  FIG. 1 is a perspective view of the console box 1 of the first embodiment. The console box 1 is disposed, for example, between the driver's seat and the passenger's seat of the vehicle. The console box 1 includes a lid 12, a storage box 14 and a hinge device 10. The hinge device 10 rotatably supports the lid 12 with respect to the storage box 14.

  FIG. 1A shows a state before the hinge device 10 is attached, and FIG. 1B shows a state where the hinge device 10 is attached. The lid 12 is maintained in posture by the hinge device 10 at any rotational position between the fully open state and the fully closed state. The lid 12 and the storage box 14 function as mounting members for mounting the hinge device 10.

  The lid 12 is formed with a first shaft hole 16 into which the hinge device 10 can be inserted, and the storage box 14 is formed with a second shaft hole 18 into which the hinge device 10 can be inserted. The first shaft hole 16 has a first rotation stopping portion 16a recessed in the inner peripheral surface, and the second shaft hole 18 has a second rotation stopping portion 18a recessed in the inner peripheral surface. . The first axial hole 16 and the second axial hole 18 are coaxially arranged.

  The hinge device 10 includes a bearing 22 and a shaft 20 inserted into the bearing 22. The hinge device 10 is inserted into the first shaft hole 16 and the second shaft hole 18, the rotation of the bearing portion 22 is limited to the first shaft hole 16, and the rotation of the shaft portion 20 is restricted to the second shaft hole 18. . The rotation of the shaft portion 20 may be limited to the first shaft hole 16, and the rotation of the bearing portion 22 may be limited to the second shaft hole 18.

  The hinge device 10 is inserted into and attached to the first shaft hole 16 and the second shaft hole 18 in an assembled state in which the shaft portion 20 and the bearing portion 22 are integrally assembled. Thereby, the attachment operation to the console box 1 of the hinge apparatus 10 can be made easy. Before shipment of the hinge device 10, the rotational torque generated in the hinge device 10 can be confirmed.

  FIG. 2 is a perspective view of the shaft portion 20 of the hinge device 10. FIG. 3 is a side view of the shaft portion 20 of the hinge device 10. The shaft portion 20 has an insertion portion 30, a locking claw 32, an opposing surface 34, a radial projection 36, an elastic locking portion 38 and an engagement elastic portion 40.

  The insertion portion 30 is formed in a cylindrical shape, and is inserted into the bearing portion 22. The insertion portion 30 constitutes a part of a cylindrical shaft portion 20 main body. The locking claw 32 is located at the tip end in the direction of insertion into the bearing portion 22 and locks to the hole edge of the bearing portion 22. A plurality of locking claws 32 are formed by slits and can be bent.

  The opposing surface 34 extends perpendicularly from the outer peripheral surface of the insertion portion 30, that is, in the radial direction. The opposing surface 34 functions as a stopper that stops the insertion into the bearing portion 22.

  The radial protrusion 36 is formed to protrude on the outer peripheral surface of the shaft portion 20 and is fitted to the second rotation stopping portion 18 a of the second shaft hole 18. As a result, the shaft portion 20 does not rotate in the second shaft hole 18. The radial projection 36 extends along the axial direction and functions as a guide when the hinge device 10 is inserted into the first axial hole 16 and the second axial hole 18. The axial direction means a direction along the central axis of the shaft portion 20, and the radial direction means a direction perpendicular to the central axis of the shaft portion 20 and passing through the central axis. Further, the circumferential direction is a direction perpendicular to the central axis of the shaft portion 20 and along the circumference surrounding the central axis.

  The elastic locking portion 38 is radially bendable and is locked to the inner circumferential surface of the second shaft hole 18. As a result, the shaft portion 20 does not move in the axial direction in the second shaft hole 18, and the hinge device 10 is fixed to the storage box 14.

  As shown in FIG. 2, the engagement elastic portion 40 is formed in a band shape along the circumferential direction on the facing surface 34 and is formed so as to be flexible. The engagement elastic portion 40 gives the user who opens and closes the lid 12 a click feeling at a predetermined rotational position by engagement with the engagement convex portion of the bearing portion 22.

