An operating wire is inserted in a close-contact coil in a bendable tube portion through a flexible tube portion. The close-contact coil is such that a fixed portion is provided at the position of a bending piece which is placed at the most base end of the bendable tube portion, and that a close-contact coil extension portion having been put in a non-fixed state extends from the fixed portion in the bendable tube portion. A part between a fixed portion and the fixed portion of the close-contact coil is a remote control cable for transmitting an amount of pushing and pulling an operating wire when operating an operating wire. A close-contact coil extension portion extended from the fixed portion at the side of a tip end of the close-contact coil functions as a positioning guide section for holding the operating wire so as to prevent the operating wire from being displaced in a circumferential direction. |
