Claims

[Claims for Utility Model Registration] (1) The inner rings of two ball bearings spaced apart in the axial direction are fixed at predetermined positions on the rotating shaft, and
In a motor having a ball bearing in which the outer ring parts of the ball bearings are fixed to a housing part with an axial pressing force applied between the outer ring parts, the material of the housing is set to have a coefficient of thermal expansion of the ball bearing. A motor having ball bearings having the same coefficient of thermal expansion. (2) The inner rings of two ball bearings spaced apart in the axial direction are fixed at predetermined positions on the rotating shaft, and the
In a motor having a ball bearing in which the outer ring parts of the ball bearings are fixed to a housing part while applying an axial pressing force between the outer ring parts, the material of the housing and the rotating shaft is A motor having a ball bearing, characterized in that the motor has a coefficient of thermal expansion that is the same as a coefficient of expansion.
