<P>PROBLEM TO BE SOLVED: To provide an endoscope mounting fixture by which the flexibility of the insertion part of an endoscope is maintained, and the bending operation of the bend is made to be performed smoothly. <P>SOLUTION: A first propulsion section 11a and a second propulsion section 11b are connected by a three-layer coil spring 52 for connecting. When a worm gear 44 rotates at the second propulsion section 11b, the three-layer coil spring 52 for connecting integrally rotates, and the worm gear 44 of the first propulsion section 11a is also rotated collectively. Since the torque of the worm gear 44 of the second propulsion section 11b is transmitted by the three-layer coil spring 52 for connecting, the torque can be efficiently transmitted to the worm gear 44 of the first propulsion section 11a. Moreover, since the three-layer coil spring 52 for connecting bends with the bend 20 by the flexibility, the first propulsion section 11a and the second propulsion section 11b follow the bending of the bend 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
