摘要： An electric motor comprises a rotor constructed by a disk-shaped multi-pole magnet secured to a rotary shaft and rotatably supported, and a stator constructed by a pair of star-shaped flat drive coils arranged adjacent and opposing to the disk-shaped multi-pole magnet. Sinusoidal wave currents, the phase angles of which differ by 90.degree. from each other, are supplied to the pair of drive coils to drive the magnet. A speed detection coil having a plurality of power generating strands is arranged in a field of the magnet and a field of the drive coils to produce a signal having a frequency corresponding to a rotational speed of the magnet. A cancellation coil is also arranged in the field of the drive coils to produce a voltage which varies with the change of the drive coils, which voltage is added to an output signal from the speed detection coil to cancel out a signal developed across the speed detection coil by the change of the drive field so that a speed detection signal of a high S/N ratio is derived to enable the control of the rotation of the electric motor.

摘要： A turning direction indicator device includes an actuator that rotates by an operation of the operating lever, a cam body that shifts in a rearward direction approaching a cancel cam. The cam body is rotatable about a rotation axis, and shifts in the rearward direction when the actuator rotates. The cam body includes a rear wall surface opposite to the cancel cam. The rear wall surface has two end parts symmetrical to each other with respect to the longitudinal axis. A spring elastically contacts the end parts to urge the cam body in the rearward direction. The spring also urges the cam body in a rotating direction about the rotation axis when the longitudinal axis of the cam body rotates. The turning direction indicator device suppresses a hitting noise produced by the cam body and a release element with such a simple structure, and operates reliably.
