PROBLEM TO BE SOLVED: To provide a pump for fitting of a liquid container an overall height of which is reduced.SOLUTION: In a pump, an outer peripheral part 18c of an outward flange-like wall part 18 provided on an upper part of a cylinder B is so provided as to be sandwiched between a neck upper surface of a container body and a fitting cap A fitted to a neck outer surface, a lower half part of an operation member E is energized upwards and is so inserted in the cylinder as to be vertically movable, an upper end part of the cylinder is formed as a first standing cylindrical part 17 which extends upwards from an inner end of the outward flange-like part, and an inner ring cylindrical part 30c and an outer ring cylindrical part 30b along both of inner and outer surfaces of the first standing cylindrical part 17 are hung from an annular top plate part 30a, whereby a ring member C is provided. The outward flange-like part projects the outer peripheral part outwards from an inner peripheral part 18a via a second standing cylindrical part 18b, and the outer ring cylindrical part is inserted in a fitting recess 19 formed between the second standing cylindrical part and the first standing cylindrical part. |
