The link arm portion 4 b inserted on the inner surface side of the door panel 2 is engaged with the bell crank 9. When the handle body 4 is operated from the door closed position to the door open position, this handle operation is transmitted to a door lock mechanism (not shown) via the bell crank 9 or the like.

  The escutcheon 5 is formed of a synthetic resin material, and has a metal plating on the surface. The escutcheon 5 is usually formed of the same material as that of the handle body 4 in consideration of appearance. The escutcheon 5 is fixed to the base member 3 with bolts 20 on the inner surface side of the door panel 2. The escutcheon 5 protrudes outward from the second hole 2c of the door panel 2 at a position close to the end surface 4c on the other end side of the handle body 4. A member accommodating chamber 5a is formed in the protruding portion. The side of the member housing chamber 5a facing the handle body 4 is opened by the opening 5b. Further, a retaining hole 5d is formed in the bottom wall 5c of the member accommodating chamber 5a.

  As shown in detail in FIGS. 6 to 8, the gasket-integrated cap 10 is integrally formed from a backlash preventing portion 11 and a second gasket 12 connected thereto. The gasket integrated cap is formed of a material having a small frictional resistance with the handle main body 4, and unlike the escutcheon 5, the surface is not subjected to metal plating.

  The backlash preventing portion 11 is disposed in the member accommodating chamber 5 a of the escutcheon 5. The backlash preventing portion 11 is provided with a retaining protrusion 11a on the bottom side. When the retaining protrusion 11a is inserted into the retaining hole 5d, the backlash preventing portion 11 is mounted so as not to fall out of the member accommodating chamber 5a.

  Next, the operation of the door handle device 1 assembled in this way will be described. An operator rotates the handle body 4 from the door closed position to the door open position, or from the door open position to the door closed position. Then, the end surface 4c on the other end side of the handle body 4 moves along a rotation trajectory centering on the rotation center of the support arm portion 4a, and the backlash preventing portion 11 slides on the other end surface 4c that moves. . Therefore, the backlash of the handle body 4 can be effectively prevented at all rotational positions of the handle body 4. As a result, it is possible to reliably prevent problems such as generation of abnormal noise due to rattling.

  Since the gasket integrated cap 10 is a separate member from the escutcheon 5, it is not necessary to apply metal plating to the surface like the escutcheon 5, and the friction with the handle body 4 is as small as possible. Therefore, the generation of abnormal noise can be prevented without using grease. From the above, there is no generation of abnormal noise due to grease breakage or peeling of the metal plating, and generation of abnormal noise can be reliably prevented over a long period of time.

  In this embodiment, the gasket integrated cap 10 has a pair of handle side gasket pieces 12b extending along the longitudinal outer edge of the link arm portion 4b of the handle body 4, and the tips of the pair of handle side gasket pieces 12b.

Each handle-side gasket piece 12b can be assembled to the periphery of the second hole 2c by engaging with the periphery of the hole 2c. That is, since the escutcheon 5 fitted with the gasket integrated cap 10 can be fixed from the outer surface side of the door panel 2 after the handle body 4 is temporarily attached to the base member 3, the handle body 4 can be attached to the handle body 4 in the same manner as before. On the other hand, the escutcheon 5 can be assembled at an optimum position.

  In this embodiment, the backlash preventing portion 11 is housed in the member housing chamber 5a of the escutcheon 5, and the backlash preventing portion 11 is provided with a retaining projection 11a, and the escutcheon 5 is provided with a retaining hole 5d. ing. Accordingly, when the backlash preventing portion 11 is inserted into the member accommodating chamber 5a of the escutcheon 5, the gasket integrated cap 10 is mounted on the escutcheon 5, so that the gasket integrated cap 10 and the escutcheon 5 can be handled as a single component. The assembly work of the gasket integrated cap 10 and the escutcheon 5 can be facilitated. It should be noted that, contrary to this embodiment, it is of course possible to provide a retaining hole in the backlash preventing portion 11 and a retaining projection on the escutcheon 5.
