A motor mounting structure is disclosed, by which a central axial line of output shaft can be maintained at the optimum axial position when the motor is mounted on an external device without finishing the motor with high precision. Motor is mounted on actuator by inserting output shaft of motor in insert hole of actuator and fitting the exposed part of radial bearing in engaging recess. In addition, since the engaging surface of engaging recess is finished with high precision relative to radial bearing which have already been finished with high precision, the axial line position of output shaft of motor is brought to the optimum axial line position when motor is mounted on actuator. Therefore, motor can be positioned and connected without finishing the external peripheral surface of body case with high precision.
