Abstract
An endoscope includes an insertion unit, an operation unit, an operation-unit engagement part, an insertion-unit engagement part, a water-tight sealing member, and a torque control member. The torque control member is provided between the operation-unit engagement part and the insertion-unit engagement part in radial directions of the insertion unit, so as to make tight contact with the operation-unit engagement part and the insertion-unit engagement part, and controls resistive torque of the insertion unit during rotation of the insertion unit by applying frictional resistance of a direction about the axis to the insertion unit when the insertion unit rotates in relation to the operation unit.
