Abstract: PURPOSE: A manual pump is provided to reduce parts count and erroneous operation by improving the structure of a shaft, a housing cap, a piston and a spring. CONSTITUTION: A portion where a shaft(10) and a housing cap(20) contacts is tapered to form a tapered portion(12). The housing cap has a lower end which is tapered to have a diameter reduced downward. The top of an outer surface of a piston(30) contacting the inner surface of the housing when the shaft is not applied with a downward force, is arranged to contact the tapered portion of the housing cap. The shaft has a sliding portion(13) formed at the end of the tapered portion, and the area where the sliding portion and the tapered portion contacts is connected by a stepped portion(14). A conical support(15) is arranged beneath the shaft, and an inlet opening(16) communicated with an internal passage(11) of the shaft is arranged on the conical support. When the shaft is not applied with a downward force, the periphery of the conical support of the shaft is engaged with the lower end of the inner section of the piston, to thereby prevent the liquid contained within a lower cylinder from flowing into the inlet opening of the shaft. When the shaft is applied with a downward force, the conical support of the shaft is separated from the lower end of the inner section of the piston, the liquid contained in the lower cylinder flows into the inner passage of the shaft through the inlet opening of the shaft.
