<p>A tube clamp, comprising a housing (1) having an inner cavity (2) longitudinally passed therethrough and an upper window (3) and a roller (4) fitted to the housing with its cylindrical surface positioned at the upper window and capable of longitudinally moving the inner cavity. A roller pivot shaft (5) is guided by a pair of guide grooves (6) formed along the upper window. A space between the bottom face (7) of the inner cavity and the guide grooves is smaller than an open area (7a) in a narrowed area (7b). When the roller is positioned in the narrowed area, a tube (11) is closed since it is held and pressed between the roller and the bottom face, and when the roller is positioned in the open area, the flow passage of the tube is opened. Also, the tube clamp comprises a slider (8) fitted to the upper part of the roller and movable in the hollow cavity together with the roller. The slider comprises a slider pivot shaft (9) engaged with the guide grooves in its rear end part side face and a bearing cutout (10) engaged with the roller pivot shaft for holding the roller in its front end part lower face. Thus, the tube clamp can be easily operated with a light force, and can sufficiently act a closing force on the tube.</p> |
