Each of reinforcing members (22) is arranged on both end faces of the laminated core (14) in the axial direction, respectively in such a manner that each of them contacts each multihole wall (28) and the through holes (16) communicate with the holes (32). In this state, the laminated core (14) and the reinforcing members (22) are fixedly supported by a jig (34), and then, arranged in a mold (36). When casting, a molten metal is poured into a continuous cavity including the annular spaces in the reinforcing members (22), the holes (32) of the multihole wall (28), and the through holes (16) of the laminated core (14) through the central opening (31) of the end wall (30) of one reinforcing member (22a) arranged on the pouring gate (58) side. At the same time, the gas in the cavity is exhausted through the central opening of the end wall (30) of the other reinforcing member (22b).
