Beschreibung
Zusammenfassung:	A pump housing of a gear pump and a stator of an electric motor are fastened to each other with bolts via a front insulator. Dowel pins are inserted in respective through-holes that are formed in the front insulator at equal intervals in a circumferential direction so as to be located next to insertion holes for the bolts. Respective end portions of each dowel pin are in contact with a bottom face of the pump housing and a pump-side surface of the stator core, and the pump housing and the front insulator are fixed to each other such that a slight gap is formed between the pump housing and the front insulator.
