PROBLEM TO BE SOLVED: To provide a mounting structure of a shaft member capable of sufficiently enduring large torque and reducing the generation of slapping sound even when the direction of torque acting thereon is suddenly changed. SOLUTION: Second torque acting portions 34a, 34b are fitted to second fitting portions 24a, 24b and first torque acting portions 32a-32c are fitted to first fitting portions 22a, 22c in a state that spring members 40a, 40b are mounted in such manner that right and left top portions of "M" shape of the spring members 40a, 40b are kept into contact with bottom portions of the second fitting portions 24a, 24b, and lower central end portions of the "M" shape are kept into contact with receiving portions of the top portions of the second torque acting portions 34a, 34b. As looseness is comparatively slowly eliminated by elastic deformation of the spring members 40a, 40b even when the acting torque is suddenly changed, the generation of slapping sound generated at that time can be reduced. Further the large torque can be received by the first fitting portions 22a-22c through the first torque acting portions 32a-32c. COPYRIGHT: (C)2007,JPO&INPIT
