[0009] Embodiments of the present invention will be described below. Figure 1 illustrates the usage of hinge 3. Figures 2 and 3 illustrate the mounting state of hinge 3. Figure 2 shows the mounting state of the hinge 3 (first bracket 4) on the console box 1. In Figure 2, hatching is added to the end faces 121a and 122b on the near side of the paper to make the positions of the side walls 121 and 122 of the console box 1 easier to understand. Figure 3 shows the connection between the lid assembly 2 and the console box 1 via the hinge 3. Figure 3 schematically shows a cross-section along line AA in Figure 2. In the following explanation, the positional relationships of the console box 1, lid assembly 2, and hinge 3 components may be described using the X, Y, and Z directions in Figure 1. The X direction is along the width direction of the console box 1. The Z direction is along the longitudinal direction of the console box 1. The Y direction is along the opening direction of the storage section S1 of the console box 1.

[0010] In the vehicle, the console box 1 is installed between the driver's seat and the passenger seat, oriented along the front-to-rear direction of the vehicle. As shown in Figure 1, the console box 1 has a storage compartment S1 capable of accommodating items, located between the left and right side walls 121 and 122. The storage compartment S1 is open at the top of the console box 1.

[0011] The console box 1 includes a lid assembly 2 (lid member) for opening and closing the opening of the storage compartment S1. The lid assembly 2 is supported at the mounting portion 10 (see Figure 3) of the console box 1 via a hinge 3. As shown in Figure 3, the mounting portion 10 is located on one side (for example, the rear side of the vehicle) of the housing portion S1 in the Z direction (left-right direction in the figure). The mounting portion 10 is oriented along the Y direction. The lower end of the mounting portion 10 is connected to the bottom wall portion 11 of the housing portion S1. The hinge 3 (first bracket 4) is attached to the side of the mounting area 10 opposite to the housing S1 (right side in the diagram).

[0012] As shown in Figure 3, the console box 1 is a fixed component that is fixed to the vehicle body B. The lid assembly 2 is a movable component that is supported by the console box 1 via the hinge 3. The lid assembly 2 is rotatable around a central axis (rotation axis X) that is along the longitudinal direction of the shaft 30 of the hinge 3. As the lid assembly 2 rotates around the pivot axis X, the opening of the housing section S1 is opened and closed by the lid assembly 2.

[0013] As shown in Figure 1, the hinge 3 has a first bracket 4 fixed to the console box 1 side and a second bracket 5 fixed to the lid assembly 2 side. The first bracket 4 and the second bracket 5 are connected by a shaft 30 so as to be rotatable relative to each other.

[0014] Figure 4 is a diagram illustrating hinge 3. Figures 5 and 6 are diagrams illustrating the first bracket 4 of hinge 3. In Figure 4, the hinge 3 is shown divided into the first bracket 4, the second bracket 5, and the shaft 30. Figure 5(a) shows the first bracket 4 viewed from the front. Figure 5(b) shows a cross-section of the first bracket 4 cut along line AA in Figure 5(a). Figure 6 shows a magnified view of the base 41 of the first bracket 4.

[0015] As shown in Figure 4, the first bracket 4 has a plate-shaped base 41 and a pair of arm portions 42, 42 formed by bending both sides of the base 41 in the same direction in the width direction. As shown in Figures 5 and 6, the base portion 41 has a substantially rectangular shape in a front view. On both sides of the base portion 41 in the width direction (X direction), recesses 410, 410 are provided that are recessed toward the center line C4X. The recesses 410, 410 are located on one side edge 41a side (lower side in the figures) of the base portion 41 relative to the center line C4Y, and are provided in a symmetrical positional relationship with respect to the center line C4X. Here, the center line C4X is a straight line that passes through the center of the base 41 in the X direction (left-right direction in the figure) and also lies along the Y direction. The center line C4Y is a straight line that passes through the center of the base 41 in the Y direction (up-down direction in the figure) and also lies along the X direction. The center lines C4X and C4Y are perpendicular to each other.

[0016] On both sides of the base 41 in the width direction (X direction), the area on the side edge 41b side (upper side in the figure) of the recess 410 is folded towards the front of the paper, and this folded area forms the aforementioned arm portion 42. As shown in Figure 5(b), when viewed from the X direction, the arm portion 42 has a connection portion 421 with the base portion 41, an extension portion 422 extending from the connection portion 421 along the Y direction away from the side edge 41b of the base portion 41 (upward in the figure), an engaging portion 423 extending from the tip of the extension portion 422 away from the base portion 41 (rightward in the figure), and a connecting portion 424 having an insertion hole 424a. The shaft 30 (see Figure 4) passes through the insertion hole 424a when connecting the first bracket 4 and the second bracket 5. Therefore, the connecting portion 424 of the first bracket 4 is connected to the second bracket 5 at a position separated in the Z and Y directions when viewed from the base portion 41.

[0017] As shown in Figure 6, the first bracket 4 has a recess 411 on the side edge 41a of the base 41. The recess 411 is formed in the region where it intersects with the center line C4X, and is recessed on the side of the center line C4Y (upper side in the figure). The recess 411 extends along the center line C4X and is provided in a range that extends to the vicinity of the straight line L410 connecting the recesses 410, 410. When viewed from the Z direction, the tip region 411a of the recess 411 is semicircular. The positioning projection 16 (see Figure 3), which will be described later, is in contact with the tip region 411a of the recess 411.

[0018] Second through holes 44A and 44B are provided on both sides of the recess 411 in the X direction. The second through holes 44A and 44B are through holes for fasteners N (see Figure 1). Here, fasteners N are, for example, bolts or screws. When viewed from the Z direction, the second insertion holes 44A and 44B are positioned so that their positions are aligned in the Y direction. When viewed from the Z direction, the second insertion holes 44A and 44B are positioned symmetrically with respect to the center line C4X. The second insertion holes 44A and 44B are located closer to the center line C4X than the aforementioned recesses 410, 410. When viewed from the Z direction, the second insertion holes 44A and 44B are circular holes with a diameter r, and they penetrate the base 41 in the thickness direction (Z direction in the figure).

