PROBLEM TO BE SOLVED: To provide a pump which is easy in a change of colors and shapes of members constituting the pump, in particular, a discharge head, an attachment cap or the like, and in which a variety of forms can be easily and selectively formed.SOLUTION: A pump comprises a cylinder B which is attached and fixed to a vessel body by an attachment cap A, and hung into the vessel body, and an operation member C which is vertically movably attached to the cylinder B in an upwardly-energized state. The pump scoops up and discharges liquid in the vessel body by the vertical movement of the operation member C. A discharge head C4 constituting an upper end of the operation member C comprises a flow passage p which reaches a discharge port h from the inside of a stem C1, and is constituted of an adapter C4a fit to the upper end of the stem C1, and a cover body C4b fit to the adapter C4a. The whole of the pump is constituted of: a pump base body X which is modularized by pushing down and locking the operation member C except for the cover body C4b to the cylinder B; and the attachment cap A and the cover body C4b assembled into the pump base body X. |
