<p>A tube clamp includes a housing 1 that has an inner cavity 2 longitudinally passing through the housing 1 and an upper window 3, and a roller 4 that is mounted in the housing with its cylindrical surface positioned at the upper window and is movable longitudinally in the inner cavity. A pair of guide grooves 6 is formed along the upper window and guides a roller shaft 5. A distance between a bottom face 7 of the inner cavity and the guide grooves is smaller in a pinching region 7b than in an open region 7a. When the roller is positioned in the pinching region, a tube 11 is closed between the roller and the bottom face, and when the roller is positioned in the open region, the flow path in the tube is opened. The tube clamp further includes a slider 8 that is attached over the roller and is movable together with the roller in the inner cavity. The slider has slider shafts 9 that are provided on each side of the rear end of the slider and engaged with the guide grooves, and bearing notches 10 that are provided on the lower sides of the front end of the slider and fitted to the roller shaft for supporting the roller. The tube clamp can be operated easily with a light force and exert a sufficient force to close the tube.</p> |
