Patent attributes
There are provided a hinge arm having a lever and a rotational axis to rotate the lever so as to be projected from the door panel, and a driving unit to transmit a drive force to the hinge arm so as to project the lever from the door panel. The driving unit comprises a motor and an output axis connected to the motor and the hinge arm so as to transmit a motor output to the hinge arm in a region from a storage position to an open position, wherein the drive force is transmitted from the motor to the hinge arm via the output axis when the lever is moved from the storage position to a gripping position and the drive force is transmitted from the hinge arm to the motor via the output axis when the lever is moved from the open position to the gripping position.