[0019] First insertion holes 43A and 43B for the fastener N are also provided on the side edge 41b of the base portion 41. When viewed from the Z direction, the first insertion holes 43A and 43B are aligned in the Y direction. When viewed from the Z direction, the first insertion holes 43A and 43B are positioned symmetrically with respect to the center line C4X. The first insertion holes 43A and 43B are located closer to the center line C4X than the second insertion holes 44A and 44B. When viewed from the Z direction, the first insertion holes 43A and 43B are circular holes with a diameter r and penetrate the base portion 41 in the thickness direction (Z direction in the figure). The distance L43 between the centers of the first insertion holes 43A and 43B in the X direction is smaller than the distance L44 between the centers of the second insertion holes 44A and 44B in the X direction (L43 <L44)。

[0020] Fitting holes 45A and 45B are provided on the side of the centerline C4Y (lower side in the figure) when viewed from the first insertion holes 43A and 43B. When viewed from the Z direction, the fitting holes 45A and 45B are positioned so that their centers C are at the same position in the Y direction. When viewed from the Z direction, the fitting holes 45A and 45B are positioned so that their centers C are symmetrical with respect to the center line C4X.

[0021] Viewed from the Z direction, the fitting holes 45A and 45B have first side edges 451, 451 on the long side and second side edges 452, 452 on the short side. The first side edges 451, 451 are spaced apart and parallel to each other. The second side edges 452, 452 are spaced apart and parallel to each other, and also connect the ends of the first side edges 451, 451. The connection between the first side edges 451, 451 and the second side edges 452, 452 is rounded.

[0022] When viewed from the Z direction, the fitting holes 45A and 45B are formed in a roughly rectangular shape. The fitting hole 45A is provided with its first side edges 451, 451 on the longer side oriented along the X direction (the axial direction of the rotation axis X). The fitting hole 45B is provided with its first side edges 451, 451 on the longer side oriented along the Y direction (the radial direction of the rotation axis X).

[0023] An opening 47 is provided between the fitting holes 45A and 45B. The opening 47 is located at a position that intersects with the center line C4X. In this embodiment, the distance L45 between the centers of the fitting holes 45A and 45B in the X direction is smaller than the distance L44 between the centers of the second insertion holes 44A and 44B in the X direction, and the distance L43 between the centers of the first insertion holes 43A and 43B in the X direction (L45 <L43<L44)。

[0024] Figure 7 is a schematic diagram illustrating the mounting area 10 on the console box 1 side. Figure 8 is an enlarged view illustrating the fastening state between the fitting projections 15A and 15B on the console box 1 side and the first bracket 4 of the hinge 3. Figures 9 and 10 are enlarged views illustrating the fitting protrusions 15A and 15B on the console box 1 side. Figure 7 schematically shows the mounting portion 10 on the console box 1 side as viewed from the mounting direction (Z direction) of the hinge 3 (first bracket 4). In Figure 8, the portion of the first bracket 4 at the mounting area 10 on the console box 1 side that is hidden on the back of the paper is indicated by a hidden line. Furthermore, to make the positions of the fitting protrusions 15A and 15B easier to understand, intersecting hatching is added to the portions of the fitting protrusions 15A and 15B.

[0025] As shown in Figure 7, the mounting portion 10 of the console box 1 is provided with boss portions 13A, 13B, 14A, and 14B for screwing in the fastener N, and fitting projections 15A and 15B that fit into the fitting holes 45A and 45B on the first bracket 4 side.

[0026] When viewed from the Z direction, the boss portions 13A and 13B are aligned in the Y direction. The boss portions 13A and 13B are spaced apart in the X direction. When viewed from the Z direction, the boss portions 13A and 13B form a cylindrical shape with a screw hole 13a. When attaching the first bracket 4 to the mounting part 10, a fastener N (see Figure 2) that has passed through the first insertion holes 43A and 43B of the first bracket 4 is screwed into the screw hole 13a, thereby fixing the first bracket 4 to the upper surface of the boss portions 13A and 13B.

[0027] The bosses 13A and 13B are positioned symmetrically with respect to the center line C10, which passes through the center of the mounting area 10 in the width direction (X direction). Viewed from the Z direction, the boss portions 13A and 13B are connected by a reinforcing rib 171 extending in the X direction. The boss portions 13A and 13B are provided at offset positions from one end 171a and the other end 171b of the reinforcing rib 171, respectively. The distance L13 between the centers of the boss portions 13A and 13B is the same as the distance L43 between the centers of the first insertion holes 43A and 43B (see Figure 6).

[0028] When viewed from the Z direction, the boss portions 14A and 14B are aligned in the Y direction. The boss portions 14A and 14B are spaced apart in the X direction. When viewed from the Z direction, the boss portions 14A and 14B form a cylindrical shape with a screw hole 14a. When attaching the first bracket 4 to the mounting part 10, a fastener N (see Figure 2) that has passed through the second insertion holes 44A and 44B of the first bracket 4 is screwed into the screw hole 14a, thereby fixing the first bracket 4 to the upper surface of the boss portions 14A and 14B.

[0029] The bosses 14A and 14B are positioned symmetrically with respect to the center line C10, which passes through the center of the mounting area 10 in the width direction (X direction). A projection 16 is provided between boss portion 14A and boss portion 14B. The projection 16 is located on the center line C10. The projection 16 protrudes in the Z direction away from the mounting portion 10.

[0030] Viewed from the Z direction, the projection 16 and the boss portions 14A and 14B are connected by a reinforcing rib 172 extending in the X direction. The boss portions 14A and 14B are provided at offset positions from one end 172a and the other end 172b of the reinforcing rib 172, respectively. The distance L14 between the centers of the boss portions 14A and 14B is the same as the distance L44 between the centers of the second insertion holes 44A and 44B (see Figure 6). Furthermore, the distance Lb between the centers of boss portions 14A and 14B and boss portions 13A and 13B in the Y direction is the same as the distance Lb between the centers of the first insertion holes 43A and 43B and the second insertion holes 44A and 44B (see Figure 6).

