Abstract: A microcomputer operates as a positioning part positions a rotor at a control start position, which is a position of the rotor relative to a stator to be able to start controlling driving of a brushless motor, by supplying a current to a winding set a number of times “n” (n is an integer equal to two or more) before starting to control driving of the brushless motor. The microcomputer, operating as the positioning part, controls electric power supplied to the winding set so that the rotor rotates in the same direction at each of “n” times of power supply to the winding set, that is, at each of “n−1” times of switchovers of power supply to the winding set.
