Abstract
The invention relates to an electric hand tool comprising a housing, a reciprocating carrier for an operating member drivable by means of an electric motor placed in the housing, wherein the carrier is guided by at least two guide members fixed in the housing, wherein the guide members each comprise two guides placed on either side of the carrier, wherein one of the guides is fixedly attached and the other guide is provided with means for urging the guide against the carrier. The occurrence of play, wear, noise nuisance and vibrations is thus avoided. According to a preferred embodiment, both guides forming part of a guide member are formed by guide rollers received in a frame and the frame is fixedly mounted by means of a shaft extending through one of the guide wheels and a spring is placed between the housing and the frame such that the spring urges the other guide wheel into contact with the carrier.