[0031] When viewed from the Z direction, the fitting protrusions 15A and 15B are provided at intervals in the X direction. The fitting protrusions 15A and 15B are provided in a symmetrical positional relationship with the center line C10 passing through the aforementioned protrusion 16 in between. As shown in Figures 9 and 10, the fitting projections 15A and 15B have a pair of first side wall portions 151, 151 and a pair of second side wall portions 152, 152.

[0032] As shown in Figure 9, in the fitting projection 15A, a pair of first side wall portions 151, 151 are provided parallel to each other with a gap in the Y direction (radial direction of the rotation axis X). The pair of first side wall portions 151, 151 are provided in a direction along the X direction. The pair of second side wall portions 152, 152 are provided parallel to each other with a gap in the X direction (axial direction of the rotation axis X). The pair of second side wall portions 152, 152 are provided in a direction along the Y direction.

[0033] As shown in Figure 10, the fitting projection 15B has a pair of first side wall portions 151, 151 that are spaced apart in the X direction (axial direction of the rotation axis X) and are parallel to each other. The pair of first side wall portions 151, 151 are oriented along the Y direction. The pair of second side wall portions 152, 152 are spaced apart in the Y direction (radial direction of the rotation axis X) and are parallel to each other. The pair of second side wall portions 152, 152 are oriented along the X direction.

[0034] In the fitting projections 15A and 15B, a pair of second side wall portions 152, 152 connect the ends of a pair of first side wall portions 151, 151, respectively. When viewed from the Z direction, the fitting projections 15A and 15B have a roughly rectangular shape. The fitting projection 15A is provided with its long side (first side wall portion 151, 151) oriented along the X direction. The fitting projection 15B is provided with its long side (first side wall portion 151, 151) oriented along the Y direction.

[0035] Multiple ribs are provided on the outer circumference of the mating projections 15A and 15B. The arrangement of the ribs differs when viewed from the Z direction on the mating projections 15A and 15B. In the fitting projection 15A, first ribs 155, 155 are provided on the first side walls 151, 151 on the long side. The first ribs 155, 155 are spaced apart in the X direction and are parallel to each other. One of the first ribs 155 extends in the Y direction along the extension of the second side wall 152. The other first rib 155 extends in the Y direction from a position offset from the other second side wall 152 towards the first second side wall 152 (left side in the figure).

[0036] The protruding length L155 of the first rib 155 is set such that the length Ly15A from one first rib 155 to the other first rib 155 in the Y direction is the same as or slightly larger than the Y-direction length Ly45A of the fitting hole 45A (see Figure 5).

[0037] In the fitting projection 15A, second ribs 156, 156 are provided on the second side walls 152, 152 on the short side. The second ribs 156, 156 are located in the center of the second side walls 152, 152 in the Y direction and are provided aligned in the Y direction. The second ribs 156, 156 extend linearly from the outer circumference of the second sidewalls 152, 152. The protruding length L156 of the second ribs 156 is set such that the length Lx15A from one second rib 156 to the other second rib 156 in the X direction is the same as or slightly larger than the length Lx45A in the Y direction of the fitting hole 45A (see Figure 5).

[0038] As shown in Figure 10, the fitting projection 15B has first ribs 155, 155 on the first side walls 151, 151 on the long side. The first ribs 155, 155 are spaced apart in the Y direction (radial direction of the rotation axis X) and are parallel to each other. One of the first ribs 155 extends in the X direction from a position offset from one of the second side walls 152 toward the other second side wall 152 (downward in the figure). The other first rib 155 extends in the X direction from a position offset from the other side wall 152 toward the one side wall 152 (upward in the figure).

[0039] The protruding length L155 of the first rib 155 is set such that the length Lx15B ​​from one first rib 155 to the other first rib 155 in the X direction is the same as or slightly larger than the X-direction length Lx45B of the fitting hole 45B (see Figure 5).

[0040] In the fitting projection 15B, second ribs 156, 156 are provided on the second side walls 152, 152 on the short side. One second rib 156 extends linearly in the Y direction from the outer circumference of the other first side wall 151 side (right side in the figure) rather than the center of the second side wall 152 in the X direction. The other second rib 156 extends linearly in the Y direction from the outer circumference of the other first side wall 151 side (right side in the figure) rather than the center of the second side wall 152 in the X direction. The protruding length L156 of the second rib 156 is set such that the length Ly15B from one second rib 156 to the other rib in the Y direction is the same as or slightly larger than the Y-direction length Ly45B of the fitting hole 45B (see Figure 5).

[0041] When the first bracket 4 of the hinge 3 is attached to the mounting area 10 on the console box 1 side, the fitting projections 15A and 15B are fitted into the fitting holes 45A and 45B on the first bracket 4 side, respectively. As shown in Figures 8 and 9(b), in the fitting projection 15A, the first ribs 155, 155 press against the inner circumference of the first side edges 451, 451 on the long side of the fitting hole 45A, while the second ribs 156, 156 press against the inner circumference of the second side edges 452, 452 on the short side of the fitting hole 45A. Similarly, as shown in Figures 8 and 10(b), in the fitting projection 15B, the first ribs 155, 155 press against the inner circumference of the first side edges 451, 451 on the long side of the fitting hole 45A, while the second ribs 156, 156 press against the inner circumference of the second side edges 452, 452 on the short side of the fitting hole 45A. As a result, the movement of the first bracket 4 in the X, Y, and Z directions is restricted by the first rib 155 and the second rib 156, which press against the inner circumference (first side edge 451 and second side edge 452) of the fitting hole 45A.

[0042] Here, when the fastener N located above the fitting hole 45B in Figure 8 is screwed into the boss portion 13B of the mounting portion 10, a rotational torque in a clockwise direction CW around the fastener N (rotation center C13B) acts on the fitting projection 15B fitted into the fitting hole 45B of the first bracket 4 (see arrow in Figure 8).