  As shown in FIG. 3A, a gap 43 in which the engaging elastic portion 40 can be bent toward the proximal end 20 a in the axial direction is formed closer to the proximal end 20 a than the engaging elastic portion 40. Further, as shown in FIG. 2, the engagement elastic portion 40 is located apart from the outer peripheral surface 20 b of the main body of the shaft portion 20, and has an air gap 41 between it and the outer peripheral surface 20 b. Thereby, the elastic force of the engagement elastic portion 40 is secured, and the click feeling is easily transmitted to the user. The engagement elastic portion 40 is formed on the outer peripheral side of the shaft portion 20 so as to be bent more easily than the main body of the shaft portion 20, and when bent, is displaced in the axial direction and circumferential direction compared with the opposing surface 34 of the rigid portion.

  As shown in FIG. 3A, the engagement elastic portion 40 has a recess 40a formed in the center and a pair of rising portions 40b formed to rise toward the center side recess 40a. . The rising portion 40 b protrudes toward the tip end side in the axial direction from the facing surface 34. The recess 40 a is bent from the rising portion 40 b and recessed toward the proximal end 20 a in the axial direction.

  FIG. 4 is a perspective view of the bearing 22. The bearing portion 22 is formed in a cylindrical shape and has an insertion hole 44 into which the shaft portion 20 is inserted. On the outer peripheral surface of the bearing portion 22, a radial protrusion 48 fitted to the first rotation stopping portion 16 a of the first shaft hole 16 is formed. The radial projection 48 extends in the axial direction and functions as a guide when the hinge device 10 is inserted into the first axial hole 16 and the second axial hole 18.

  A plurality of engagement projections 46 are formed on the annular bearing end surface 42 of the bearing portion 22. The bearing end surface 42 is located on the tip side in the direction of receiving the shaft portion 20, and faces the opposing surface 34 of the shaft portion 20 in an assembled state in which the shaft portion 20 is assembled. The engagement convex portion 46 protrudes in the axial direction and is engageable with the engagement elastic portion 40 of the shaft portion 20 in an assembled state.

  FIG. 5 is a perspective view of the hinge device 10. The hinge device 10 shown in FIG. 5A is rotated 90 degrees from the hinge device 10 shown in FIG. 5B. 6 is a sectional view taken along line AA of the hinge device 10 shown in FIG. 5 (b).

  In the hinge device 10, as shown in FIG. 6, the insertion portion 30 of the shaft portion 20 is inserted into the insertion hole 44 of the bearing portion 22, and the locking claw 32 of the shaft portion 20 is at the hole edge of the insertion hole 44 of the bearing portion 22. It locks and is assembled in one. The outer peripheral surface 30a of the insertion portion 30 is set to a diameter slightly larger than the inner peripheral surface 44a of the bearing portion 22, and is in pressure contact with the inner peripheral surface 44a. Thereby, it slides at the time of relative rotation of axial part 20 and bearing 22, and can output rotation torque by frictional force, and can maintain posture of lid 12. Further, since the outer peripheral surface 30a of the insertion portion 30 and the inner peripheral surface 44a of the bearing portion 22 are in surface contact over the entire periphery, it is possible to suppress stress concentration occurring in the sliding surface.

  As shown in FIG. 5A, in the assembled state, the bearing end surface 42 and the opposing surface 34 face each other at a predetermined interval. The distance between the bearing end surface 42 and the opposing surface 34 is larger than the protruding height of the engagement protrusion 46. The engagement convex portion 46 axially protrudes toward the facing surface 34 and approaches the facing surface 34. By providing the engagement convex portion 46 and the engagement elastic portion 40 on the bearing end surface 42 and the opposing surface 34, the engagement elastic portion 40 does not interfere with the assembly operation when assembling.

  FIG. 7 is a view for explaining the engagement operation of the engagement elastic portion 40 and the engagement convex portion 46. As shown in FIG. In the hinge device 10 shown in FIG. 7A, the engagement convex portion 46 and the engagement elastic portion 40 are in a rotational position shifted by 90 degrees, and for example, the lid 12 is closed. In this state, the engagement convex portion 46 is not in contact with the facing surface 34 and does not interfere with the shaft portion 20.

