ABSTRACT:
A vibroisolating handle joint structure for a power tool such as a disc grinder has a vibratable power tool unit, a tubular handle holder fastened to the power tool unit and having first axial surfaces, a grip handle having on one end thereof a larger-diameter cup disposed radially around the handle holder and having second axial surfaces extending in substantially axially confronting relation to the first axial surfaces, and elastic members disposed between and joined to the first and second axial surfaces. The power tool unit and the handle are thus interconnected by the elastic members in a vibroisolating manner without using metallic plates. Even when some of the elastic members are torn apart, the power tool unit and the handle are prevented from being separated from each other by the first and second axial surfaces which are engageable with each other.