[0043] Here, the fitting hole 45A is positioned with the first side edges 451, 451 on the long side aligned with the X direction. The fitting hole 45B is positioned with the first side edges 451, 451 on the long side aligned with the Y direction. The two first ribs 155, 155 are pressed against the first side edges 451, 451 on the long side. Therefore, when fastening with the fastener N, if a torque is applied to the first bracket 4 that rotates it clockwise around the rotation center C13B of the fastener N, the two first ribs 155, 155 provided on the first side wall portion 151 on the long side of the fitting projections 15A, 15B press against the first side edge 451 of the fitting hole 45A and the first side edge 451 of the fitting hole 45B. In this case, the pressing force is distributed to the two first ribs 155, 155. If only one rib presses against the first side edge 451, stress concentration may cause the rib to bend, and the fitting projection may be accommodated with looseness in the fitting hole. By configuring it as described above, the possibility of the fitting protrusions 15A and 15B being loosely fitted into the fitting holes 45A and 45B can be reduced.

[0044] [Second bracket] Figures 11 and 12 illustrate the second bracket 5 of the hinge 3. Figure 11 is a plan view of the second bracket 5. Figure 12(a) is a cross-sectional view of the second bracket 5 taken along line AA in Figure 11. Figure 12(b) is a side view of the second bracket 5 as seen from the direction of arrow BB in Figure 11.

[0045] As shown in Figures 4 and 11, the second bracket 5 has a plate-shaped base 51 and a pair of side wall portions 52, 52 formed by bending both sides of the base 51 in the same direction in the width direction (X direction). As shown in Figure 11, one side edge 51a and the other side edge 51b of the base 51 are parallel to each other in the Y direction (vertical direction in the figure). The width L51a of side edge 51a in the X direction is narrower than the width L51b of side edge 51b in the X direction.

[0046] The tips 52a, 52a of the side wall portions 52, 52 reach a position that is a distance L52 in the Y direction from the side edge 51a of the base portion 51. As shown in Figure 12(b), the side wall portions 52, 52 have support arms 521, 521 for supporting the shaft 30 in the region on the tip 52a, 52a side of the side edge 51a of the base portion 51. The support arms 521 extend linearly in the Y direction from a position offset in the Z direction from the base portion 51. The tip 52a side of the side wall portion 52 bulges outwards from the base portion 51 (to the left in the figure). An insertion hole 521a for the shaft 30 is provided in the bulging portion of the side wall portion 52.

[0047] As shown in Figure 11, slits 510, 510 are provided on the side edge 51a of the base portion 51 at a position offset from the side wall portions 52, 52 toward the center line C5X. The slits 510, 510 extend linearly toward the side edge 51b (upper side in the figure) along the center line C5X. In the second bracket 5, the region between the slits 510, 510 forms a support piece 56 for supporting the shaft 30. As shown in Figure 12(a), the support piece 56 is formed by bending a strip-shaped piece extending from the base 51. The support piece 53 has a support portion 562 parallel to the base 51 and a connecting portion 561 that connects the base 51 and the support portion 562. The support portion 562 is located on the opposite side (left side in the figure) from the base portion 51 when viewed from the through hole 521a. In the Y direction, the tip 562a of the support portion 562 is located between the tip 52a of the side wall portion 52 and the side edge 51a of the base portion 51.

[0048] A steel clamp 57 supporting the shaft 30 is fixed to the base 51 side of the connecting portion 561 with a headed screw N1. The steel clamp 57 has a basic shape in which overlapping strip-shaped members 571, 571 are wrapped around the outer circumference of the shaft 30. The headed screw N1 penetrates the area at the end of the strip-shaped members 571, 571 and the support portion 562. When the headed screw N1 is tightened, the area of ​​the steel clamp 57 wrapped around the shaft 30 presses against the outer circumference of the shaft 30, and the shaft 30 is held in a position where it cannot be displaced relative to the support piece 56.

[0049] As shown in Figure 11, the base portion 51 is provided with first insertion holes 53A and 53B for the fastener N on one side edge 51a (lower side in the figure) relative to the center line C5Y in the Y direction. In the Y direction, the first insertion holes 53A and 53B are located between the center line C5Y and the slits 510, 510. When viewed from the Z direction, the first insertion holes 53A and 53B are positioned so that their positions are aligned in the Y direction. The first insertion holes 53A and 53B are positioned symmetrically with respect to the center line C5X. When viewed from the Z direction, the first insertion holes 53A and 53B are circular holes with a diameter r, and they penetrate the base 51 in the thickness direction (Z direction in the figure).

[0050] Second insertion holes 54A and 54B for fasteners are also provided on the side edge 51b of the base portion 51. When viewed from the Z direction, the second insertion holes 54A and 54B are positioned so that their positions are aligned in the Y direction. When viewed from the Z direction, the second insertion holes 54A and 54B are positioned symmetrically with respect to the center line C5X. When viewed from the Z direction, the second insertion holes 54A and 54B are circular holes with a diameter r, and they penetrate the base portion 51 in the thickness direction (Z direction in the figure). The distance L54 between the centers of the second insertion holes 54A and 54B in the X direction is greater than the distance L53 between the centers of the first insertion holes 53A and 53B in the X direction (L54 > L53). When viewed from the Z direction, the second insertion holes 54A and 54B are located on the extension of the support arm portion 521. Therefore, the width L51b in the X direction of the region in the base portion 51 where the second insertion holes 54A and 54B are provided is wider than the width L51a in the X direction of the region where the first insertion holes 53A and 53B are provided.

[0051] Fitting holes 55A and 55B are provided on the side of the centerline C5Y when viewed from the second insertion holes 54A and 54B. When viewed from the Z direction, the fitting holes 55A and 55B are arranged so that the position of the center C of the fitting holes 55A and 55B is the same in the Y direction. When viewed from the Z direction, the fitting holes 55A and 55B are arranged so that the position of the center C of the fitting holes 55A and 55B is symmetrical with respect to the center line C5X.

