PROBLEM TO BE SOLVED: To provide a cleaning adapter which does not drop during cleaning and is easily mounted on the endoscope.SOLUTION: An adapter body 52 includes a roughly columnar support part 57, a connection cylinder part 58, and a supply cylinder part 60. The connection cylinder part 58 is attached to the support part 57 eccentrically to the center axis S2 of the support part 57. A holding cylinder 53 holds the adapter body 52 freely rotatably and freely movably in a center axis direction. A lock member 54 has an opening into which a mouth ring can be inserted toward the connection cylinder part 58. A coil spring 66 energizes the adapter body 52 to the holding cylinder 53 toward the side of the connection cylinder part 58. A locking part is provided on the opening of the lock member 54. By the relative rotation of the holding cylinder 53 and the adapter body 52, the locking part is displaced to a locking position where the locking part is locked to the flange part of the mouth ring and an unlocking position where the lock of the locking part is released. Since a part of the flange part is pressed by the locking part at the locking position, the washing adapter 2 does not drop from the mouth ring. |
