PROBLEM TO BE SOLVED: To provide a tube pump in which lubricating action is stably performed for a long period even if the rotational speed is high. SOLUTION: An ear piece 11 projecting in the axial direction of a pressure member 4 is formed, in a ring shape, at the outer peripheral edge of the pressure member 4 made of an elastic material. The ear piece 11 is brought into slidable contact with the side walls 2b, 2c of a cylindrical chamber 2. Therefore, even if a tube 3 is suddenly pressed, a lubricant 8 passing through the slidable contact part between the ear piece 11 and the side walls 2b, 2c is less and the lubricant 8 remains on and around the tube. Consequently, the lubricating action can be maintained for a long period even if the rotational speed of the pump is high. COPYRIGHT: (C)2007,JPO&INPIT
