PROBLEM TO BE SOLVED: To reduce generation of backlash between a bearing and a shaft caused by a thrust.SOLUTION: An electric motor 1 comprises a shaft 10, a bearing 4A, a tubular collar 50 and a bearing mounting member 12. The shaft 10 is mounted to a rotor core 20, extends in a direction of a rotation center axis Zr of the rotor core 20 and can be mounted with a gear 71 at a side of one end portion 10C. The bearing 4A supports, in a rotatable manner, the shaft 10 to a casing 3 closer to the gear 71 than the rotor core 20. The collar 50 is mounted to an outer peripheral part of the shaft 10 and between the bearing 4A and the gear 71. The bearing mounting member 12 is mounted from a side of the rotor core 20 to the inside of the casing 3 and mounts the bearing 4A to the casing 3. |
