Patent ID: 7815242

Claim:
An automatic opening/closing apparatus for vehicle, automatically opening and closing an open/close member provided to a vehicle body, the apparatus comprising: a main body case disposed in the vehicle body; a driving rotor member accommodated in the main body case, and driven for rotation by a driving source; a cable member whose one end is wound around the driving rotor member and whose the other end is connected to the open/close member; a tensioner mechanism accommodated in the main body case so as to be adjacent to the driving rotor member in a diameter direction, the tensioner mechanism applying a predetermined tension to the cable member; and a control device disposed so as to be overlapped on an axial-directional side of the driving rotor member with respect to a portion of the main body case for accommodating the tensioner mechanism, the control device controlling an operation of the driving source, wherein the main body case is provided with a reduction-mechanism housing accommodating a reduction mechanism for decelerating rotation of the driving source, and the control device is provided in a side direction of the reduction-mechanism housing, wherein the main body case, the reduction-mechanism housing and the tensioner housing are formed into such an approximately L shape in section as to be disposed in the axial direction and the diameter direction with respect to the drum housing, respectively, and wherein the control device is disposed in a dead space obtained by partitioning a portion where the reduction-mechanism housing is provided and a portion where the tensioner housing is provided in the main body case.
