PROBLEM TO BE SOLVED: To provide a clamp certainly closing a flow passage of a tube without looseness on the upper side and the lower side of the tube when closing the flow passage of the tube.SOLUTION: A base part 2 has a base end connection part 7PE and an end connection part 7DE, the base end connection part 7PE is formed with a movable part 3, and the end connection part 7DE is formed with a base part side engagement part 9 having a base part side engagement auxiliary part 9T. The base part 2 has a base part side tube press part projection part 2.1T and a tube holding part 5, and the movable part 3 has a movable part side engagement part 8 including a movable part side tube press part projection part 6T and a pair of guide parts 8G (8S1G, 8S2G). The tube holding part 5 has a first side wall 5S1W, a second side wall 5S2W, an end side wall 5DEW, and a base end side wall 5PEW, and they form a tube holding space SP. A tube T is pressed between the movable part side tube press part projection part 6T and the base part side tube press part projection part 2.1T inside the space SP, so that a flow passage of the tube T is closed.COPYRIGHT: (C)2013,JPO&INPIT【課題】チューブの流路を閉塞する際、チューブの上部側と下部側でガタツキがなく、確実に閉塞できるクランプを提供すること。【解決手段】基部2は基端連結部7PEと末端連結部7DEを有し、基端連結部7PEに可動部3を形成し、末端連結部7DEに、基部側係合補助部9Tを有する基部側係合部9を形成している。基部2は基部側チューブ押圧部突部2.1Tとチューブ保持部5を有し、可動部3は、可動部側チューブ押圧部突部6Tと、一対のガイド部8G(8S1G、8S2G)を備えた可動部側係合部8を有する。チューブ保持部5は、第1側壁5S1W、第2側壁5S2W、末端側壁5DEW及び基端側壁5PEWを有し、これらによりチューブ保持空間SPを形成し、チューブTは、当該空間SP内で、可動部側チューブ押圧部突部6Tと基部側チューブ押圧部突部2.1Tとの間で押圧され、チューブTの流路は閉塞される。【選択図】図1
