PROBLEM TO BE SOLVED: To provide a structure for mitigating excessive pressing pressure to be applied to a tube when the tube is to be excessively pressed, while preventing swing of a rotary shaft of an eccentric member circulating a position of pressing the tube by rotation in an infusion pump cassette and the like for delivering a liquid through a tube.SOLUTION: A cylindrical body 24 is configured to move or be elastically deformed for mitigating excessive pressing pressure to be applied to a tube 2 when an eccentric member 40 presses the tube 2 by an annular part 30, and cause a housing (a trunk part 21, a lid part 22, and a bottom part 23) out of a body 20 to bear a bearing of a rotary shaft 41. This configuration can prevent swing of the rotary shaft 41 of the eccentric member 40 and mitigate the excessive pressing pressure to be applied to the tube 2. |