  When the lid 12 is opened, the shaft portion 20 and the bearing portion 22 rotate relative to each other according to the relative rotation of the lid 12 and the storage box 14. As shown in FIG. 7B, by the relative rotation of the shaft portion 20 and the bearing portion 22, the engagement convex portion 46 abuts on the rising portion 40b, and the engagement convex portion 46 tries to get over the rising portion 40b. The engagement elastic portion 40 bends against the engagement convex portion 46 and is displaced in the axial direction or circumferential direction on the basis of the opposing surface 34 by the bending.

  As shown in FIG. 7C, the rising portion 40b is bent so as to be pushed down in the axial direction on the basis of the opposing surface 34 by the contact with the engagement convex portion 46. Further, the top portions 40c of the pair of rising portions 40b are displaced so as to approach in the circumferential direction. That is, the rising portion 40 b swings with the root connected to the facing surface 34 as a rotation fulcrum, and is bent in the axial direction and the circumferential direction. When the top 40c of the rising portion 40b is displaced not only in the axial direction but also in the circumferential direction, the recess 40a is bent so as to be smaller in the circumferential direction, and the stress applied at the time of elastic deformation can be dispersed. If the engaging elastic portion 40 is bent only in the axial direction, the stress is concentrated at the root of the engaging elastic portion 40, but by bending in the circumferential direction as well, the stress at the time of elastic deformation becomes the engaging elastic It is dispersed at the root of the portion 40 and at the bottom of the recess 40a. Thereby, the durability of the engagement elastic portion 40 can be improved.

  As shown in FIG. 7 (d), when the engagement protrusion 46 advances to the center of the engagement elastic portion 40, it engages with the recess 40 a. The engagement elastic portion 40 engages with the engagement convex portion 46 at a predetermined rotational position. When the tip end of the engagement convex portion 46 enters the concave portion 40 a, the rising portion 40 b is restored so as to stand up and hit against the engagement convex portion 46, and a click feeling can be imparted to the user who opens the lid 12. The engaging elastic portion 40 can give the user a click feeling without using a separate spring. Further, by separately providing the configuration of the sliding surface of the insertion portion 30 and the insertion hole 44 for maintaining the posture of the lid 12 and the engagement convex portion 46 and the engagement elastic portion 40 which cause a click feeling, stress is provided. A configuration can be realized in which concentration is distributed.

  As shown in FIG. 7 (d), the engagement projection 46 slightly intrudes into the recess 40a. At this time, the bottom 40 d of the recess 40 a and the engagement protrusion 46 do not contact with each other. That is, the recess 40 a is recessed more than the engagement margin in the axial direction of the engagement protrusion 46 and the recess 40 a. The engagement margin in the axial direction of the engagement convex portion 46 and the concave portion 40 a is an axial length in which the engagement convex portion 46 enters the concave portion 40 a in the engaged state. Thus, it is possible to secure an axial length of the recessed portion 40a and realize an operation of bending so that the top portions 40c of the pair of rising portions 40b approach in the circumferential direction.

  The axial length of the recess 40 a, that is, the recess amount of the recess 40 a may be longer than the protruding height of the engagement protrusion 46. Thereby, the axial direction length of crevice 40a is securable enough.

  Since both ends of the engagement elastic portion 40 are smoothly continued along the opposing surface 34, the engagement convex portion 46 is smooth to the engagement elastic portion 40 regardless of the direction of relative rotation of the shaft portion 20 and the bearing portion 22. Contact

  FIG. 8 is a view for explaining a bearing portion of a modified example. The bearing 122 shown in FIG. 8A is different from the bearing 22 shown in FIG. The bearing portion 122 of the modified example has a first engagement convex portion 46 a and a second engagement convex portion 46 b on the bearing end surface 42. The first engagement convex portions 46a are provided in a pair at a 180 degree offset, and the second engagement convex portions 46b are provided in a 180 degree offset. The first engagement convex portion 46 a and the second engagement convex portion 46 b are arranged at equal intervals.

