摘要： To prevent damage to a tube in a roller pump which pumps a fluid contained in the tube by squeezing it against an inner wall surface of a housing with a roller, so that the tube can be used continuously for a long time. A depression which a part of the tube enters when squeezed with the roller is formed on at least one of a roller surface of the roller and the inner wall surface of the housing. This alleviates a load on the tube, thereby preventing damage to the tube. Alternatively, the roller may include a plurality of disc rollers that are separately rotatable. This reduces differences in frictional force acting upon the tube when squeezed by the roller, thereby preventing damage to the tube. According to these constructions, the tube can be used continuously for a long time.
