In the gear pump, the gear chamber is bored from the bottom side of the housing, and the gear chamber is bored from the bottom side of the housing, and the pair of gears are coupled with each other by the rotation of the motor to pump the fluid in the fluid passage. the opening of the chamber is directed toward the bottom side of the housing;
A seal chamber communicating with the gear chamber is formed in a part of the bottom of the housing located directly below the gear chamber, and the pair of gears are fitted into the gear chamber from the bottom side of the housing through the seal chamber. In addition, a spacer is installed in the seal chamber to block the seal chamber and the gear chamber, and a shaft seal member is press-fitted from the bottom side of the housing through the spacer, and the shaft seal member is used to connect the spacer and the gear chamber. A concentric shaft insertion hole is formed in the spacer and the shaft seal member that supports the gear, and the motor shaft, one end of which is coupled to one of the pair of gears, is inserted into the shaft insertion hole. A gear pump characterized in that the gear pump is inserted through the housing from the bottom side while being sealed with a sealing member. (2) In paragraph 1 of the claims for utility model registration,
A gear pump in which the motor shaft and one of the pair of gears are integrally molded.
