Abstract

A door opening/closing device includes a door operating lever that releases a closed-door latch unit when being turned to a first direction and releases an open-door latch unit when being turned to a second direction is arranged on a base plate by means of an inside-handle lever shaft. Also, an operation output unit is formed on an inside handle so as to engage with the door operating lever. When the inside handle is operated to open or close the door, the door operating lever is turned in a desired direction by bringing the operation output unit into contact with the door operating lever. Furthermore, a lower open lever that transmits the turning operation to the second direction of the door operating lever to the open-door latch unit is arranged on the base plate by means of the inside-handle lever shaft.

Claims (9)

1. A door opening/closing device that permits an opening movement of a door with respect to a vehicle body by releasing a closed-door holding mechanism when an inside handle is operated to open the door, and that permits a closing movement of the door with respect to the vehicle body by releasing an open-door holding mechanism when the inside handle is operated to close the door, the door opening/closing device comprising:

a door operating lever that releases the closed-door holding mechanism when being turned to a first direction in a first turning operation and releases the open-door holding mechanism when being turned to a second direction in a second turning operation arranged on a base plate by a rotating shaft member;

an operation output mechanism formed on the inside handle so as to engage with the door operating lever, wherein, when the inside handle is operated to open or close the door, the door operating lever is turned in a desired direction by bringing the operation output mechanism into contact with the door operating lever, wherein the operation output mechanism is inserted into an engagement hole in the door operating lever and through an insertion window hole of the base plate;

an intermediate lever that transmits the second turning operation of the door operating lever to the open-door holding mechanism arranged on the base plate by the rotating shaft member, wherein the door operating lever contiguously engages with the intermediate lever; and

an operating handle member of the inside handle disposed on an operation shaft member extending in an up and down direction of the vehicle body,

wherein the rotating shaft member around which the intermediate lever rotates is arrange about a pivot axis of the door operating lever and a link lever, and

wherein the rotating shaft member is arranged in a direction perpendicular to the operation shaft member.

2. The door opening/closing device according to claim 1 , further comprising a wire cable connecting the intermediate lever to the open-door holding mechanism.

3. The door opening/closing device according to claim 2 , wherein, when the wire cable is pulled, the open-door holding mechanism is released.
