PROBLEM TO BE SOLVED: To provide a motor in which vibration of a rotor can be suppressed.SOLUTION: A motor case 11 includes: a first bearing housing part 25; and a second bearing housing part 32. A rotor 81 disposed in the motor case 11 includes a rotary shaft 82 having an output end portion 82a for outputting rotation at one axial-direction end portion. The first bearing housing part 25 houses a first ball bearing 51. The first ball bearing 51 is disposed to have a buffer clearance between the first bearing housing part 25 and the first ball bearing 51 and journals the rotary shaft 82. The second bearing housing part 32 houses a second ball bearing 61. The second ball bearing 61 engages with the inner peripheral surface of the second bearing housing part 32 and engage with the outer peripheral surface of the rotary shaft 82 at a position closer to the output end portion 82a than the first ball bearing 51, and journals the rotary shaft 82. Elastic members 101 having elasticity are disposed at two axially separated positions in the buffer clearance. The elastic members 101 are continuous in a circumferential direction, and are in contact with both of the first ball bearing 51 and the first bearing housing part 25. |
