    摘要: In a self-compensating dynamic balancer, a main body is installed at a rotating body to restrict internal vibrations due to eccentric mass of the rotating body. The main body has a circular race formed therein around a rotation shaft of the rotating body. A plurality of rigid bodies are disposed in the race to be capable of moving freely and are as many as necessary to occupy at least half of the inner space of the race.

    摘要: The present invention relates to a vibroisolating apparatus for a vacuum cleaner adapted to absorb and inhibit the vibrations generated in a suction motor from being transmitted to a body of the vacuum cleaner to thereby reduce the noise resulting from the vibration to a minimum, and at the same time, to improve the ease of assembling and to decrease manufacturing cost by way of a simplified construction. The vibration generated in the suction motor during operations is absorbed and inhibited at a front side of the motor by a vibroisolating ring which is tightly disposed between a front motor case and the suction motor. The vibration is also absorbed and inhibited at a rear side of the motor by the rear surface packing which is disposed between a rear motor case and the motor. The apparatus thereby reduces generation of noise resulting from the vibration of the suction motor to a minimum and provides for relatively silent operation of the vacuum cleaner.
