PROBLEM TO BE SOLVED: To ensure the balance of a total receiving plate by forming the receiving plate with a first receiving plate member and a second receiving plate member, and backing the second receiving plate member in a state that the press-sealing state of the infusion tube is kept when a first finger and a N-th finger are moved to the press-sealing position. SOLUTION: A back plate member 131 (second receiving plate member) comprising a first finger and a fourth finger opposite to each other, is set on a back plate base 132 (first receiving plate member) from the back, and a hole part 132a from which only a projecting part 131a of the back plate member 131 is exposed, is integrally formed. The back plate base 132 and the back plate member 131 are supported in a state that they are respectively energized by a high compression coil spring 136 and a low compression coil spring 135. The projecting part 131a of the back plate member 131 is backed to be prevented from damaged when the over load is applied when the infusion tube 2 is pressed in excess for some reason. |
