PROBLEM TO BE SOLVED: To reduce noise, and to enhance the vibration proofing property of a motor against vibration from outside by absorbing vibration of its rotor and stator generated when the motor rotates. SOLUTION: A holding means 16 for holding a rotor and a stator is fixed to the body 19 of a control circuit case with vibration absorbing members 26, 27 having a plurality of ribs 33 in between. The ribs 33 are formed projecting radially to the rotation center of the rotor, and are easy to fall in the directions (a), (b) of forward and reverse rotation of the rotor, and difficult to fall in directions other than those. Since the direction of vibration of the rotor and the stator generated when the motor rotates is the direction of its rotation, the vibration is absorbed by the easiness of falling of the ribs 33 as if the ribs 33 were soft. The ribs 33 become difficult to fall against vibration from outside, as holding-out force is generated in the ribs 33, and the vibration proofing property is enhanced. |