  The first engagement convex portion 46 a and the second engagement convex portion 46 b can be engaged with the engagement elastic portion 40 of the shaft portion 20 by relative rotation of the shaft portion 20 and the bearing portion 122. The protrusion height of the first engagement convex portion 46 a is higher than the protrusion height of the second engagement convex portion 46 b, and a different click feeling can be transmitted to the user.

  The bearing 222 shown in FIG. 8B is different from the bearing 22 shown in FIG. 4 in the number and the size of the engagement protrusions 46. The first engagement convex portion 46 c is provided in a pair at a position shifted by 180 degrees, and a plurality of second engagement convex portions 46 d are provided between the pair of first engagement convex portions 46 c. The first engagement convex portion 46 c and the second engagement convex portion 46 d can be engaged with the engagement elastic portion 40 of the shaft portion 20 by relative rotation of the shaft portion 20 and the bearing portion 222. Every time the first engagement convex portion 46 c and the second engagement convex portion 46 d engage with the engagement elastic portion 40, the click feeling can be transmitted to the user.

  FIG. 9 is a view for explaining the shaft portion of the modified example. The shaft portion 120 shown in FIG. 9A has a different shape of the engagement elastic portion 140 than the shaft portion 20 shown in FIG. 3A. The engagement elastic portion 140 of the modified example is not a double-ended piece like the engagement elastic portion 40, but a cantilevered piece. One end of the belt-like engaging elastic portion 140 is separated from the facing surface 34.

  The engagement elastic portion 240 shown in FIG. 9B is formed so as to axially project from the second opposing surface 34b which is recessed from the first opposing surface 34a, and is flexible in the circumferential direction. A recess 240 a is formed at the tip of the engagement elastic portion 240, and engages with the engagement protrusion 46 of the bearing 22. The engagement elastic portion 240 swings against the engagement convex portion 46, and the concave portion 240a is displaced in the axial direction and the circumferential direction.

  The shaft portion 320 shown in FIG. 9C has an engagement elastic portion 340 which is formed in a substantially M shape extending from the second opposing surface 34b which is recessed from the first opposing surface 34a. The engagement elastic portion 340 is formed between a pair of standing portions 340c standing from the second opposing surface 34b, a pair of rising portions 340b bent from the tip of the standing portion 340c, and a pair of rising portions 340b. And a recessed portion 340a. By providing the erected portion 340c, the engaging elastic portion 340 can be easily bent in the circumferential direction and the axial direction, as compared with the engaging elastic portion 40 shown in FIG. 3A.

  FIG. 10 is a perspective view of the hinge device 400 of the second embodiment. 11 (a) is a left side view of the hinge device 400, FIG. 11 (b) is a front view of the hinge device 400, and FIG. 11 (c) is a right side view of the hinge device 400. is there. 12 (a) is a bottom view of the hinge device 400, FIG. 12 (b) is a rear view of the hinge device 400, and FIG. 12 (c) is a plan view of the hinge device 400.

  The hinge device 400 includes a shaft 420 and a bearing 422. The shaft portion 420 is integrally connected with the bearing portion 422, and can rotate relative to the bearing portion 422. The shaft 420 has an insertion portion (not shown) inserted into the bearing 422, a locking claw 432, a first radial projection 436, an elastic locking portion 438, a proximal end cylindrical portion 54, and a first abutment rib. 50 and a flange portion 62.

  The locking claws 432 are located at the tip end in the insertion direction to the bearing portion 422, project radially outward, and are formed so as to be radially bendable. The locking claws 432 are caught on the hole edge of the bearing portion 422 to prevent the shaft portion 420 from coming off the bearing portion 422.

  The proximal end cylindrical portion 54 is located on the proximal end 420 a side of the shaft portion 420, is located outside the bearing portion 422, is not inserted into the bearing portion 422, and is larger than the insertion portion inserted into the bearing portion 422. It is a diameter. The proximal end 420 a of the proximal end cylindrical portion 54 is formed with a flange portion 62 projecting radially outward.

