PROBLEM TO BE SOLVED: To provide an excellent liquid jetting pump which is a depressing head type pump to prevent water from entering a vessel to which it is fitted, and also which is not voluminous even when an action member consisting of a depressing head or the like is in a depressed state, and which is formed by accompanying only a change in structure simpler compared with the conventional equipment to eliminate trouble with its production. SOLUTION: The peripheral edge of the upper surface of a fixed suction part A fixed to a vessel body 2 by a loading cylinder 4 is recessed downward through an upward stepped part 12, and between the lower end of the inner surface of a hanging wall 9 hanging to the outer periphery of a depressing head 11 and the upper end of a vertical wall surface 12a of the upward stepped part 12, a cylinder body 13 is hung. In the cylindrical body 13, the upper end of the outer surface thereof and the lower end of the inner surface thereof are engaged with the lower end of the opposite inner surface and with the upper end of the opposite outer surface, respectively so as to make them slidable to each other in the up and down directions of extension and contraction, and is housed between the hanging wall 9 and the hanging wall surface 12a with an action member B being depressed and engaged. |