[0052] When viewed from the Z direction, the fitting holes 55A and 55B are formed in a roughly rectangular shape from first side edges 551, 551 that are spaced apart and parallel to each other in the X direction, and second side edges 552, 552 that connect the ends of the first side edges 551, 551. The second side edges 552, 552 are spaced apart and parallel to each other in the Y direction. The connection between the first side edges 551, 551 and the second side edges 552, 552 is rounded. The fitting holes 55A and 55B are provided with the first side edges 551, 551 on the longer side aligned with the Y direction.

[0053] In this embodiment, the distance L55 between the centers of the fitting holes 55A and 55B in the X direction is smaller than the distance L54 between the centers of the second insertion holes 54A and 54B in the X direction, and larger than the distance L53 between the centers of the first insertion holes 53A and 53B in the X direction (L54 <L55<L53)。

[0054] Figure 13 is a schematic diagram illustrating the mounting portion 20 on the lid assembly 2 side. Figure 13 schematically shows the mounting portion 20 on the lid assembly 2 side as viewed from the mounting direction (Z direction) of the second bracket 5.

[0055] As shown in Figure 13, the mounting portion 20 on the lid assembly 2 side is provided with boss portions 23A, 23B, 24A, and 24B for screwing in the fastener N, and fitting projections 25A and 25B that fit into the fitting holes 55A and 55B on the second bracket 5 side.

[0056] When viewed from the Z direction, the bosses 23A and 23B are aligned in the Y direction. The bosses 23A and 23B are spaced apart in the X direction. When viewed from the Z direction, the bosses 23A and 23B form a cylindrical shape with a screw hole 23a. When attaching the second bracket 5 to the mounting part 20, the fastener N, which has passed through the first insertion holes 53A and 53B of the second bracket 5, is screwed into the screw hole 23a, thereby fixing the second bracket 5 to the upper surface of the bosses 23A and 23B.

[0057] The bosses 23A and 23B are positioned symmetrically with respect to the center line C20, which passes through the center of the mounting portion 20 in the width direction. The boss sections 23A and 23B are connected by reinforcing ribs 271 extending in the X direction. Ribs 272, 272 extending perpendicular to the reinforcing ribs 271 are connected to the outer circumference of the boss sections 23A and 23B. The distance L23 between the centers of bosses 23A and 23B is the same as the distance L53 between the centers of the first insertion holes 53A and 53B (see Figure 11).

[0058] When viewed from the Z direction, the bosses 24A and 24B are aligned in the Y direction. The bosses 24A and 24B are spaced apart in the X direction. When viewed from the Z direction, the bosses 24A and 24B form a cylindrical shape with a screw hole 24a. When attaching the second bracket 5 to the mounting part 20, the fastener N, which has passed through the second insertion holes 54A and 54B of the second bracket 5, is screwed into the screw hole 24a, thereby fixing the second bracket 5 to the upper surface of the bosses 24A and 24B.

[0059] Boss sections 24A and 24B are positioned symmetrically with the center line C20 in between. Viewed from the Z direction, boss sections 24A and 24B are connected by reinforcing ribs 273 extending in the X direction. Ribs 274, 274 extending perpendicular to ribs 273 are connected to the outer circumference of boss sections 24A and 24B. The distance L24 between the centers of bosses 24A and 24B is the same as the distance L54 between the centers of the second insertion holes 54A and 54B (see Figure 11). Furthermore, the distance Ly2 between the centers of bosses 23A, 23B and bosses 24A, 24B in the Y direction is the same as the distance Ly5 between the centers of the first insertion holes 53A, 53B and the second insertion holes 54A, 54B (see Figure 11).

[0060] Fitting protrusions 25A and 25B are provided between boss portions 23A and 23B and boss portions 24A and 24B in the Y direction. When viewed from the Z direction, the fitting protrusions 25A and 25B are spaced apart in the X direction. The fitting protrusions 25A and 25B are positioned symmetrically with the center line C20 in between.

[0061] Figures 14 and 15 illustrate the fitting projections 25A and 25B on the lid assembly 2. Figure 16 is an enlarged view illustrating the fastening state between the fitting projections 25A and 25B on the lid assembly 2 and the second bracket 5 of the hinge 3. As shown in Figures 14 and 15, the fitting projections 25A and 25B have a pair of first side wall portions 251, 251 and a pair of second side wall portions 252, 252.

[0062] In the fitting projections 25A and 25B, a pair of first side wall portions 251, 251 are provided parallel to each other with a gap in the X direction. The pair of first side wall portions 251, 251 are provided in a direction along the Y direction. The pair of second side wall portions 252, 252 are provided parallel to each other with a gap in the Y direction. The pair of second side wall portions 252, 252 are provided in a direction along the X direction.

[0063] Multiple ribs are provided on the outer circumference of the fitting projections 25A and 25B. The arrangement of the ribs differs when viewed from the Z direction on the fitting projections 25A and 25B. In the fitting projection 25A, second ribs 256, 256 are provided in the center of the second side wall portions 252, 252 in the X direction. The second ribs 256, 256 extend in the Y direction from the outer circumference of the second side wall portions 252, 252.

[0064] The protruding length L256 of the first rib 255 is set such that the length Ly25A from one second rib 256 to the other second rib 256 in the Y direction is the same as or slightly larger than the Y-direction length Ly55A of the fitting hole 55A (see Figure 16).

[0065] In the fitting projection 25A, first ribs 255, 255 are provided on the first side walls 251, 251, respectively. The first ribs 255, 255 are spaced apart in the Y direction and are parallel to each other. One of the first ribs 255 extends in the X direction from a position offset from one second side wall 252 toward the other second side wall 252 (downward in the figure). The other first rib 255 extends in the X direction from a position offset from the other second side wall 252 toward the one second side wall 252 (upward in the figure).

[0066] The protruding length L255 of the first rib 255 is set such that the length Lx25A from one first rib 255 to the other first rib 255 in the X direction is the same as or slightly larger than the length Lx55A of the fitting hole 55A in the X direction (see Figure 16).