  The first radial protrusion 436 is formed so as to protrude from the outer peripheral surface of the proximal end cylindrical portion 54, and is fitted to the second rotation stopping portion 18 a of the second shaft hole 18. The first radial projection 436 extends in the axial direction, and functions as a guide when the hinge device 400 is inserted into the first axial hole 16 and the second axial hole 18. A first protrusion 436 a is formed on the side surface of the first radial protrusion 436 so as to protrude in the circumferential direction.

  The first abutment rib 50 is formed in a rib shape on the outer peripheral surface of the proximal end cylindrical portion 54 and abuts on the inner peripheral surface of the second shaft hole 18 in the mounted state. The amount of protrusion of the first abutment rib 50 is smaller than that of the first radial protrusion 436, and a plurality of the first abutment ribs 50 are circumferentially separated. The first abutment rib 50 extends along the axial direction, and extends over half or more of the axial length of the proximal cylindrical portion 54. The elastic locking portion 438 is radially flexible and locks to the inner surface of the second axial hole 18. As a result, the shaft 420 does not move in the axial direction in the second shaft hole 18, and the hinge device 400 is fixed to the storage box 14.

  The bearing portion 422 is formed in a cylindrical shape. The bearing portion 422 has an insertion hole 444, a second radial projection 448, a second abutment rib 52 and a projection 60. The shaft 420 is inserted into the insertion hole 444. The second radial protrusion 448 is formed so as to protrude in the radial direction on the outer peripheral surface of the bearing portion 422, and is fitted to the first rotation stopping portion 16 a of the first shaft hole 16. The second radial projection 448 extends in the axial direction and functions as a guide when the hinge device 400 is inserted into the first axial hole 16 and the second axial hole 18. A second protrusion 448 a is formed on the side surface of the second radial protrusion 448 so as to protrude in the circumferential direction.

  The second abutment rib 52 is formed to protrude on the outer peripheral surface of the bearing portion 422 and extends in the axial direction. A plurality of second abutment ribs 52 are circumferentially spaced apart and formed to extend over half the axial length of the bearing portion 422.

  The hinge device 400 is inserted into the first shaft hole 16 and the second shaft hole 18 with the locking claw 432 as the insertion direction end. As shown in FIG. 11C, the circumferential width D2 of the second radial projection 448 located on the front end side in the insertion direction is the circumference of the first radial projection 436 located on the rear end side in the insertion direction. It is smaller than the direction width D1. By reducing the size of the second radial projection 448 positioned on the front end side in the insertion direction, it becomes easy to insert the first axial hole 16 and the second axial hole 18.

  As shown in FIG. 11 (b), the second radial projection 448 is positioned apart from the rear end 422 a of the bearing portion 422 by a predetermined axial length L 1. Thereby, a gap of length L1 or more can be provided between the first radial protrusion 436 and the second radial protrusion 448, and the axial length of the first shaft hole 16 and the second shaft hole 18 can be reduced. It can respond to the error.

  As shown in FIG. 12C, the outer diameter R2 of the bearing portion 422 is different from the outer diameter R1 of the proximal end cylindrical portion 54, and is smaller than the outer diameter R1 of the proximal end cylindrical portion 54. By making the outer diameter R2 of the bearing portion 422 positioned on the front end side in the insertion direction smaller than the proximal end side cylindrical portion 54 on the rear end side, insertion into the first shaft hole 16 and the second shaft hole 18 can be facilitated.

  The rear end 422 a of the bearing 422 is formed with a projection 60 projecting toward the base end side cylindrical portion 54. The protrusion 60 can be in contact with the distal end of the proximal end cylindrical portion 54. By forming the projecting portion 60, the surface on the tip end side of the proximal end side cylindrical portion 54 and the surface on the rear end side of the bearing portion 422 are in surface contact, and the relative rotation of the shaft portion 420 and the bearing portion 422 becomes difficult. You can suppress that.

  FIG. 13 is a cross-sectional view of the hinge device 400 in the attached state. The insertion portion 430 of the shaft portion 420 is inserted into the bearing portion 422. By inserting the insertion portion 430 into the bearing portion 422, the shaft portion 420 and the bearing portion 422 can be integrated, and the assembly of the hinge device 400 is easy. The inner circumferential surface of the bearing portion 422 and the outer circumferential surface of the insertion portion 430 are in surface contact, and slide when the bearing portion 422 and the shaft portion 420 rotate relative to each other. The posture of the lid 12 can be maintained by the rotational torque generated by this friction.

