PROBLEM TO BE SOLVED: To provide a technology for fixing components of a motor to each other, in which a fixing member can be singly used for fixing the members or it can be used together with various fixing methods, such as adhesion, press fitting, and shrinkage fitting.SOLUTION: A stationary part or a rotating part of a motor comprises: an outer member 21A having a substantially cylindrical inner peripheral surface around a central axis; an inner member 41A which is positioned more inside in a radial direction from the outer member 21A and has a substantially cylindrical outer peripheral surface; and a fixing member 5A having a fixing part 51A interposed between the outer member and the inner member. The fixing part 51A has: one inner contact part 512A: and two outer contact parts 511A arranged at both sides of the inner contact part 512A in a circumferential direction. The outer contact parts 511A come into contact with the outer member 21A, and the inner contact part 512A comes into contact with the inner member 41A. Compression stress in the radial direction is applied to the fixing part 51A. At least one of the outer contact parts 511A and the inner contact part 512A is bitten into the outer member 21A or the inner member 41A. |
