Abstract:
An apparatus comprising:a motor adapted to be fitted to a vehicle body;a kinetic conversion mechanism for converting a torque of said motor into a linear motion to thereby output the linear motion;a coupling member adapted for coupling an output portion of said kinetic conversion mechanism to a vehicle door pivotally connected to the vehicle body with a hinge shaft, so that the vehicle door can be opened and closed via said kinetic conversion mechanism and said coupling member by the torque of said motor,wherein said kinetic conversion mechanism comprises:a driving pulley pivotally connected to one end portion of a board which is pointed in a direction substantially crossing said hinge shaft, coupled to the output shaft of said motor and capable of forward and reverse rotation;a driven pulley pivotally connected to the other end of said board; andan endless transmission member wound on said driving pulley and said driven pulley, wherein said coupling member is coupled to a part of the endless transmission member as the output portion thereof,wherein said kinetic conversion mechanism and said motor are arranged in an L-shape by coupling motor to one end portion of said kinetic conversion mechanism at substantially right angle.
