The insertion device according to the present invention is provided with: a shaft part for rotating about a shaft axis by a motive force for causing an operating part to operate, and thereby transmitting the motive force from a first extension direction to a second extension direction; and a sheathing part for covering an external surface of the shaft part. The insertion device is provided with a speed-reducing part for increasing a drive torque applied in operation by the motive force and transmitting the motive force for which the drive torque was increased toward the operating part. A constant resistance is imparted to the rotating shaft part by a resistance part provided between the external surface of the shaft part and an internal surface of the sheathing part. |
