Abstract

A medical device that can prevent the rotating operation part from rotating more than the operator's intention and improve the operability to control the direction of the head of the tubular member is provided. The medical device includes a flexible tubular member and a rotating operation part that deflects the head of the tubular member in a first direction when rotating in positive rotation direction and deflects the head of the tubular member in a second direction when rotating in negative rotation direction opposite to the positive direction. A handle case is gripped when the rotating operation part is rotated. An O-ring that is placed between the rotating operation part and the handle case produces frictional force between the rotating operation part and the handle case when the rotating operation part is rotated.
