PROBLEM TO BE SOLVED: To provide a motor structure which achieves simplification of its structure and inhibits vibrations of a motor.SOLUTION: A motor structure includes: a motor 1 having a motor shaft 13; a transmission 3 having a gear shaft 311 which integrally rotates with the motor shaft 13 and has an outer shape forming a circular column shape; a case body 7 which houses the motor 1 and the transmission 3; a division case 8 which is fixed to the case body 7 while closing a hole h2 of the case body 7; a first bearing 6a which is disposed between an inner peripheral surface at the one end side of the motor shaft 13 and an extension part 8a in a radial direction; a second bearing 6b installed at the other end side of the motor shaft 13; and a third bearing 6c installed at the other end side of the gear shaft 311. An area near one end of the gear shaft 311 is splined to the motor shaft 13, and a portion of the gear shaft 311, which corresponds to the second bearing 6b in an axial direction, fits in the motor shaft 13. |
