Summary:To restrain inclination of a meshing part with a force applied from a lead screw and a reaction force from a pusher of a syringe.SOLUTION: A syringe pump according to an embodiment includes a lead screw, a meshing portion, a shaft, a slider, and a receiving member. The meshing portion meshes with the lead screw. The shaft is fixed to the meshing portion and slides in a predetermined advancing direction as the lead screw rotates. The slider slides integrally with the shaft and presses the pusher of the syringe. The receiving member sandwiches the meshing portion from both sides in the advancing direction.SELECTED DRAWING: Figure 4 【課題】リードスクリューから加わる力と注射器の押し子からの反力とにより噛み合い部が傾斜することを抑制すること。【解決手段】実施形態に係るシリンジポンプは、リードスクリューと、噛み合い部と、シャフトと、スライダーと、受け部材とを備える。噛み合い部は、リードスクリューと噛み合う。シャフトは、噛み合い部に固定され、リードスクリューの回転に伴い所定の進行方向にスライドする。スライダーは、シャフトと一体でスライドして注射器の押し子を押圧する。受け部材は、噛み合い部を進行方向における両側から挟み込む。【選択図】図４