  The axial portion 420 is formed with a through hole 56 penetrating in the axial direction. By forming the through holes 56 in the shaft portion 420, it is possible to suppress the deformation of the insertion portion 430 at the time of molding, and to suppress the decrease in the roundness of the insertion portion 430. Thereby, the outer peripheral surface of the insertion portion 430 can be configured to be in surface contact with the inner peripheral surface of the bearing portion 422 stably.

  The hinge device 400 is attached to the first shaft hole 16 and the second shaft hole 18, the outer peripheral surface of the bearing portion 422 is opposed to the inner peripheral surface of the first shaft hole 16, and the inner periphery of the second shaft hole 18 The outer peripheral surface of the proximal end cylindrical portion 54 faces the surface. The hinge device 400 is inserted and attached to the first shaft hole 16 and the second shaft hole 18 from the locking claw 432 located at the tip in the insertion direction in the integrated state in which the insertion portion 430 is inserted into the bearing portion 422 . Thus, the hinge device 400 can be easily attached simply by inserting it into the first axial hole 16 and the second axial hole 18.

  The inner diameter of the first axial hole 16 is smaller than the inner diameter of the second axial hole 18. Since the outer diameter of the bearing portion 422 is smaller than the outer diameter of the proximal end cylindrical portion 54, when the bearing portion 422 is press-fit into the first shaft hole 16 and the proximal end cylindrical portion 54 is press-fit into the second shaft hole 18 Can be inserted easily. By press-fitting the bearing portion 422 and the proximal end side cylindrical portion 54 into the first shaft hole 16 and the second shaft hole 18, it is possible to suppress the deviation between the rotation of the hinge device 10 and the rotation of the lid 12.

  The tip end portion 422 b of the bearing portion 422 is bent so as to protrude radially inward. As a result, even if the locking claws 432 are smaller than the insertion portions 430 in the radial direction, they are easily caught by the bearing portions 422. By positioning the locking claws 432 radially inward of the outer diameter of the insertion portion 430, the insertion portion 430 can be easily formed, and a decrease in the roundness of the insertion portion 430 can be suppressed.

  Fig.14 (a) is line AA sectional drawing of the hinge apparatus 400 shown in FIG. 13, FIG.14 (b) is line BB sectional drawing of the hinge apparatus 400 shown in FIG.

  As shown in FIG. 14A, the first abutment rib 50 abuts on the inner circumferential surface of the second shaft hole 18. As shown in FIG. Thereby, rattling between the proximal end side cylindrical portion 54 and the second shaft hole 18 can be suppressed. Further, deformation of the bearing portion 422 can be suppressed by press-fitting the proximal end side cylindrical portion 54 so that the first contact rib 50 is crushed.

  The erroneous assembly preventing projection 58 is positioned 90 degrees away from the first radial projection 436, and the circumferential width is smaller than that of the first radial projection 436. By providing the erroneous assembly preventing projection 58, the elastic locking portion 438 can be reliably locked.

  The first radial projection 436 engages with a second rotation stopping portion 18 a formed in a groove shape in the second axial hole 18. This restricts the rotation of the shaft 420 relative to the second shaft hole 18.

  The first convex portions 436a formed on both side surfaces of the first radial projection 436 are in contact with both side surfaces of the second rotation stopping portion 18a. As a result, the first radial projection 436 can be easily press-fit into the second rotation stopping portion 18 a, and rattling of the shaft portion 420 in the circumferential direction with respect to the second shaft hole 18 can be suppressed.

  As shown in FIG. 14 (b), the second abutment rib 52 abuts on the inner circumferential surface of the first shaft hole 16. Thereby, rattling between the bearing portion 422 and the first shaft hole 16 can be suppressed. Further, since the second contact rib 52 is pressed into the first shaft hole 16 so as to be crushed, the deformation of the inner peripheral surface of the bearing portion 422 can be suppressed, and the sliding with the insertion portion 430 can be stabilized.

