PROBLEM TO BE SOLVED: To automatically align the center of a pusher to the center of an outer cylinder to increase flexibility in use of a syringe pump and to improve operability when various kind of syringes with different sizes of outer cylinders and pushers, by equipping a guide mechanism to support a pusher clamp mechanism main body reciprocal against a slider. SOLUTION: A guide mechanism is constituted of a sliding groove 82 and a guide plate 52 at a connection part between a slider 5 and a pusher clamp mechanism 8, and the pusher clamp mechanism 8 is supported reciprocally movable against the slider 5 in a plane parallel to the center line of a V-shaped receiver and vertical to the syringe axis. A stopper of the guide plate 52 is formed by blocking one end of the sliding groove 82, and an engaging means is equipped in between the pusher clamp mechanism 8 and the slider 5 so that the guide plate 52 is not extracted from the other end of the sliding groove. |
