Abstract
A hand-held power tool has a housing in which a drive motor for driving a percussion mechanism is arranged. The percussion mechanism has a percussion piston arranged in a hammer tube for displacement along an associated percussion axis, via a connecting rod. The percussion mechanism is assigned an eccentric for driving the connecting rod in rotation. A reduction-gear mechanism driven by the drive motor has a first spur gear arranged along the percussion axis between the drive motor and the eccentric. The eccentric is arranged on a second spur gear. The first spur gear meshes with teeth of the second spur gear. At least some of the teeth of the second spur gear are positioned perpendicularly to the percussion axis, between the percussion axis and a plane arranged parallel to the percussion axis. A bearing element of the eccentric arranged towards the percussion axis is arranged in the plane.
