ABSTRACT:
In a vibrating tool, a body housing and a handle are displaceably interconnected and a large range of vibrations can be effectively absorbed. A vibrating tool is composed of a body housing and a handle. A projection is provided at the rear end of the body housing. By engaging a stop on the handle with a flange on the projection, the handle is positively interconnected with the housing with a clearance therebetween. A rubber ring is located in the clearance between the handle and the body housing. A radially inwardly opening groove is provided in the rubber ring, so that the ring is easily deformed when the handle and the body housing are displaced relative to each other. Since the handle and the body housing are displaceably interconnected with each other and the rubber ring interposed between the handle and the body housing is easily deformed, large amplitude vibrations can be absorbed. The inwardly opening groove is sealed by the outer periphery of the projection of the housing, thereby providing an air cushion effect for absorbing high frequency vibrations.
