摘要： PROBLEM TO BE SOLVED: To provide a rotary unit having improved durability. SOLUTION: The rotary unit comprises a supporting member rotatably arranged and having a fitted-in portion, a shaft member having fitting-in portions at both ends and a body between the fitting-in portions and fitted at the fitting-in portions in the fitted-in portion, and a rotor arranged rotatably with the shaft member. The hardness of the body of the shaft member is higher than the hardness of each fitting-in portion and a hardness difference between the body and each fitting-in portion is greater than a hardness difference between each fitting-in portion and the fitted-in portion. In this case, the hardness difference between the fitting-in portion and the fitted-in portion is smaller, thus preventing the wear of the supporting member on the inner peripheral face of the fitted-in portion. As a result, the rotary unit has improved durability. COPYRIGHT: (C)2008,JPO&INPIT
