At the rear of the first cam(), a second cam() having cam gears(. . . ) and further having cam gears(. . . ) at its outer circumference is externally provided to the anvil() so as to be rotatable. At the backward position of the anvil(), the cam gears() contacts with each other. On the other hand, in the cylindrical portion() of the hammer case(), an engaging pin() capable of engaging with an engaging gear() of the second cam() is provided. The engaging pin() can change its location by the rotative operation of a mode-change ring(), whereby a percussion mode and a non-percussion mode is selected.
