- both end surfaces in the axial direction of the bulging portion 62b abut against the inner surfaces of the cover 64b and the cap 64a, and the bulging portion 62b is compressed in the axial direction.
- the bulging portion 62 b is sandwiched between the cover 64 b and the cap 64 a, and the outer peripheral surface of the cushion 65 is fixed to the inner surface of the housing 64.
- a clearance is formed between the axial end surface of the large diameter portion 66 and the inner surface of the cover 64b or the cap 64a.
- the dimensions of the internal space (radius) l 2 is longer by a predetermined length than the dimension l 1 described above.
- the axial rigidity of the cushion 65 can be lowered while appropriately positioning the hub 12 and the outer cable 34 in the cable axial direction.
- a clearance is formed between the outer peripheral surface of the bulging portion 62b and the inner peripheral surface of the housing 64.
- the outer peripheral surface of the bulging portion 62b and the housing 64 The inner peripheral surface may be in contact.
- the dimension l 1 of the cushion 65 (dimension in a state where no external force acts) is shorter than the dimension l 2 of the internal space of the housing 64. That is, before the cushion 65 is accommodated in the housing 64, it is preferable that the clearance be formed between the outer peripheral surface of the bulging portion 62b and the inner peripheral surface of the housing 64.
- the cushion 65 when the cushion 65 is accommodated in the housing 64, a large force is not generated between the outer peripheral surface of the bulging portion 62b and the inner peripheral surface of the cover 64b. Therefore, the axial rigidity of the cushion 65 can be effectively reduced. Moreover, it is good also as a state (state where the force produced between both) is only touching the outer peripheral surface of the bulging part 62b, and the inner peripheral surface of the cover 64b.
- the convex portion is formed on the outer peripheral surface of the small diameter portion of the cushion, but the convex portion may be formed on the inner peripheral surface of the housing. Even with such a configuration, the hub and the outer cable can be prevented from being inclined.
- a step 84 a may be formed in the small diameter portion of the cushion 84, and a step 82 a in contact with the step 84 a may be formed on the inner surface of the housing 82. Then, the hub and the outer cable may be restricted from being displaced in the axial direction by contacting the step 84a of the small diameter portion of the cushion 84 with the step 82a of the inner surface of the housing 82.
- the thickness of the flange portion 80b of the hub 80 may be configured to increase from the outer peripheral side toward the inner peripheral side.
