an example, support portion 113C is a plate-like member that stands up from front surface 111B and extends in the X axis direction, and is a slide base that supports imaging main body portion 51 slidably in the vehicle width direction when camera 50 is attached to bracket 110.

[0045] When the camera 50 is attached to the bracket 110, the support portion 113C abuts against the abutment portion 51C (see FIG. 3) of the imaging main body portion 51, for example, and supports the imaging main body portion 51 so as to be slidable in the vehicle width direction (X-axis direction). Since the abutment portion 51C is located at the center portion of the imaging main body portion 51 in the X-axis direction, the support portion 113C supports the center portion of the imaging main body portion 51 in the X-axis direction so as to be slidable in the vehicle width direction when the camera 50 is attached to the bracket 110. By providing the support portion 113C at the center portion in the X-axis direction between the support portions 113A and 113B, the camera 50 can be slid stably in the X-axis direction relative to the bracket 110.

[0046] Note that the support portion 113C only needs to function as a slide base that supports the imaging main body portion 51 so that the imaging main body portion 51 can slide in the vehicle width direction when the camera 50 is attached to the bracket 110. For this reason, two or more support portions 113C may be provided.

[0047] The above-mentioned support parts 113A to 113C may be provided between the left side wall part 112L and the right side wall part 112R. It is preferable that there are at least three support parts 113A to 113C, and it is preferable that the positions in the X-axis direction and the Y-axis direction are different from each other. This is because at least three points are sufficient to stably support the imaging main body part 51 with respect to the base part 111. It is preferable that the at least three support parts 113A to 113C are arranged so as to be located at the apexes of a triangle in a plan view on the surface 111B of the base part 111. This is to stably support the imaging main body part 51.

[0048] <Leaf spring 114> The leaf spring 114 is provided on the left side of the right side wall 112R between the two holes 112RA in the Y-axis direction. As shown in Fig. 2C, the leaf spring 114 stands in the -Z-axis direction from a base connected to the surface 111B of the base 111, and extends diagonally in the -Z-axis direction and the -X-axis direction toward a tip when viewed from the XZ plane. The leaf spring 114 has a protrusion that protrudes inclined in the -Z-axis direction on the base side from the recess 114A, and the recess 114A is provided next to the -X-axis side of the protrusion.

[0049] When camera 50 is slid in the -X axis direction relative to bracket 110 during mounting of camera 50 to bracket 110, the tip side of leaf spring 114 bends toward the +Z axis direction relative to the base as the inclined surface on the -X axis direction side of protrusion 53 overcomes the inclination on the +X axis direction side of recess 114A of leaf spring 114. Then, when protrusion 53 fits into recess 114A, it returns to the posture before bending, and recess 114A engages with protrusion 53. In this state, the position of camera 50 in the X axis direction relative to bracket 110 is fixed.

[0050] When removing camera 50 from bracket 110, pressing the tip of leaf spring 114 on the -X axis direction side toward the +Z axis direction will disengage convex portion 53 from concave portion 114A. In this state, camera 50 can be removed from bracket 110 by pulling camera 50 out from bracket 110 toward the +X axis direction.

[0051] Although leaf spring 114 is configured integrally with base 111, it may be a separate member from base 111. In this case, leaf spring 114 may be a metal spring. As described above, camera 50 may have a recess instead of protrusion 53, and leaf spring 114 may have a protrusion instead of recess 114A.

[0052] <Sponge 115> As an example, four sponges 115 are provided on the base 111. As an example, one sponge 115 provided on the +X-axis direction side and the +Y-axis direction side is provided on the right side of the left side wall 112L, on the +Y-axis direction side (upper side) of the support 113A. As an example, two sponges 115 provided on the -X-axis side are provided on the left side of the right side wall 112R, on the lower side of the support 113B located next to the lower side of the leaf spring 114, and on the upper side of the support 113B located next to the upper side of the leaf spring 114. The remaining sponge 115 is provided on the -Y-axis direction side (lower side) in the center in the X-axis direction of a portion of the surface 111B located on the back side of the hood 111D.

[0053] Each sponge 115 is attached with adhesive, double-sided tape, or the like to the surface on the -Z axis direction side of a protrusion that protrudes in a direction away from surface 111B in the -Z axis direction.

[0054] Sponge 115 is capable of elastic deformation. When camera 50 is attached to bracket 110, four sponges 115 abut against four abutment portions 51D shown in Fig. 3. As an example, sponge 115 has a thickness of 3 mm in the Z-axis direction, and is compressed to about 1.8 mm in thickness when pressed in the Z-axis direction.

[0055] When camera 50 is attached to bracket 110, if camera 50 is pressed against bracket 110 in the +Z-axis direction, sponge 115 contracts in the Z-axis direction. Then, when camera 50 is slid in the -X-axis direction relative to bracket 110 and protrusion 53 is accommodated in recess 114A of leaf spring 114, an elastic force (restoring force) that returns sponge 115 to the thickness before contraction acts, and camera 50 is fixed to bracket 110. In this state, sponge 115 biases imaging main body 51 in a direction away from surface 111B, so that camera 50 does not rattle against bracket 110 and is stably held. In this state, the position of camera 50 in the X-axis direction is fixed by recess 114A of leaf spring 114 and protrusion 53 of camera 50, and the position in the Y-axis direction is fixed by hole 112LA and two hole portions 112RA of bracket 110 and protrusion 52L and two protrusion portions 52R of camera 50.

