PROBLEM TO BE SOLVED: To provide a diaphragm pump capable of being easily assembled.SOLUTION: A discharging valve 54 includes a discharging valve seat 51 formed in a columnar shape, and a discharging valve element 43 in a conical cylinder shape made of a material softer than the discharging valve seat 51. The discharging valve 54 has a configuration in which the valve seat is inserted from one opening of the discharging valve element 43 and an end of the other opening having a diameter smaller than the one opening is abutted to a peripheral surface of the discharging valve seat 51, and therefore, the discharging valve element 43 hardly deflects when the discharging valve seat 51 is inserted into the discharging valve element 43 so as to be assembled. As a result, a diaphragm pump can be easily assembled. |
