Abstract
An endoscope includes a bendable part having a first bendable portion, a second bendable portion, a flexible tube part, and an operation unit. An upward coil is attached at its distal end on the second bendable portion. A second coil is attached at its distal end on the flexible tube part and at its proximal end in the operation unit. An upward coil receiver is disposed in the operation unit with the upward coil being connected to the upward coil receiver. A selection member presses the upward coil receiver and compresses the upward coil. A bent length selection wire is connected to the selection member. A selection pulley is disposed in the operation unit and is configured to allow the upward coil receiver to advance or retract via the selection member. A cam plate having cam portions is formed to increase a frictional force with rotation of the selection pulley.
