<P>PROBLEM TO BE SOLVED: To restrict a movement of electronic parts even when the electronic parts fall off from a fixed position in an electric motor which assists driving operation of a vehicle. <P>SOLUTION: This stator portion 3a of the motor has a bus bar 51 attached to an armature 3, and a substrate 52 attached to the bus bar 51. A first recessed portion 516 facing a portion of the circuit board 52 is formed at a surface of the bus bar 51 on the side of the circuit board 52. All chip parts 524 mounted on a surface on the circuit board 52 are mounted in advance in a recessed portion facing range 523 on the bus bar 51 side of the circuit board 52. By attaching the substrate 52 to the bus bar 51, the chip parts 524 on the circuit board 52 are covered with the first recessed portion 516, therefore the movement in the chip parts 524 can be restricted within the first recessed portion 516 even when the chip parts 524 fall off from the fixed position on the circuit board 52. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
