<P>PROBLEM TO BE SOLVED: To prevent a connecting part and a circuit board from being broken by preventing the generation of stress at the connecting part between a connector pin connected to the outside and the circuit board, in a bus bar of an electric motor. <P>SOLUTION: The bus bar 50 of the electric motor comprises: a substantially annular resin body 51 having a wiring plate inside; and the circuit board 52 arranged on the resin body 51, and a plurality of the connecter pins 513 that are substantially J-shaped metal members are arranged at a part of the resin body 51. In the bus bar 50, a part between both ends 513a, 513b of each connector pin 513 is resin-molded so as to be positioned in the resin body 51 by insert molding. By this, a force acting on the connector pin 513 when an external connector 711 is attached and detached is absorbed in the resin body 51, and the stress is prevented from being generated at the connecting part between the connector pin 513 and the circuit board 52, thus preventing the connecting part and the circuit board 52 from being broken. <P>COPYRIGHT: (C)2007,JPO&INPIT |
