An insertion device is provided with a pull wire (10), a joystick (8), a pulley (21) which can apply pull assist force to the pull wire (10) by the rotation of the pulley (21), and a C-ring (22) which transmits the rotation of the pulley (21) to the pull wire (10) by coming into contact, with frictional force, with the pulley (21) as an input operation is performed by the joystick (8). The cutout (K) of the C-ring (22) is provided with an end (22it) for removing friction powder from the pulley (21), the friction powder being cut from the pulley (21) when the C-ring (22) comes into contact with the pulley (21). |
