To provide a trigger-type liquid injector which reduces necessity of a sliding member in a pump, and thus can improve reliability and reduce the number of components.SOLUTION: A trigger-type liquid injector 1 includes: an injector main body 3 which is mounted on a mouth part 2a of a container 2 for storing a liquid; a trigger 4 which is supported by the injector main body 3; and a pump 7 which press-feeds the liquid stored in the container 2 to an injection port 6 arranged on the injector main body 3 by changing a volume of a pump chamber 5 by operation of the trigger 4, and injects the liquid from the injection port 6. In the trigger-type liquid injector 1, the pump 7 includes an elastic member 14 for partitioning the pump chamber 5 on an inner side by having a cylindrical outer peripheral wall 22 and a closing part 23 which closes one end 22a of the outer peripheral wall 22 in an axial direction. The closing part 23 includes a protrusion part 28 which protrudes to the other end 22b of the outer peripheral wall 22 in the axial direction from the one end 22a of the outer peripheral wall 22 in the axial direction on an inner side than the outer peripheral wall 22 in a radial direction.SELECTED DRAWING: Figure 1
