PROBLEM TO BE SOLVED: To facilitate attachment of an adjusting assembling body by providing a flexible motion transmitting core element and a component for adjusting the total length of first and second conduit parts, and pressing the component by a spring in order to shorten the total length. SOLUTION: A male-type member 19 and a female-type member 20 constitute an insert-type adjusting component for connecting first and second conduit parts to each other in order to adjust the total length of the first and second conduit parts. The male-type member 18 includes adjusting teeth 21, and a locking member 19 is supported by the female-type member 20 so as to be engaged with the teeth 21 in the locking position to prevent the movement. The locking member 19 is formed into a U shape and provided with teeth 23 to be engaged with the teeth 21 in its leg inner sides. Hooks 25 are arranged on the far end of the legs, and the female-type member 20 is provided with fasteners 28 to be engaged with the hooks 25 to lock the locking member 19 in the locking position. A sprint 22 interacts with the male-type and female- type members 18, 20 and presses both members to each other, and the total length of the first and second conduit parts can be shortened. A retainer 24 for holding the spring 22 into the compressed state is arranged during the assembly of the inserttype member. |
