  An inside door handle device for a vehicle as an embodiment of the present invention will be described in detail with reference to the drawings.

  1 is an exploded perspective view of the inside door handle device of the present embodiment, FIG. 2 is a cross-sectional view of the inside door handle device of the present embodiment along the longitudinal center line, and FIG. 3 is a first view of FIG. FIG. 4 is a side view of this embodiment, FIG. 5 is a front view of the handle base, and FIGS. 6A and 6B are views of the third locking portion. FIGS. 7A and 7B are enlarged views of main parts showing a state in which the engagement of the third locking part in FIG. 6 is released.

  The inside door handle device for a vehicle of this embodiment is disposed on the inner surface side of the door of the vehicle, and opens and closes the door when operated by an occupant. The inside door handle apparatus 1 is rotatably supported on the operation member storage portion 21 of the handle base 11 by a handle base 11 fixed to a door panel (not shown) and a door trim (not shown), and a support shaft 33a as an operation member 12. In addition, the operation handle 31 that is biased and held on the handle base 11 side by the winding spring 34, and further, the operation member 12 is rotatably supported by the operation member storage portion 21 by the support shaft 33b, and the door lock is locked / The lock knob 32 that performs unlocking and the escutcheon 13 that is disposed on the front side of the handle base 11 and hides the gap between the handle base 11 and the door trim are configured.

  Note that one end of a lock wire (not shown) is fixed to the distal end of the operation handle 31 on the base end side, and the operation handle 31 is operated to engage and release the door lock connected to the lock wire. Is called.

  In the outer peripheral surface 22 of the handle base 11, a first locking portion 23 and a second locking that restrict movement in the direction along the longitudinal direction as a locking portion are provided at a portion orthogonal to the longitudinal direction as one direction. A portion 24 is provided. Moreover, the 3rd latching | locking part 25 which regulates the movement of the direction orthogonal to a longitudinal direction as a latching | locking part is provided in the site | part along the longitudinal direction of the outer peripheral surface 22. As shown in FIG.

  The first locking portion 23 is formed of a flexible material, and is provided on the outer peripheral surface of the distal end portion of the beam portion 26 that extends from the back side to the front side of the handle base 11. In addition, the first locking portion 23 is formed with a slope 27a so as to increase from the front side to the back side of the handle base 11, and the locking surface 28a formed on the back side of the slope 27a The engaging portion 41 is locked and the escutcheon 13 is fixed to the handle base 11.

  The second locking portion 24 is provided at a portion facing and parallel to the portion of the outer peripheral surface 22 where the first locking portion is disposed. Similarly to the first locking portion 23, the second locking portion 24 is formed with a slope 27b so as to become higher from the front side to the back side of the handle base 11, and is formed on the back side of the slope 27b. The engaging portion 41 of the escutcheon 13 is locked to the locking surface 28 b to be fixed, and the escutcheon 13 is fixed to the handle base 11.

  A total of four third locking portions 25 are provided, two at each of two locations located in parallel along the longitudinal direction in the outer peripheral surface 22. The third locking portion 25 is formed with a slope 29 so as to become higher from the first locking portion 23 side toward the second locking portion 24 side, that is, obliquely intersecting the longitudinal direction. The engaging portion 41 of the escutcheon 13 is locked to the locking surface 30 formed behind the slope 29.

  The escutcheon 13 has an oval ring shape, and is disposed on the back side of the escutcheon 13 corresponding to each of the locking portions 23, 24, 25 disposed on the outer peripheral surface 22 of the handle base 11. The portion 41 is locked and fixed to the handle base 11. The engaging portion 41 has a square frame shape, and is provided at six locations corresponding to the locking portions 23, 24, and 25 of the handle base 11. Further, the escutcheon 13 is formed with an overhanging portion 42 in the periphery of the engaging portion 41 and overhanging the handle base 11 toward the operation member storage portion 21.

  Next, a method for attaching and detaching the escutcheon 13 to the handle base 11 will be described. In order to assemble the escutcheon 13 to the handle base 11, the engaging portions 41 of the escutcheon 13 are locked to the locking portions 23, 24, 25 corresponding to the engaging portions 41 from the front side of the handle base 11. Thus, the handle base 11 is assembled.

  In order to remove the escutcheon 13 assembled to the handle base 11, the lock knob 32 and the overhanging portion 42 of the escutcheon 13 are operated by operating the lock knob 32 as an operation member accommodated in the operation member accommodating portion 21 of the handle base 11. A tool is inserted into the gap S formed therebetween, the first locking portion 23 is operated, and the engagement between the first locking portion 23 and the engaging portion 41 is released.

  Then, in a state where the engagement between the first locking portion 23 and the engaging portion 41 is released, the escutcheon 13 is extended along the longitudinal direction from the first locking portion 23 side toward the second locking portion 24 side. And slide. When the escutcheon 13 is slid, the engaging portion 41 of the escutcheon 13 slides on the slope 29 of the third locking portion 25 to be disengaged from the second locking portion 24. The engagement with the engagement portion 41 is released, the engagement between the escutcheon 13 and the handle base 11 is all released, and the escutcheon 13 is removed.

  In particular, when the tool is locked to the first locking portion 23 and released, the tool tilts counterclockwise in FIG. 3 and pushes the overhanging portion 42, so that the second engagement is performed in a series of operations. The engagement between the stop portion 24 and the engagement portion 41 can be released.

  With the above configuration, since the periphery of the engaging portion 41 of the escutcheon 13 is projected to the operation member storage portion 21 side of the handle base 11, the engaging portion can be confirmed by looking into the escutcheon 13. The appearance can be improved and the merchantability can be enhanced without impairing the attachment / detachment workability.

  A tool is inserted into a gap formed between the operation member 12 and the escutcheon 13 by operating the operation member 12 accommodated in the operation member accommodating portion 21, and the engagement between the locking portion 23 and the engagement portion 41 is engaged. By releasing, it is possible to secure a sufficient work space, further improve the appearance without sacrificing the attachment / detachment workability, and further enhance the merchantability.
