Claim Text:
1. A hand power tool, comprising: a drive mechanism, a mechanism housing defining (i) a chamber in which the drive mechanism is disposed and (ii) an opening leading into the chamber, at least one vibration absorber device which has at least one absorber spring, an absorber mass, and a first holding part supporting an outermost axial end of the absorber mass, the at least one absorber spring defining a spring direction and the first holding part engaging the absorber mass such that the first holding part, the absorber spring, and the absorber mass are at least partially disposed on at least one same plane that is aligned normal to the spring direction, and a housing cover having (i) an external surface facing away from the opening, (ii) an internal surface facing towards the opening, and (iii) at least one integrally-formed fastening mechanism extending from the internal surface and defining at least one planar fastening surface arranged normal to the spring direction, wherein the absorber spring is configured to press the vibration absorber device into the planar fastening surface such that the vibration absorber device is completely retained on the housing cover by contact between the vibration absorber device and the planar fastening surface, and wherein the housing cover and the retained vibration absorber device constitute a preassembled structural unit that (i) extends through the opening to the chamber and closes the chamber when the preassembled structural unit is connected to the mechanism housing and (ii) is spaced from and moveable relative to the hand power tool when the preassembled structural unit is disconnected from the mechanism housing.
