That is, since the amount of movement of the handle 10 in the front and back direction is small in the vicinity of the shaft 13 of the handle 10, if the buffer member 25 is disposed in the vicinity of the shaft 13, the handle 10 is rotated to the door opening position. Even if it is a case, possibility that the buffer member 25 will be exposed to the side door surface side (vehicle inside) will become a very small thing.

Note that the configuration of the door handle device according to the present invention is not limited to the above-described configuration, and may be appropriately changed. For example, like the handle 10 according to the door handle device H2 shown in FIG. 4 (c), the contact surface 12a ′ of the buffer member 25 may be curved . In this case, since there is no acute angle portion in the arm portion 12, it is possible to suppress the deterioration / damage of the buffer member 25.

As shown in FIGS. 5A to 5C, the door handle device H3 according to another embodiment of the present invention is provided with the auxiliary buffer member 26 along the surface of the inner panel D1 constituting the side door D. It is what. The sub buffer member 26 may be disposed on the base portion 22.

  The auxiliary buffer member 26 is made of a material harder than the buffer member 25 described above, and contacts the second contact surface 12c of the handle 10 when the handle 10 is in the initial position, as shown in FIG. Further, the secondary buffer member 26 is disposed so as to contact the second contact surface 12c when the buffer member 25 contacts and deforms the contact surface 12a of the handle 10. That is, when the handle 10 (see FIG. 5A) rotated to the door opening position returns to the initial position, the contact surface 12a first contacts the buffer member 25 (see FIG. 5B). Then, the second contact surface 12c comes into contact with the auxiliary buffer member 26 (see FIG. 5C).

  In this way, the occurrence of a hitting sound is suppressed by the buffer member 25, and the handle 10 is stably held by the auxiliary buffer member 26 that is harder than the buffer member 25.

  In addition, the structure of the handle | steering-wheel 10 and the casing 20 is not limited to what was shown in figure, It does not interfere at all if it changes suitably according to a vehicle model etc. Further, in each of the above-described embodiments, the door handle device mounted on the inner side of the side door of the automobile is illustrated, but the present invention is not limited to this, and is mounted on a door of a building or the like, or other opening / closing body.
