ROTATING MEMBER FIXING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a rotating member fixing structure fixing a rotating member to a shaft member by press-fitting while inhibiting generation of local stress concentration.

SOLUTION: This rotating member fixing structure fixes a rotating member 7 having an axial bore 17 to a shaft member 1b by press-fitting. The rotating member 7 is press-fitted to the axial member 1b with adjusting a press-fitting margin while cutting a bottom surface 18b of an inner tooth of the rotating member 7 by a trigger 24 formed on an outer circumference of the shaft member 1b to make the press-fitting margin between the shaft member 1b and the axial bore 17 less than or equal to a predetermined value.