  The second radial projection 448 engages with a first rotation stopping portion 16 a formed in a groove shape in the first axial hole 16. Thereby, the bearing portion 422 is restricted from rotating with respect to the first shaft hole 16.

  The second protrusions 448a formed on both sides of the second radial projection 448 are in contact with both sides of the first rotation prevention portion 16a. As a result, the second radial projection 448 can be easily press-fit into the first rotation stopping portion 16a, and rattling of the bearing portion 422 in the circumferential direction with respect to the first shaft hole 16 can be suppressed. When the user opens the lid 12 and releases the lid 12, the lid 12 can be prevented from rotating.

  When inserting the hinge device 400 into the first axial hole 16 and the second axial hole 18, the circumferential positions of the first radial protrusion 436 and the second radial protrusion 448 are aligned and inserted. At this time, circumferential positions of the first rotation stopper 16a and the second rotation stopper 18a are also aligned. The circumferential width of the first rotation stopping portion 16a is smaller than the circumferential width of the second rotation stopping portion 18a. Thereby, the second radial projection 448 on the tip end side in the insertion direction can be moved to the first rotation stopper 16a through the second rotation stopper 18a. Since the circumferential width of the second radial projection 448 is smaller than that of the first radial projection 436, the second projection 448a can be prevented from colliding against the second rotation stopper 18a.

  FIG. 15 is a perspective view of the hinge device 500 of the third embodiment. FIG. 16 is a cross-sectional view of the hinge device 500. As compared with the hinge device 400 of the second embodiment shown in FIG. 10, in the hinge device 500 of the third embodiment, the proximal end cylindrical portion 554 of the shaft portion 520 is positioned on the tip end side in the insertion direction into the shaft hole. The difference is that the bearing 522 is located on the rear end side in the insertion direction.

  The shaft portion 520 includes an insertion portion 530, a locking claw 532, a proximal end cylindrical portion 554, a first radial protrusion 536, and an elastic locking portion 538. The bearing 522 includes a second radial protrusion 548, a second abutment rib 552, a protrusion 560 and a flange 562.

  The insertion portion 530 is inserted into the bearing portion 522. The locking claw 532 is positioned at the end in the insertion direction into the bearing 522, and is caught on the hole edge of the bearing 522 to prevent the shaft 520 from coming off the bearing 522, and integrally integrates the shaft 520 and the bearing 522 Make it A first abutment rib 550 is formed projecting on the outer peripheral surface of the proximal end cylindrical portion 554, and a second abutment rib 552 is formed projecting on the outer peripheral surface of the bearing portion 522.

  The hinge device 500 is inserted into and attached to the first shaft hole 16 and the second shaft hole 18 from the proximal end side cylindrical portion 554 positioned at the distal end in the insertion direction. In the hinge device 500, in the mounted state, the proximal end cylindrical portion 554 is positioned inside the first shaft hole 16, and the bearing portion 522 is positioned inside the second shaft hole 18. The first radial projection 536 engages with the first rotation stop portion 16 a of the first axial hole 16, and the second radial projection 548 engages with the second rotation stop portion 18 a of the second axial hole 18.

  Since the proximal end cylindrical portion 554 is located at the distal end in the insertion direction, the outer diameter of the proximal end cylindrical portion 554 is smaller than the outer diameter of the bearing portion 522. That is, among the outer diameters of the proximal end cylindrical portion and the bearing portion, one outer diameter located on the tip end side in the insertion direction is smaller than the other outer diameter. When the hinge device 500 is press-fit into the first shaft hole 16 and the second shaft hole 18, it becomes easy to press-in by reducing the outer diameter on the tip end side in the insertion direction.

  The circumferential width of the first radial protrusion 536 is smaller than the circumferential width of the second radial protrusion 548. That is, of the first radial protrusion and the second radial protrusion, the circumferential width of one radial protrusion located on the tip end side in the insertion direction is smaller than the circumferential width of the other radial protrusion . Thereby, the first radial projection 536 and the second radial projection 548 can be easily inserted into the first axial hole 16 and the second axial hole 18.
