Abstract

A chemical liquid injection device has a casing (113) having a depression (114) for holding a cylinder (210) and also has a piston drive mechanism (130) having a piston pressing section for pressing a piston flange of the piston (220). The piston drive mechanism (130) is controlled so that, when the piston pressing section is in those last sections of its strokes in which it reaches the ends of its movements, its movement speed is lower than that in other sections. In the above, the last sections are both the last section of a stroke of the piston pressing section from its initial position until it is in contact with the piston flange and the last section of a stroke of the piston pressing section from its advanced position until it returns to the initial position.