[0056] Moreover, by providing sponge 115 on the right side of left side wall 112L and on the +Y axis direction side (upper side) of support 113A, the left side of camera 50 is stably held by bracket 110. Moreover, by providing two sponges 115 on the left side of right side wall 112R, on the lower side of support 113B located next to the lower side of leaf spring 114 and on the upper side of support 113B located next to the upper side of leaf spring 114, the right side of camera 50 is stably held by bracket 110. In particular, by arranging two sponges 115 on the lower and upper sides of leaf spring 114, the portion of the right side of camera 50 around protrusion 53 is stably held by bracket 110. Furthermore, by arranging the two sponges 115 below and above the two support parts 113B arranged below and above the leaf spring 114, the camera 50 is stably held on the bracket 110 with the portion around the protrusion 53 on the right side supported by the two support parts 113B. In this manner, the camera 50 can be stably attached to the bracket 110.

[0057] Although the bracket 110 has been described here as having four sponges 115, the number of sponges 115 may be any number as long as the same effect as the above-mentioned four sponges can be obtained. The number of sponges 115 is preferably three or more.

[0058] Also, here, a configuration has been described in which sponge 115 is attached to the surface on the -Z axis direction side of a protrusion protruding in a direction away from surface 111B in the -Z axis direction with adhesive, double-sided tape, etc. However, sponge 115 may be directly attached to surface 111B with adhesive, double-sided tape, etc.

[0059] Also, in the above, a configuration has been described in which sponge 115 is used as an elastic member. Since sponge 115 can obtain elastic deformation in the Z-axis direction and has small resistance when camera 50 is slid in the X-axis direction, it is suitable for a configuration in which camera 50 is slid in the X-axis direction and fixed to bracket 110, as in bracket device 100.

[0060] However, instead of sponge 115 as the elastic member, a rubber member, a foam member, or the like may be used.

[0061] <Method of attaching the camera 50 to the bracket device 100> 4A to 4C are diagrams illustrating an example of a method for attaching the camera 50 to the bracket device 100. FIG.

[0062] First, as shown in Fig. 4A, the protrusion 52L is inserted into the hole 112LA of the left side wall 112L. Although the protrusion 52L and the hole 112LA of the left side wall 112L are not visible in Fig. 4A, by inserting the protrusion 52L into the hole 112LA, the camera 50 becomes oblique with respect to the bracket 110 as shown in Fig. 4A. In order to insert the protrusion 52L into the hole 112LA, the left side of the imaging main body 51 is pressed against the bracket 110, and one sponge 115 provided on the +X-axis direction side and the +Y-axis direction side is contracted in the Z-axis direction, so that the camera 50 becomes oblique with respect to the bracket 110.

[0063] In this state, the remaining three sponges 115 are not contracted in the Z-axis direction. Also, the leaf spring 114 is not deformed in the +Z-axis direction. In this state, by inserting the protrusion 52L all the way into the hole 112LA, the left side surface of the imaging main body 51 abuts against the right side surface of the left wall 112L.

[0064] Next, as shown in Fig. 4B, the right side of the imaging main body 51 is pressed in the +Z-axis direction, and the positions of the two protrusions 52R in the Z-axis direction and the Y-axis direction are aligned with the two holes 112RA. In this state, the two protrusions 52R are not inserted into the two holes 112RA. Also, the leaf spring 114 is bent toward the +Z-axis direction, and the remaining three sponges 115 are contracted in the Z-axis direction.

[0065] Next, as shown in Fig. 4C, while pressing the right side of the imaging main body part 51 in the +Z-axis direction, the imaging main body part 51 is slid in the -X-axis direction, so that the two protrusions 52R are inserted into the two holes 112RA, respectively, and the right side surface of the imaging main body part 51 abuts against the left side wall of the right side wall part 112R. At this time, the protrusion part 53 of the imaging main body part 51 fits into the recess part 114A of the leaf spring 114, so that the leaf spring 114 returns to almost its original state from the state in which it was deformed in the +Z-axis direction. As a result, the camera 50 is fixed to the bracket 110 in the X-axis direction.

[0066] As described above, the left protrusion 52L of the camera 50 is longer than the two protrusions 52R on the right side, so even when slid in this manner, the protrusion 52L remains inserted in the hole 112LA.

[0067] Moreover, camera 50 is biased in the -Z-axis direction by the restoring forces of four sponges 115, and is therefore stably held in the Z-axis direction relative to bracket 110. The position of camera 50 in the Y-axis direction is fixed by protrusion 52L, hole 112LA, two protrusions 52R, and two holes 112RA.

[0068] Furthermore, when removing the camera 50 from the bracket 110, the following can be done. Press the tip of the leaf spring 114 on the -X-axis side in the +Z-axis direction to remove the convex portion 53 from the concave portion 114A, and while pressing the right side of the imaging main body portion 51 in the +Z-axis direction, slide the imaging main body portion 51 in the +X-axis direction, and the two protrusions 52R are removed from the two holes 112RA. This returns the camera 50 to the state shown in FIG. 4B. Furthermore, by pulling the protrusion 52L out of the hole 112LA of the left side wall portion 112L, the camera 50 can be removed from the bracket 110.

[0069] In this manner, in bracket device 100, camera 50 can be easily attached to and detached from bracket 110.

[0070] Therefore, it is possible to provide a bracket device 100 to which the camera 50 can be easily attached and detached.

[0071] Although an exemplary bracket device of the present disclosure has been described above, the present disclosure is not limited to the specifically disclosed embodiments, and various modifications and variations are possible without departing from the scope of the utility model registration claims.
