  • Patent number: 8528949
    Abstract: A door handle stroke change structure includes a latch mechanism, an electric latch drive mechanism, a mechanical latch drive mechanism, and an operation member which operates the electric latch drive mechanism and the mechanical latch drive mechanism. The operation member is moveable among a closed position, a first position at which the electric latch drive mechanism is operated, and a second position at which the mechanical latch drive mechanism is operated. A motion to move the operation member from the closed position to the first position is a same motion as a motion to move the operation member from the closed position to the second position. A movement amount of the operation member from the closed position to the first position is greater than a movement amount of the operation member from the closed position to the second position by the motion.

  • Patent number: 8359712
    Abstract: In a vehicle door outer handle device, an inwardly recessed housing recess is provided in a base member fixed to a vehicle door; an outer handle having an operation portion is pivotably supported on the base member while being able to pivot to an operated position in accordance with pulling of the operation portion and being spring-biased toward a non-operated position side, at least part of the operation portion being disposed in the housing recess; and a cylinder lock is mounted on the base member so that a key hole is covered at least in a state in which the outer handle is in the non-operated position. In the outer handle device, a cover member is detachably mounted on the base member so as to cover the key hole, the cover member being formed as a separate body from the outer handle so as to form part of the housing recess while forming a design surface of the base member.
