Lid opening and closing device for a vehicle

A lid opening and closing device for a vehicle, comprising

• a lid that is configured to be pivotably supported on a vehicle body exterior plate,
• a case that is configured to be mounted on the vehicle body exterior plate,
• a rod that can move forward and backward between a pushed-in position in response to the lid being pushed in and a protruding position when the lid is in an open state, the rod being supported on the case so that the rod can attain a lid closed position at which the rod returns from the pushed-in position toward the protruding position side only by a predetermined amount of movement when the lid is in a closed state,
• a coupling member operatively attached to the rod and axially relatively non-movable in relation to the rod,
• an urging member that urges the rod from the pushed-in position toward the protruding position side and is provided between the case and the rod,
• an axial position-restricting groove that has a pin-receiving portion facing the protruding position side and is formed on the rod or on the coupling member, and
• a rod axial direction restricting mechanism comprising the axial position-restricting groove and an elastic member that has a pin thereon which is inserted into the axial position-restricting groove while being capable of being received by the pin-receiving portion in a state in which the rod is at the lid closed position, and that exhibits a resilient force making the pin resiliently abut against the rod or the coupling member, the rod axial direction restricting mechanism restricting an axial position of the rod while enabling the pin to be disengaged from the pin-receiving portion in response to an operation of pushing in the lid in a closed state,
• the case being integrally provided with a restricting part configured to restrict displacement of the elastic member to a side on which the pin is disengaged from the axial position-restricting groove, the restricting part being capable of abutting against the elastic member,
• wherein when a force is applied to the lid at the lid closed position thereof, the pin is not disengaged from the axial position-restricting groove;
• and
• wherein the elastic member comprises a plate-shaped portion that extends lengthwise in a longitudinal direction of the rod, a base end portion comprising a shaft, and a free end portion comprising the pin;
• the base end portion is attached to the case via the shaft, such that the elastic member pivots within a predetermined range within the case;
• and
• the elastic member is integrally formed.
