<P>PROBLEM TO BE SOLVED: To effectively use a mounting space of a circuit board of an ECU by reducing a space required for mounting a relay in an electric power steering device. <P>SOLUTION: Stationary contact points 712a, 712b, 722a, 722b are formed on wiring members 510, 610, 520, 620 constituting a U-phase and V-phase current supply path to a brushless motor. A U-phase movable contact point 710 capable of bridging the stationary contact points 712a and 712b for a U-phase and a V-phase movable contact point 720 capable of bridging the stationary contact points 722a and 722b for a V-phase are movably integrated with each other. A solenoid 750 as means for displacing the U-phase and V-phase movable contact points 710, 720 is embedded in a heat sink 501 in the ECU, and the U-phase and V-phase current supply path can be opened and closed by one solenoid 750. <P>COPYRIGHT: (C)2008,JPO&INPIT |
