Since it is composed of a bolt 57 that has an enlarged diameter head portion 57a sandwiched therebetween and is screwed coaxially with the support shaft 44, a reinforcing plate 59 is interposed between the first mounting portion 42 and the outer panel 13. Thus, the force applied to the outer panel 13 when the handle 15 is operated can be dispersed, and deformation of the outer panel 13 can be prevented. Further, since the end of the support shaft 44 opposite to the base member 14 is supported by the outer panel 13 via the reinforcing plate 59, the support structure of the support shaft 44 becomes a double-support structure, and the lever member 40 rotates. The support shaft 44 can be strong enough to withstand the force applied to the support shaft 44 sometimes.

  Further, since the support shaft 44, which is a separate body from the base member 14 made of synthetic resin, is fixed to the support plate 47 attached to the base member 14, the support shaft having a relatively large diameter for supporting the lever member 40. By forming 44 integrally with the base member 14, there is no need to consider sink marks and the like generated on the surface of the base member 14, and the appearance molding of the base member 14 becomes easy.

  In addition, in this embodiment, the support member 48, the support plate 47, the support shaft 44, the lever member 40, and the return spring 60 can be assembled in advance as a lever member assembly unit 61, and the lever member assembly unit 61 is used as a base. By assembling to the member 14, the assembling workability is improved.

  Further, the lever member 40 is provided with a contact surface 69 that contacts the lever portion 16b of the first handle arm 16 so as to rotate in response to the rotation of the handle 15, and a rotation position for operating the latch device in an unlatched state. When the lever member 40 is rotated, the contact portion of the lever portion 16b with the contact surface 69 includes the axis C of the support shaft 44 and a plane PL substantially parallel to the rotation axis of the first handle arm 16. Therefore, the size of the contact surface 69 required to always contact the lever portion 16b of the rotating first handle arm 16 can be set small, thereby reducing the size of the door handle device. Can be achieved.

  That is, the contact portion of the lever portion 16b with the contact surface 69 includes the axis C of the support shaft 44 when the lever member 40 is rotated to the rotation position for operating the latch device in the unlatched state. The size D1 required for the contact surface 69 to contact the lever portion 16b at all times when set so as to exist on the plane PL substantially parallel to the 16 rotation axes is shown in FIG. When the lever member 40 is pivoted to the pivot position where the latch device is operated in the unlatched state, the contact portion of the lever portion 16b is offset from the plane PL. When the lever member 40 is in the position, when the rotation angle α of the lever member 40 is constant, the size D2 required for the contact surface 69 to make the lever portion 16b always contact is shown in FIG. As shown in The contact portion of the lever portion 16b to the abutment surface 69 becomes a support shaft when the lever member 40 is rotated to a rotation position for operating the latch device in an unlatched state. By setting so as to exist on a plane PL substantially including the axis C of 44 and being substantially parallel to the rotation axis of the first handle arm 16, the contact surface 69 required to always contact the lever portion 16b. The size can be set small.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. Is possible.

  For example, in the above embodiment, the case where the first and second handle arms 16 and 17 are connected to the handle 15 and the counterweight 30 is attached to the first handle arm 16 has been described.
