Zusammenfassung:	A hand power tool has at least one safety coupling arranged in a drive train and having at least two coupling elements for transmitting a torque around a rotary axis, at lest one arresting element which is spring loaded and held in a guiding passage for connecting the coupling elements with one another, so that the coupling elements are at least disconnected in response to exceeding of predetermined torque, a spring providing spring-loading of the arresting element and supported in direction of the arresting element by the guiding element, and the guiding element being non rotatably guided relative to an axis extending parallel to the rotary axis by guiding surfaces in the guiding passage.
