  • Patent number: 11788324
    Abstract: An outer handle device for a vehicle door includes: an outer handle having a supported portion on one end part thereof in a longitudinal direction; a support member having paired leg portions sandwiching the supported portion from opposite sides; and a base having paired support side walls sandwiching the leg portions from opposite sides. The supported portion is pivotably supported on the support member attached to the base by the leg portion engaging with the support side wall. A restriction device is provided between the supported portion and the support member, the restriction device restricting displacement of the support member toward a side on which engagement of the support member with the base is released at least when pulling the outer handle. Accordingly, it is possible to maintain a state in which the support member is attached to the base, even when the outer handle is forcibly pulled.

  • Patent number: 11255113
    Abstract: An outer handle device for a vehicle door includes: a base mounted on an outer panel from an inside of the outer panel; an operating handle disposed on an outside of the outer panel and having a support shaft that extends along a swing axis on a support arm part entering the inside of the outer panel from the outside thereof; and a support member that is fitted to the base, engages with the support shaft from a rear, makes a front end of the support arm part abut against an abutment receiving part while the operating handle is swinging, and restrains displacement of the support shaft toward the outer panel. The base is provided with a restricting part that makes contact with the support arm part when the operating handle swings, thus restricting displacement of the operating handle in moving away inwardly from the outer panel.

  • Patent number: 10774568
    Abstract: In an outer handle device for a vehicle door, a cylinder lock having a key hole is mounted on an handle base in an attitude in which the cylinder lock is inclined downward or upward in going outward in a vehicle width direction while the key hole is made to face an outside when an operating handle is in an operated position but the key hole is covered by an handle main body when the operating handle is in a non-operated position. A provisional holding device is provided between the handle base and the cylinder lock, provisionally holds a mounted position and a mounted attitude of the cylinder lock with respect to the handle base, and is formed to guide the cylinder lock inserted into an insertion hole provided in the handle base so that the cylinder lock attains the mounted attitude at the mounted position.
