Abstract: A portable power tool is disclosed. The tool has a tool holder in which a tool can be moveably inserted on a working axis in a striking direction. A percussion mechanism has a striker coupled via a pneumatic chamber to an exciter moved periodically along the working axis and an intermediate striker arranged in the striking direction downstream from striker. The intermediate striker is guided in a slide bearing with a tolerance coaxially to the working axis. The intermediate striker has a ring-shaped bead. A hollow-cylindrical backstop is arranged in the striking direction upstream from the bead. The backstop is moveably guided on a sliding surface with radial play along working axis. The radial play is at least three times as large as a tolerance of the guide of the intermediate striker in the slide bearing.
