    • A motor driver (1A) is provided with a circuit board (100) on which a feeder circuit is formed, a supporting member (8) fixed to the substrate (100), and a small-sized motor (2A) detachably attached to the member (8). The motor (2A) is a DC vibrating motor and is constituted of a casing (3), a stator (4) and a rotor (5) both housed in the casing (3), a plus terminal (6) and a minus terminal (7) both for supplying electric power to the rotor (5), and a weight (eccentric body) (25) fixed to the end of the rotating shaft (53) of the rotor (5). A notched section (321) and a recessed section (335) are formed in the motor (2A) as rotation preventing means which prevents the rotation of the whole motor (2A) relative to the supporting member (8) when the motor (2A) is driven. An engaging piece (83) which is engaged with the notched section (321) and an engaging piece (85) which is engaged with the recessed section (335) are provided on the supporting member (8).
    • 电动机驱动器(1A)具有形成有馈电电路的电路板(100),固定在基板(100)上的支撑部件(8)和可拆卸地安装在基板上的小型马达(2A) 会员(8)。 电动机(2A)是直流振动电动机,由容纳在壳体(3)内的外壳(3),定子(4)和转子(5)构成,正极端子(6)和负极端子 (7),以及固定在转子(5)的旋转轴(53)的端部的重物(偏心体)(25)。 在电动机(2A)中,作为防止整个电动机(2A)相对于支撑部件(8)旋转的防旋转装置,在电动机(2A)中形成有切口部(321)和凹部(335) 被驱动。 与所述切口部分(321)接合的接合件(83)和与所述凹部(335)接合的接合件(85)设置在所述支撑件(8)上。
