Door opening/closing device

1. A door opening/closing device for a slide door that permits an opening movement of the slide 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 and releases the open-door holding mechanism when being turned to a second direction arranged on a base plate by a rotating shaft member, and 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; and

a link member, arranged between the door operating lever and the open-door holding mechanism and connected to the door operating lever and a connecting member, one end of which is connected to the link member and the other end of which is connected to the open-door holding mechanism to connect the link member and the open-door holding mechanism to each other, and when the door operating lever is turned to the second direction, the link member releases the open-door holding mechanism via the connecting member,

wherein the closed-door holding mechanism holds the slide door in a closed state with respect to the vehicle body, and is provided between a rear edge portion of the slide door and the vehicle body, and

wherein the open-door holding mechanism holds the slide door in an open state with respect to the vehicle body, and is provided between a support frame on the slide door and the vehicle body.

2. The door opening/closing device according to claim 1 , further comprising a second door-operating lever that releases the closed-door holding mechanism and releases the open-door holding mechanism when an outside handle is operated arranged on the base plate by a second rotating-shaft member,

wherein the link member is connected to a third rotating-shaft members, one end of which is connected to the door operating lever and the other end of which is arranged on the second door-operating lever.

3. 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 and releases the open-door holding mechanism when being turned to a second direction arranged on a base plate by a rotating shaft member, and 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;

a link member, arranged between the door operating lever and the open-door holding mechanism and connected to the door operating lever and a connecting member, one end of which is connected to the link member and the other end of which is connected to the open-door holding mechanism to connect the link member and the open-door holding mechanism to each other, and when the door operating lever is turned to the second direction, the link member releases the open-door holding mechanism via the connecting member; and

a second door-operating lever that releases the closed-door holding mechanism and releases the open-door holding mechanism when an outside handle is operated arranged on the base plate by a second rotating-shaft member,

wherein the link member is connected to a third rotating-shaft member, one end of which is connected to the door operating lever and the other end of which is arranged on the second door-operating lever.
