MOTOR

PROBLEM TO BE SOLVED: To provide a highly-reliable motor by suppressing generation of abnormal noise and suppressing a slide loss at a bearing part to a low level even when a drive load is large.SOLUTION: In a motor 1, a bearing mechanism 7 includes: a ball 76 fixed to an end part 52 of a rotary shaft 50; and a bearing member 70 having a recessed part 71 rotatably supporting the rotary shaft 50 via the ball 76. An endmost part (an end surface 520) in the motor axial line direction L located at a side closest to the bearing member 70, of the rotary shaft 50 is located on an opposite side to the bearing member 70 from the maximum diameter part of the ball 76. An inner peripheral side surface 73 of the recessed part 71 of the bearing member 70 is located at the radial outside of the maximum diameter part of the ball 76. As a result, even when the bearing mechanism 7 is configured by utilizing the ball 76, positional deviation between the rotary shaft 50 and the ball 76 is not generated. In addition, unlike in the case of performing working such as cutting and grinding on the end part of the rotary shaft 50 to form a bearing hemisphere part, a surface roughness of the ball 76 is small.
