Abstract: In a power hand tool, especially a screwdriver, with a motor, a planet gear and a rotary impulse generator, a spring mechanism is provided to damp vibrations of the housing caused by the rotary impulse generator. To improve the damping with a simple design, one end of a compression spring is supported on a ring, which in turn is guided at a coil which is parallel to the axis, on the one hand, and is guided displaceably in parallel to the axis between a part rigidly connected to the housing and a part exposed to the rotary impact, on the other hand. The other end of the compression spring is supported on a part rigidly connected to the housing.
