PROBLEM TO BE SOLVED: To provide a clamp having excellent operability when being closed and pressing/clamping a tube and having favorable operability when being opened.SOLUTION: The clamp includes a base part 2 and a movable part 3, where the base part 2, along with a base part-side tube pressing projection 2.1T, is formed into a tube holding part 5, and the movable part 3, along with a movable part-side tube pressing projection 6T, is formed into a movable part-side engagement part 8. The movable part-side tube pressing projection 6T includes a bend part 6TR formed on a lower side, and a pair of projections 6TT formed at lateral portions of the bend part 6TR. A movable part-side engagement wall 8W and a base part-side engagement wall 9W are engaged with each other, and the projections 6TT are inserted into side wall grooves 5WSM of the tube holding part 5, so that a tube T is pressed and clamped in a tube holding space 5SP between the bend part 6TR of the movable part-side tube pressing projection 6T and a bend part 2.1R of the base part-side tube pressing part 2.1, and a passage of the tube T is closed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】閉じてチューブを押圧・挟持する時の操作性に優れ、開放する時も操作性が良いクランプを提供すること。【解決手段】基部2と可動部3を有し、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を形成し、可動部3は可動部側チューブ押圧部突部6Tと可動部側係合部8を形成している。可動部側チューブ押圧部突部6Tは下部に湾曲部6TRを形成し、湾曲部6TRの側部に一対の突起6TTを形成している。可動部側係合壁8Wと基部側係合壁9Wとを係合し、かつ突起6TTがチューブ保持部5の側壁溝5WSMに挿入されることにより、チューブTはチューブ保持空間5SP内で、可動部側チューブ押圧部突部6Tの湾曲部6TRと基部側チューブ押圧部2.1の湾曲部2.1Rとの間で押圧・挟持され、チューブTの流路は閉塞される。【選択図】図1
