PROBLEM TO BE SOLVED: To obtain a motor apparatus of simplified structure which can suppress noise and vibration of a motor shaft. SOLUTION: This motor apparatus comprises a motor body; a motor shaft which includes an inserting end located within the motor body and a projecting end projected from the motor body, and is supported to move forward and backward in the axial direction to change amount of projection from the motor body; a movement regulating surface provided within the motor body to be placed in contact with the inserting end of the motor shaft; a gear case to fix the motor body and support a reduction gear column to transfer the rotation of the motor shaft; and an elastic pushing portion which may be elastically deformed in the moving directions of the motor shaft, provided within the gear case to be in contact with the projecting end of the motor shaft and to push the motor shaft toward the inside of the motor body under the free condition to place the inserting end in contact with the movement regulating surface. The elastic pushing portion is elastically deformed to keep in contact with the protruding end, when the motor shaft is displaced in the increasing direction of the protrusion from the motor body.
