When the injection button 500 is pressed, the state of the first pressing step is reached. In the first pressing step, the end of the direct connection stem 70 is brought into contact with the end of the undiluted solution switch 60. At this time, the sealing ring 102 that surrounds the direct-connection stem 70 maintains a state of being in close contact with the undiluted solution transfer path portion 11, and the undiluted solution switch 60 is in close contact with the hermetic portion 103 The switch guide 14 does not move. Also, the undiluted solution delivery path portion 11 is kept blocked by the switch guide 14.
