Claims

[Scope of utility model registration request]

It consists of an electric motor and a rotary pump mechanism attached to the protruding side end of the motor shaft of the electric motor, and the rotary pump mechanism is configured to suck in fluid from one side and discharge it from the other side by driving a rotating member. The rotating member of the rotary pump mechanism is provided with an engagement hole that can be rotatably fitted into the motor shaft, and the motor shaft having a rotor is supported by a bearing provided in the housing, and one end side of the motor shaft is supported by a bearing provided in the housing. The housing protrudes outward from the housing, and the housing on the motor shaft protruding side also serves as the drive side cover of the rotary pump mechanism, and the protruding end of the motor shaft is fitted into the rotating member retaining hole of the rotary pump mechanism so as to be rotatable. A fluid pressure pump with an electric motor.
