PROBLEM TO BE SOLVED: To provide a mounting structure of a flexible member in which a mounting operation of the flexible member becomes easy.SOLUTION: A protrusion 2 is formed at an upper end of a cylindrical body 1. A mounting hole 5 is formed at a lower end of a flexible member 4. The flexible member 4 is attached at an upper end part of the cylindrical body 1 only by fitting an outer peripheral surface of the protrusion 2 into an inner peripheral surface of the mounting hole 5. The outer peripheral surface of the flexible member 4 includes: a large diameter part 41 formed at the upper end part; a small diameter part 42 extended below the large diameter part 41; and a step part 43 formed between the large diameter part 41 and the small diameter part 42. The mounting hole 5 is opened from the lower end of the small diameter part 42. A restraint wall part 3 of a cylindrical body shape surrounding the outer peripheral surface of the protrusion 2 is provided at the upper end part of the cylindrical body 1. When the outer peripheral surface of the protrusion 2 is fitted into the inner peripheral surface of the mounting hole 5, the step part 43 contacts with an upper end of the restraint wall part 3 in a shaft direction, and an outer periphery surface of the small diameter part 42 and an inner peripheral surface of the restraint wall part 3 are in a noncontact state each other.SELECTED DRAWING: Figure 2 |
