Abstract
An endoscope includes a flexible tube section including coiled tubes, a motor disposed on a proximal side of the flexible tube section, a driving force transmission unit disposed on a distal side of the flexible tube section, and a drive shaft provided inside the flexible tube section along a long axis, the drive shaft being caused to perform rotation around the long axis by a driving force of the motor and to transmit the rotation of the motor to the driving force transmission unit, where torsional resistance of the flexible tube section around the long axis is set higher than torsional resistance between a relay gear of the motor and a drive gear of the driving force transmission unit through the drive shaft.
