Zusammenfassung:An overtube for an endoscope includes a tube body, a balloon, a first-communication-path, a second-communication-path, a first-mouthpiece, a second-mouthpiece, a first-connection-section which is provided on the first-mouthpiece, and a second-connection-section which is provided on the second-mouthpiece. The balloon is dilatably/deflatably provided on the tube body. The first-communication-path extends from a distal-end-portion toward a proximal-end-portion of the tube body in a state in which the first-communication-path communicates with the balloon. The second-communication-path extends from a hollow-portion toward the proximal-end-portion of the tube body. The first-mouthpiece projects from the tube body and includes a path communicating with the first-communication-path. The second-mouthpiece projects from the tube body and includes a path communicating with the second-communication-path. The first-connection-section is connected to a first-feed-portion of a fluid-feed-mechanism and is prevented from being connected to a second-feed-portion of the fluid-feed-mechanism. The second-connection-section is connected to the second-feed-portion and is prevented from being connected to the first-feed-portion.
