When the tube 5 is inserted through 6c and the operation piece 46b is not operated while being gripped, the internal space of the tube 5 is pushed to the fully closed state by the locking piece 46a of the operation member 46 which is moved by the elastic force of the return spring 44. The tube 5 is crushed, and the crushing of the tube 5 interrupts the left and right communication.

量化とコンパクト化並びに低コスト化が図れる。As described above, according to the diluting liquid injecting apparatus of the present invention, the fine flow rate of the diluting liquid can be easily adjusted as compared with the conventional manual type.
Accurate amounts can be injected for repeated dilutions. In addition, since the injection of the diluent is performed by free flow, it is possible to omit many parts such as a flow pump and a microcomputer as compared with the conventional automatic type, and to reduce the weight, size, and cost of the entire apparatus. Can be achieved.
