Beschreibung
Zusammenfassung:	A pump housing (12) of a gear pump (3) and a stator (4) of an electric motor (2) are fastened to each other with bolts (14) via a front insulator (13). Dowel pins (15) are inserted in respective through-holes that are formed in the front insulator (13) at equal intervals in a circumferential direction so as to be located next to insertion holes for the bolts (14). Respective end portions of each dowel pin (15) are in contact with a bottom face of the pump housing (12) and a pump-side surface of the stator core (8), and the pump housing (12) and the front insulator (13) are fixed to each other such that a slight gap is formed between the pump housing (12) and the front insulator (13).
