Abstract
打撃工具の打撃に伴う振動を低減して、操作性や作業性を良好とする。ハンマードリル(1)において、ツールホルダ(7)へ回転伝達を行う減速軸(32)と出力軸(9)との間に、出力軸(9)の回転を減速して減速軸(32)へ伝達する中間減速軸(31)を、出力軸(9)よりも前方で出力軸(9)と平行に配置して、減速軸(32)を中間減速軸(31)よりも前方に配置する一方、出力軸(9)が減速軸(32)の第3ギヤ(37)よりも上方へ突出するようにモータ(8)を配置して、モータ(8)をツールホルダ(7)の軸線に近づけた。よって、ハンマードリル(1)の重心が前方且つ上方寄りに位置し、穿孔作業等の際にビット(20)先端を中心としてハンマードリル(1)に発生するモーメントが小さくなる。
