PROBLEM TO BE SOLVED: To house a vibration absorbing material structure in a motor without changing entire length of the motor, and to maximize the high speed response characteristics of a hybrid stepping motor. SOLUTION: A front cover 1 and a rear cover 2 of a motor are formed separately: bearing portion 5 and cover portion, a fitting portion inserted into the inner diameter of the stator of the motor is provided at a part of the bearing portion, and the front and rear covers are constituted by interposing an elastic body in the fitting gap of the two bodies, thus obtaining a structure for absorbing vibration in the motor.
