    摘要: To prevent the adhesion or penetration of iron filings or other magnetically permeable material, thereby avoiding a short-circuit of the magnetic circuit and ensuring an accurate output signal, a membrane comprised of a non-magnetic material covers the bottom of a casing facing a rotor, and a protuberance of a length at least equal to the maximum air gap between the membrane and the rotor is integrally molded to a portion of the membrane.

    摘要: A vehicle door mirror assembly has a stationary base unit, a door mirror unit mounted on the base unit so that the mirror unit is swingable about a vertical swing axis, an ultrasonic motor for supplying power to swing the mirror unit, a fixed gear fixed to the base unit, and a speed reducing gear set. The ultrasonic motor and the gear reducing gear set are both mounted on the mirror unit. The speed reducing gear set has a driving gear driven by the motor, an intermediate gear engaged with, and driven by, the driving gear, and a driven gear which is connected with the intermediate gear by a joint shaft and which is engaged with the fixed gear. When the motor drives the driving gear, the driven gear is driven by the driving gear at a reduced speed, and moves around the fixed gear to swing the mirror unit about the axis of the fixed gear. This door mirror assembly is advantageous in compactness, durability and efficiency.