[0067] As shown in Figure 15, the fitting projection 25B is provided with second ribs 256, 256 on the second side walls 252, 252, respectively. The second ribs 256, 256 are spaced apart in the X direction and are parallel to each other. One second rib 256 extends in the Y direction from a position offset from one first side wall 251 toward the other first side wall 251 (right side in the figure). The other second rib 256 extends in the Y direction from a position offset from the other first side wall 251 toward the one first side wall 251 (left side in the figure).

[0068] The protruding length L256 of the second rib 256 is set such that the length Ly25B from one second rib 256 to the other second rib 256 in the Y direction is the same as or slightly larger than the length Ly55B in the X direction of the fitting hole 55B (see Figure 16).

[0069] In the fitting projection 25B, first ribs 255 are provided on the first side walls 251, 251. The first ribs 255 extend in the X direction from the outer circumference of the first side walls 251, 251. When viewed from the Z direction, the first rib 255 on one side and the first rib 255 on the other side are offset in the Y direction. The protruding length L255 of the first rib 255 is set such that the length Lx25B from one first rib 255 to the other first rib 255 in the X direction is the same as or slightly larger than the length Lx55B of the fitting hole 55B in the X direction (see Figure 16).

[0070] When the second bracket 5 of the hinge 3 is attached to the mounting portion 20 on the lid assembly 2 side, the fitting projections 25A and 25B are fitted into the fitting holes 55A and 55B on the second bracket 5 side, respectively. In this configuration, the first ribs 255, 255 of the fitting projection 25A press against the inner circumference of the first side edges 551, 551 on the long side of the fitting hole 55A, while the second ribs 256, 256 press against the inner circumference of the second side edges 552, 552 on the short side of the fitting hole 55A. Similarly, in the fitting projection 25B, the first ribs 255, 255 press against the inner circumference of the first side edges 551, 551 on the long side of the fitting hole 55A, while the second ribs 256, 256 press against the inner circumference of the second side edges 552, 552 on the short side of the fitting hole 55B. As a result, the movement of the second bracket 5 in the X, Y, and Z directions is restricted by the first rib 255 and the second rib 256 that press against the inner circumference (first side edges 551, 552) of the fitting hole 55A, and by the first rib 255 and the second rib 256 that press against the inner circumference (first side edges 551, 552) of the fitting hole 55B.

[0071] Here, when the fastener N, located above the fitting hole 55B in Figure 16, is screwed into the boss portion 24B of the mounting portion 20, a torque in a clockwise direction CW around the fastener N (rotation center C24B) acts on the second bracket 5 (see arrow in Figure 16).

[0072] Here, the fitting holes 55A and 55B are arranged with the first side edges 551, 551 on the longer side aligned with the Y direction, and the second side edges 552, 552 on the shorter side aligned with the X direction. The fitting projection 25A is provided with two first ribs 255 and one second rib 256, while the fitting projection 25B is provided with one first rib 255 and two second ribs 256. Therefore, when fastening with the fastener N, if a torque is applied to the first bracket 4 that rotates it clockwise around the rotation center C24B of the fastener N, In the fitting projection 25A, two first ribs 255, 255 are pressed against the first side edge 551 on the longer side, and in the fitting projection 25B, two second ribs 256, 256 are pressed against the second side edge 552 on the shorter side. This distributes the stress acting on the fitting projections 25A and 25B from the first and second side edges 551 and 552. If only one rib presses against the first and second side edges 551 and 552, stress concentration may cause the rib to bend, resulting in the fitting projection being accommodated loosely in the fitting hole. By configuring it as described above, the possibility of the fitting projection being accommodated loosely in the fitting hole can be reduced.

[0073] Here, the fitting configuration between the fitting projections 15A and 15B of the mounting portion 10 on the console box 1 side and the fitting holes 45A and 45B of the first bracket 4 of the hinge 3, the arrangement of the boss portions 13A and 13B and the first insertion holes 43A and 43B, and the arrangement of the boss portions 14A and 14B and the second insertion holes 44A and 44B correspond to the mounting structure of the hinge 3 on the console box 1 side. The fitting configuration between the fitting projections 25A and 25B of the mounting portion 20 on the lid assembly 2 side and the fitting holes 55A and 55B of the second bracket 5 of the hinge 3, the arrangement of the boss portions 23A and 23B and the first insertion holes 53A and 53B, and the arrangement of the boss portions 24A and 24B and the second insertion holes 54A and 54B correspond to the mounting structure of the hinge 3 on the lid assembly 2 side. By adopting the mounting structure of the hinge 3 described above, the relative movement of the pivot axis X of the first bracket 4 in the axial and radial directions at the mounting portion 10, and the relative movement of the pivot axis X of the second bracket 5 in the axial and radial directions at the mounting portion 20 can be effectively suppressed. This is expected to improve the support stability of the hinge 3 at the mounting points 10 and 20 of the hinge 3.

[0074] Furthermore, in the above-described embodiment, the number of first ribs 155 provided on the first side wall portion 151 and the number of second ribs 156 provided on the second side wall portion 152 of the fitting projections 15A and 15B are made different according to the direction of action of the rotational torque caused by tightening the fastener N. This effectively suppresses the occurrence of gaps or deformations that cause looseness between the fitting projections 15A, 15B and the fitting holes 45A, 45B when fixing the first bracket 4 of the hinge 3 to the mounting portion 10 on the console box 1 side with the fastener N, due to the rotational torque caused by tightening the fastener N.

[0075] Furthermore, in the fitting projections 25A and 25B, the number of first ribs 255 that fit onto the first side edge 551 of the fitting holes 55A and 55B, and the number of second ribs 256 that fit onto the second side edge 552, are made different according to the direction of action of the rotational torque caused by the tightening of the fastener N. This effectively suppresses the occurrence of gaps or deformations that cause looseness between the fitting projections 25A, 25B and the fitting holes 55A, 55B, due to the rotational torque caused by tightening the fastener N when fixing the second bracket 5 of the hinge 3 to the mounting portion 20 on the lid assembly 2 side with the fastener N. This also contributes to the expected improvement in the support stability of the hinge 3 at the mounting points 10 and 20.

