Abstract (en)

[origin: WO2007090478A1] The invention is based on a portable power tool, in particular a hammer drill and/or a rotary demolition hammer, comprising a motor (10a, 10b, 10c) and a motor shaft (12a, 12b, 12c), comprising a percussion mechanism unit (14a, 14b, 14c) which can be driven by the motor (10a, 10b, 10c) for achieving an impulse in the direction of a percussion axis (16a, 16b, 16c) and which has an axial drive unit (18a, 18b, 18c) having an output means (20a, 20b, 20c), and comprising a transmission unit (22a, 22b, 22c) which is provided for transmitting a drive force 15 from the axial drive unit (18a, 18b, 18c) to a piston unit (24a, 24b, 24c). It is proposed that, in the region of the transmission unit (22a, 22b, 22c), the motor shaft (12a, 12b, 12c), as viewed in the longitudinal direction 20 of the percussion axis (16a, 16b, 16c), be directed laterally past at least one part of the transmission unit (22a, 22b, 22c).
