Motor cover and electric motor equipped with the same
First Claim
1. A motor cover having a resin-made cover main body to be fixed by insert molding in a state where first and second metal parts are spaced from each other, the motor cover covering a case body to be provided to an electric motor, the motor cover comprising:
- a flow-in portion in which a resin material is cast when the cover main body is insert-molded; and
a branch portion which is formed so as to be branched to the flow-in portion and in which the resin material is cast via the flow-in portion, the flow-in portion and the branch portion being provided in the first metal part, wherein a portion of the second metal part is disposed in the branch portion.

Abstract
A heat sink (35) is fixed by insert molding to a resin-made motor cover covering a case body fixed to a motor body. A flow-in portion (51) extending along a straight line and branch portions (62) to (66) formed so as to be branched to the flow-in portion (51) are formed in the heat sink (35), a tip portion of a power-feeding terminal (58) is disposed at the branch portion (62), and the tip portion of the power-feeding terminal (58) is disposed at the branch portion (63). In addition, when a molding resin is cast in the flow-in portion (61) and the branch portions (62) to (66) during the insert molding, these power-feeding terminals (58) and (59) are fixed to the branch portions (62) and (63) and terminal parts (58b) and (59b) are positioned by the branch portions (62) and (63).
