Automatic opening/closing apparatus for vehicle

摘要

A cost-reduced, downsized automatic opening/closing apparatus for vehicle is achieved by reducing the number of components thereof. A case (25) of a driving unit (22) is provided with a drum housing portion (31), and a driving drum (41) is rotatably accommodated in the drum housing portion (31). An electric motor (27) is attached to the case (25), and the driving drum (41) is driven for rotation by the electric motor (27). A cable (24) connected to a sliding door is wound around the driving drum (41). By rotation of the driving drum, the sliding door is opened and closed as being drawn by the cable. The case is provided with a substrate housing portion (46) integrally with the drum housing portion, and a control substrate (47) for controlling an operation of the electric motor is accommodated in the substrate housing portion (46).
