Abstract
A vehicle door driving apparatus includes a driving mechanism fixed to a vehicle door and including a motor and a drum rotationally driven by the motor. A rope member is wound around the drum and linked to the vehicle body, and rotation of the drum is transmitted to the vehicle body by the rope member to open and close the vehicle door. The driving mechanism includes: a first small-diameter gear linked to the rotary axis of the motor to rotate together with the rotary shaft of the motor; a transmission gear rotatable around the axis extending in the vehicle width direction; a sun gear rotatable around such axis; a ring gear disposed on the same axis as the sun gear; and a carrier having a planet gear engaging the sun gear and the ring gear, and linked to the drum so that the carrier rotates together with the drum.