[0076] As described above, the hinge mounting structure according to this embodiment has the following configuration. (1) The mounting structure of the hinge 3 is a mounting structure of the hinge 3 on the console box 1 and the lid assembly 2 that connects the console box 1 (first member) and the lid assembly 2 (second member) so that they can rotate relative to each other around a common pivot axis X. Hinge 3 is, A first bracket 4 is fixed to the mounting portion 10 of the console box 1 (first component) by fasteners N, The second bracket 5 is fixed to the mounting portion 20 of the lid assembly 2 (second member) by fasteners N, It includes a shaft 30 that connects the first bracket 4 and the second bracket 5 so that they can rotate relative to each other around the pivot axis X. The first bracket 4 is, A pair of first insertion holes 43A and 43B (first insertion holes) are arranged at intervals in the axial direction of the pivot axis X, It has a pair of second insertion holes 44A and 44B (second insertion holes) that are spaced apart in the axial direction of the pivot axis X. The second bracket 5 is, A pair of first insertion holes 53A and 53B (first insertion holes) are arranged at intervals in the axial direction of the pivot shaft X, It has a pair of second insertion holes 54A and 54B (second insertion holes) that are spaced apart in the axial direction of the pivot axis X. The pair of first insertion holes 43A and 43B and the pair of second insertion holes 44A and 44B are provided spaced apart in the radial direction of the pivot axis X. The pair of first insertion holes 53A and 53B and the pair of second insertion holes 54A and 54B are provided spaced apart in the radial direction of the pivot axis X. In the radial direction of the pivot axis X, the pair of second insertion holes 44A and 44B are located further from the pivot axis X than the pair of first insertion holes 43A and 43B. In the radial direction of the pivot axis X, the pair of second insertion holes 54A and 54B are located further from the pivot axis X than the pair of first insertion holes 53A and 53B. The distance L44 (spacing) between the centers of a pair of second insertion holes 44A and 44B in the axial direction of the pivot axis X is wider than the distance L43 (spacing) between the centers of a pair of first insertion holes 43A and 43B. The distance L54 (spacing) between the centers of a pair of second insertion holes 54A and 54B in the axial direction of the pivot axis X is wider than the distance L53 (spacing) between the centers of a pair of first insertion holes 53A and 53B.

[0077] In the two components (console box 1 and lid assembly 2) connected via the hinge 3, when the two components are displaced relative to each other, stresses caused by the relative displacement act on the mounting portion 10 of the first bracket 4 on the console box 1 and the mounting portion 20 of the second bracket 5 on the lid assembly 2. In this case, the first bracket 4 and the second bracket 5 are also subjected to stress in a direction that causes them to tilt with respect to the rotation axis X. However, this stress is greater in the second insertion holes 44A, 44B and 54A, 54B, which are located further away from the rotation axis X, than in the first insertion holes 43A, 43B and 53A, 53B. As described above, by making the distance L44 between the centers of the second insertion holes 44A and 44B and the distance L54 between the centers of the second insertion holes 54A and 54B wider than the distance L43 between the centers of the first insertion holes 43A and 43B and the distance L53 between the centers of the first insertion holes 53A and 53B, the resistance to stress on the side of the second insertion holes 44A and 44B and the second insertion holes 54A and 54B can be increased. This is expected to improve the support stability of the hinge 3 at the mounting points 10 and 20 of the hinge 3.

[0078] (2) In (1) above, The lid assembly 2 (second member) is provided so as to be displaceable relative to the console box 1 (first member) via a hinge 3. The distance L44 between the centers of the second insertion holes 44A and 44B in the axial direction of the pivot shaft X5 is greater for the second insertion holes 54A and 54B on the lid assembly 2 side than for the second insertion holes 44A and 44B on the console box 1 side.

[0079] When the lid assembly 2 is displaced relative to the console box 1, the stress acting on the hinge 3 increases as it moves radially away from the shaft 30 (rotation axis X). Furthermore, when the movable component, the lid assembly 2, undergoes relative displacement with respect to the fixed component, the second bracket 5 on the lid assembly 2 side experiences greater stress than the first bracket 4 on the console box 1 side. With the above configuration, the stress resistance of the second bracket 5 on the lid assembly 2 side can be increased. Therefore, an improvement in the support stability of the hinge 3 (second bracket 5) at the mounting portion 20 of the hinge 3 can be expected.

[0080] (3) In (1) or (2) above, The first bracket 4 has fitting holes 45A and 45B for the fitting protrusions 15A and 15B on the console box 1 side. The second bracket 5 has fitting holes 55A and 55B for the fitting projections 25A and 25B on the lid assembly 2 side. The fitting holes 45A and 45B are spaced apart in the axial direction of the pivot axis X. The fitting holes 55A and 55B are spaced apart in the axial direction of the pivot axis X. In the radial direction of the pivot axis X, the fitting holes 45A and 45B are located between the first insertion holes 43A and 43B and the second insertion holes 44A and 44B. In the radial direction of the pivot axis X, the fitting holes 55A and 55B are located between the first insertion holes 53A and 53B and the second insertion holes 54A and 54B.

[0081] The fitting protrusions 15A and 15B on the console box 1 side fit into the fitting holes 45A and 45B on the first bracket 4 side, respectively, thereby improving the support stability of the first bracket 4 in the console box 1. The fitting protrusions 25A and 25B on the lid assembly 2 side fit into the fitting holes 55A and 55B on the second bracket 5 side, respectively, thereby improving the support stability of the second bracket 5 in the lid assembly 2. This is expected to improve the support stability of the hinge 3 at the mounting points 10 and 20.

