ABSTRACT:
In a hand power tool for surface machining, with a vibrating plate, which is suspended on a housing by vibrating elements, and with an electromotively driven eccentric drive, which is contained in the housing and sets the vibrating plate into an orbital oscillating motion, in order to produce a housing that is rather flat and short, which can be manually controlled in the same way as a grasping block, the coupling point is situated between the eccentric drive and the vibrating plate, close to the front edge of the vibrating plate, while the elastic vibrating elements engage the vibrating plate close to the opposite edge of the vibrating plate. The vibrating plate is affixed to the housing in the region between the coupling point and the engagement points of the vibrating elements by means of a movement transmission mechanism, which is flexurally flexible at one end and which converts the orbital motion of the vibrating plate, which is generated at the coupling point, into a reverse orbital motion at the engagement points (FIG.2).
