An automatic opening/closing apparatus for vehicle, which is provided with a tensioner mechanism for applying a predetermined tension to a cable member, is downsized. A case of a driving unit is provided with a tensioner housing, and the tensioner mechanism for applying the predetermined tension to a cable is accommodated in the tensioner housing. The tensioner mechanism includes a pulley holder movably mounted on a guide shaft, and a spring for biasing the pulley holder, wherein a movable pulley is rotatably supported by the pulley holder. The cable drawn in the tensioner housing is wound about the movable pulley so that a direction in which the cable is drawn out from the case is substantially parallel to a direction in which the cable is drawn out from a driving drum, whereby the predetermined tension is applied to the cable by a spring force of the spring.

Automatic opening/closing apparatus for vehicle

An automatic opening/closing apparatus for vehicle is downsized, and cost of the automatic opening/closing apparatus is reduced by reducing the number of its components. A driving drum is rotatably accommodated in a main body case of a driving unit, and one ends of cables are connected to a sliding door and the other ends are wound around the driving drum. An electric motor is attached to the main body case, and the driving drum is driven for rotation. A tensioner mechanism applying a predetermined tension to the cables is accommodated in the main body case. A control device, including a control substrate and a substrate case for accommodating the control substrate, is disposed to be overlapped on an axial-directional side of the driving drum to a portion of the main body case for accommodating the tensioner mechanism, whereby an operation of the electric motor is controlled by the control device.