[0082] (4) In (3) above, The fitting holes 45A and 45B are A pair of first side edges 451, 451 are spaced apart and arranged parallel to each other, It has a pair of second side edges 452, 452 that are spaced apart and arranged parallel to each other. The mating holes 55A and 55B are A pair of first side edges 551, 551 are spaced apart and arranged parallel to each other, It has a pair of second side edges 552, 552 that are spaced apart and arranged parallel to each other. The fitting hole 45A is provided with a pair of first side edges 451, 451 oriented along the axial direction of the pivot axis. The fitting hole 45B is provided with a pair of first side edges 451, 451 oriented along the radial direction of the pivot axis. The fitting holes 55A and 55B are provided with a pair of first side edges 451, 451 oriented along the radial direction of the pivot axis. The mating projections 15A and 15B are, A first rib 155 that fits onto the first side edge 451, It has a second rib 156 that fits onto the second side edge 452. The mating projections 25A and 25B are, A first rib 255 that fits onto the first side edge 551, It has a second rib 256 that fits onto the second side edge 552.

[0083] With this configuration, the axial and radial movement of the pivot axis X between the first bracket 4 and the console box 1, and the axial and radial movement of the pivot axis X between the second bracket 5 and the lid assembly 2 can be restricted by the fitting protrusions 15A, 15B and 25A, 25B that are fitted into the fitting holes 45A, 45B and 55A, 55B. This is expected to improve the support stability of the hinge 3 at the mounting portions 10 and 20 of the hinge 3.

[0084] (5) In (4) above, The mating projections 15A, 15B, and 25A, 25B are The number of first ribs 155 and 255 that fit onto the first side edge 451 and first side edge 551 is different from the number of second ribs 156 and 256 that fit onto the second side edge 452 and second side edge 552.

[0085] For example, when fasteners N such as screws or bolts are screwed into the bosses 13A and 14B on the console box 1 side, or the bosses 24A and 24B on the lid assembly 2 side, a rotational torque corresponding to the tightening direction of the fasteners N is applied to the first bracket 4 and the second bracket. This rotational torque acts in two directions: one that causes the mounting portion 10 on the console box 1 side and the first bracket 4 to rotate relative to each other, and another that causes the mounting portion 20 on the lid assembly 2 side and the second bracket 5 to rotate relative to each other. Therefore, by setting the number and arrangement of the first ribs 155 and 255 according to the direction in which the rotational torque acts, the relative rotation between the mounting portion 10 on the console box 1 side and the first bracket 4 can be restricted. Furthermore, by setting the number and arrangement of the second ribs 156 and 256, the relative rotation between the mounting portion 20 on the lid assembly 2 side and the second bracket 5 can be restricted. This is expected to improve the support stability of the hinge 3 at the mounting points 10 and 20 of the hinge 3.

[0086] (6) In (5) above, In the second bracket 5, the fitting holes 55A and 55B are located between the second insertion holes 54A and 54B in the axial direction of the pivot axis X. The fitting holes 55A and 55B are provided such that the first side edges 551, 551 are spaced apart in the axial direction of the pivot axis X. In one of the fitting holes 55A and 54B, fitting hole 55A, the number of first ribs 255 that fit onto the first side edge 551 is greater than the number of second ribs 256 that fit onto the second side edge 552. In the other fitting hole 55B, the number of first ribs 255 that fit into the first side edge 551 is less than the number of second ribs 256 that fit into the second side edge 552.

[0087] With this configuration, the relative axial and radial displacement of the pivot axis X between the mounting portion 20 of the lid assembly 2 and the second bracket 5 can be appropriately restricted by the fitting projection 25A that fits into the fitting hole 55A and the fitting projection 25B that fits into the fitting hole 55B. Furthermore, the fitting hole 55A and the second insertion hole 54A, and the fitting hole 55B and the second insertion hole 54B are provided with their positions offset in the axial direction of the pivot axis X. Therefore, when the fastener N, which has passed through the second insertion hole 54B, is screwed into the boss portion 24B on the lid assembly 2 side, a rotational torque acts on the fitting projection 25B fitted into the fitting hole 55B in the circumferential direction around the rotation center C24B of the boss portion 24B, in a direction that causes relative displacement with respect to the fitting hole 55B. For example, in Figure 16, when a rotational torque in the clockwise direction CW is applied, the second side edges 552, 552 of the fitting hole 55B are pressed against the second ribs 256, 256 of the fitting hole 55B. As described above, when rotational torque is applied, the number of second ribs 256, 256 that press against the second side edges 552, 552 of the fitting hole 55B is greater than the number of first ribs 255. Therefore, the pressing force corresponding to the applied rotational torque can be distributed and received by the two second ribs 256, 256. As a result, the resistance to pressing force is increased compared to the case where only one second rib 256 is provided, and the possibility of deformation of the second rib 256 due to the pressing force caused by tightening of the fastener N can be reduced. If deformation occurs in the second rib 256 or the first rib 255, looseness will occur in the fitting portion between the fitting projection 25B and the fitting hole 55B after the fastener N is tightened, due to the deformation of the first rib 255 or the second rib 256. By configuring it as described above, the possibility of looseness occurring in the fitting portion between the fitting projection 25B and the fitting hole 55B after the fastener N is tightened can be reduced.

[0088] (7) In (5) or (6) above, In the first bracket 4, the fitting holes 45A and 45B are positioned so as to overlap with the second insertion holes 44A and 44A when viewed from the radial direction of the pivot axis X. The fitting hole of the first bracket 4 is A fitting hole 45A (first fitting hole) is provided, in which the first side edges 451, 451 are arranged so as to be spaced apart in the radial direction of the pivot axis, The pair of first side edges are arranged in a manner that they are spaced apart in the axial direction of the pivot axis, and the fitting hole 45B (second fitting hole) is also provided. In the fitting hole 45A, the number of first ribs 155 that fit onto the first side edge 451 is greater than the number of second ribs 156 that fit onto the second side edge 452. In the fitting hole 45B, the number of first ribs 155 that fit onto the first side edge 451 is greater than the number of second ribs 156 that fit onto the second side edge 452.

[0089] With this configuration, the relative axial and radial displacement of the pivot axis X between the mounting portion 10 of the console box 1 and the first bracket 4 can be appropriately restricted by the fitting projection 15A that fits into the fitting hole 45A and the fitting projection 15B that fits into the fitting hole 45B.
