A puncture device (A) can carry out a puncture tool retreat operation for retreating a puncture tool holder (2) to locate a puncture tool (9) at a predetermined retreat position and a puncture tool release operation for pushing out the puncture tool (9) forward of the holder (2) after the completion of puncture by moving a control member (3) in a predetermined direction from a waiting position. After the operations of retreating and releasing the puncture tool take place, the control member (3) restores to the waiting position by an action of a returning member (7) in either case. Thus the puncture device (A) is convenient to use. |
