ROTATING MEMBER FIXING STRUCTURE

摘要

A rotating member fixing structure includes a shaft member and a rotating member. The rotating member has an axial bore section press-fitted to the shaft member. One of the shaft member and the axial bore section of the rotating member includes a margin adjusting part dimensioned to reduce a press-fitting margin between the shaft member and the axial bore section of the rotating member from an initial press-fitting margin to an effective press-fitting margin that is less than or equal to a prescribed value when the rotating member is press-fitted to the shaft member.
