LID OPENING AND CLOSING DEVICE FOR A VEHICLE

In a lid opening and closing device for vehicle, a rod can move forward and backward between pushed-in and protruding positions, and is supported on a case so that the rod can attain a lid closed position where the rod returns from pushed-in position toward protruding position only by predetermined movement amount. An axial position-restricting groove has a pin-receiving portion and is formed on the rod or a coupling member. An elastic member has a pin inserted into the groove while being receivable by the portion when the rod is at lid closed position, the elastic member being supported on the case and exhibiting resilient force making the pin resiliently abut against the rod or coupling member. The case is provided with a restricting part capable of abutting against the elastic member, and restricting displacement of the elastic member to a side where the pin is disengaged from the groove.
