Abstract
A rotary hammer has a hammer body with an electric motor section which comprises a receiving section for receiving transmission mechanisms in a frame which serves as a shell barrel. A driving electric motor is installed in the shell barrel. The body also has a vibration and transmission mechanism section in which the transmission mechanisms including the motion conversion transmission mechanism and the vibrating mechanism are held by a bracket removably connected to the frame. In addition, the hammer body has a tool holding section in which the tool holding member for concomitantly rotatably holding the tool is rotatably supported by a bracket removably connected to the frame. The three sections are so arranged that they can be assembled and disassembled individually as separate component units.
