STRIKING TOOL

WIPO Patent Application WO/2013/111460

A1

[Problem] To provide a striking tool that is effective in terms of reducing weight and improving operability. [Solution] A striking tool, having: an electric motor (110) having a rotor (112) and a stator (111); an intermediate shaft (125) which is arranged in parallel with the longitudinal axis of a hammer bit (119) and driven to rotate by the electric motor (110); a swinging ring (129) supported by the intermediate shaft (125), the swinging ring (129) performing a swinging action in the direction of the axial line of the intermediate shaft (125) on the basis of the rotating action of the intermediate shaft (125); and tool driving mechanisms (130, 143, 145) which are linearly actuated in the direction of the longitudinal axis of the hammer bit (119), and caused to linearly drive the hammer bit (119), by the swinging action of the swinging ring (129). The electric motor (110) is configured as an outer rotor-type motor in which the rotor (112) is arranged on the outer side with respect to the stator (111).
