<P>PROBLEM TO BE SOLVED: To provide a mounting structure of a flexible member in which the mounting operation of the flexible member becomes easy. <P>SOLUTION: A protrusion 2 is formed at the upper end of a tube 1. A mounting hole 5 is formed at the lower end of a flexible member 4. The flexible member 4 is attached at the upper edge of the tube 1 by only the fit of the periphery of the protrusion 2 and the inner circumference surface of the mounting hole 5. The periphery of the flexible member 4 includes: a large diameter part 41 formed at the upper edge; a small diameter part 42 extended below this 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 portion 3 of a tube shape surrounding the periphery of the protrusion 2 is formed to the upper edge of the tube 1. When carrying out the fit of the periphery of the protrusion 2 and the inner circumference surface of the mounting hole 5, the step section 43 and the upper end of the restraint wall portion 3 contact in the shaft direction, and the outer periphery surface of the small diameter part 42 and the inner circumference surface of the restraint wall portion 3 are in a noncontact state. <P>COPYRIGHT: (C)2009,JPO&INPIT |
