Abstract
A motor deice for actuating a vehicle door operation device is operated by the rotational torque inputted from a electric motor to operate a latch mechanism. The rotational torque of the motor is inputted to a sun gear body of a planetary gear mechanism to rotate each of several planetary gears via a ring gear body fixed against rotation. A carrier is rotated by the rotation of the planetary gears and an output shaft operates the latch operation mechanism. The ring gear body is fixed against rotation by engaging an engagement-disengagement block with an outer gear portion through application of a force of a spring. By applying the opening operation to a door handle, an engagement-disengagement operation member is rotated to retract the engagement-disengagement block. Then, the ring gear body is released to be rotated to interrupt a power transmission condition between the motor and the output shaft.
