DETAILED DESCRIPTION OF THE INVENTION
Specific examples of the present invention will be described with reference to the accompanying drawings.
[0012]
In FIG. 1, the vehicle door handle includes a frame 12 attached to the inside of a vehicle door panel 11 so as to extend in the front-rear direction of the vehicle body (left-right direction in FIG. 1). Thus, a hand grip 20 is disposed outside the panel 11, and an L-shaped leg 21 is formed at one end (right end) of the hand grip 20. , Passes through an insertion hole (not shown), extends inside the panel 11, passes through a hole 12 </ b> B formed in one end (right end) of the frame 12, and can be tilted to a support part 14 provided in the frame 12. Inserted. A part of the leg portion 21 of the handgrip 20 is formed as a rotation center portion 22.
[0013]
An L-shaped arm portion 25 is formed at the other end portion of the handgrip 20, and this arm portion 25 passes through an insertion hole (not shown), extends inside the panel 11, and other than the frame 12. After passing through the hole 12 </ b> B formed at the end (left end), it is connected to the link mechanism 31 linked to the door lock mechanism 30. When the other end 24 of the handgrip 20 is raised in the outer direction of the panel 11 (upward in FIG. 1), the handgrip 20 rotates within a predetermined angular range around the rotation center portion 22. The door lock mechanism 30 is used to open the vehicle door.
[0014]
A restricting means 50 is provided between the arm portion 25 of the handgrip 20 and the frame 12, and this restricting means 50 is the extending direction of the frame 12 of the handgrip 20 (the insertion direction of the leg portion 21). The movement of the handgrip 20 is also permitted while preventing the shift in the vehicle longitudinal direction). 2 to 6, the restricting means 50 includes a pair of protrusions 51 and 51 that project from the inner edge of the hole 12A formed in the frame 12, and an arm portion of the handgrip 20. 25, and a pair of protrusions 51 and 51 are slidably fitted to each other and a pair of grooves 53 and 53. The base portion of each protrusion 51 is a boss 59.
[0015]
That is, as clearly shown in FIG. 6, grooves 53 are engraved on each surface of the arm portion 25 of the hand grip 20 along the extending direction. The groove 53 has an L-shape as a whole, and the terminal portion (lower lower portion in FIG. 6) of the groove 53 is opened to the right in FIG. 6, which coincides with the insertion direction of the leg portion 21 through the opening 52. . By forming such a groove 53, walls 54 and 55 are formed in the arm portion 25 so as to face each other in the longitudinal direction of the vehicle body (the insertion direction of the leg portion 21), and the end portion (lower end portion) of the wall 55. Is connected to a protrusion 56 formed integrally with the arm 25.
[0016]
When the hand grip 20 is rotated, the arm portion 25 of the hand grip 20 is guided by the pair of protrusions 51 and 51 on the frame 12 side in the pair of grooves 53 and 53. At this time, when the rotation amount reaches a predetermined value, the protrusion 56 that moves integrally with the handgrip 20 and moves to the outside of the panel (upward in FIG. 1) engages with the boss 59 to rotate the handgrip 20. Regulations are made. Further, when the handgrip 20 is shifted in the extending direction of the frame 12, that is, in the insertion direction of the leg portion 21 (the left-right direction in FIGS. 1 to 3), the pair of protrusions 51 and 51 on the frame 12 side are the walls 54 and 55. It is blocked by abutting. Thus, play of the handgrip 20 in the extending direction of the frame 12 is prevented.
[0017]
The door handle device described above is assembled in the following procedure. That is, first, the leg portion 21 formed at one end portion (right end portion) of the handgrip 20 is extended to the inside of the panel 11, and then the hole 12B formed at one end portion (right end portion) of the frame 12 is inserted. Insert it. At this time, the leg portion 21 formed at one end portion (right end portion) of the handgrip 20 does not completely enter the support portion 14 provided on the frame 12.
[0018]
Next, the leg 25 formed on the other end (right end) 24 of the handgrip 20 is inserted into the hole 12 </ b> A on the other end (left end) of the frame 12. Thereafter, when the hand grip 20 is shifted to the right in FIG. 1, which is the insertion direction of the leg portion 21, the leg portion 21 at one end portion (right end portion) of the hand grip 20 is completely fitted into the support portion 14 of the frame 12. Is done. At this time, the pair of protrusions 51 and 51 are slidably fitted into the pair of grooves 53 and 53 from the opening 52, respectively. That is, when the end portions (lower end portions) of the grooves 53 are aligned with the corresponding protrusions 51 and then the arm 25 is pushed into the frame 12, the grooves 53 slide along the corresponding protrusions 51. This sliding is completed when the base end portion (upper upper end portion in FIG. 6) of each groove 53 engages with the corresponding boss 59. That is, the leg portion 21 at one end portion (right end portion) of the hand grip 20 is supported in the support portion 14 so as to be tiltable around the rotation center portion 22. At this time, the protrusion 56 formed integrally with the lower end of the arm 25 faces the boss 59.
[0019]
Thus, when the handgrip 20 is rotated, the arm portion 25 of the handgrip 20 is guided by the pair of protrusions 51 and 51 on the frame 12 side in the pair of grooves 53 and 53, and the amount of rotation reaches a predetermined value. The protrusion 56 that moves integrally with the handgrip 20 and moves to the outside of the panel (upward in FIG. 1) engages with the boss 59 to prevent the handgrip 20 from coming off. Moreover, the movement of the handgrip 20 in the extending direction of the frame 12, that is, the insertion direction of the leg portion 21 (the left-right direction in FIGS. 1 to 3) is blocked by the pair of protrusions 51 and 51 on the frame 12 side. The backlash of the grip 20 in the extending direction of the frame 12 is prevented.
[0020]
