Abstract
A pump case of an electric pump is constructed by coupling a first pressed member formed with a cylindrical part for holding a first rolling ball bearing rotatably supporting a rotary shaft, and a second pressed member formed with a recess for receiving an inner rotor provided at a tip end of the rotary shaft to each other. Because the first pressed member and the second pressed member are formed by deep-drawing work, it is possible to achieve simplification of the structure and reduction of the cost, as compared with the pump case which has been produced from an aluminum die casting or the like, as in the related art.
