Abstract: A valve unit is switchable to an open position at which an outside of an exterior portion and an inner cavity communicate with each other and a closed position at which a communication between the outside of the exterior portion and the inner cavity is blocked in an endoscope. In the endoscope, an electric power is supplied to a drive force generation section only when a connection portion of an universal cord is connected to a peripheral device, and the drive force generation section generates a drive force to drive the valve unit by a supply of the electric power. The valve unit moves from the closed position to the open position by the drive force generated by the drive force generation section.

Abstract: An endoscope includes a first breakable portion provided between a part of an outer peripheral surface of a distal rigid section main body and a second inner peripheral surface, and including a fragile portion which is formed in a concaved-shape and which is more easy to break than any other part of the outer peripheral surface except for thereof. The endoscope includes a second breakable portion provided between a first inner peripheral surface and the second inner peripheral surface, and a third breakable portion provided between the first inner peripheral surface and a part of the outer peripheral surface of the distal rigid section main body, which differs from the fragile portion.
