A diaphragm pump is provided to make a pump structure compact while preventing the leakage of gas due to the failure of a diaphragm. A diaphragm pump has a pump case(45) mounted between a motor case(33) and a pump head(44) for receiving a connecting rod(41) so as to prevent the increase of the pump size. The pump case and the motor case are in a sealed structure and the inside of the pump case is communicated with that of the motor case, so that gas leaked from a pump chamber(46) into the pump case due to the fatigue generated from a diaphragm(42) is prevented from being emitted to the outside of the pump. |
