The impact tool includes: a plurality of first cam grooves 23b, 23c which are arranged on an outer circumference surface of the spindle 23 and are arranged in a circumference direction around an axis A1 of the spindle 23; a plurality of second cam grooves 24a, 24b which are arranged on an inner circumference surface of the hammer 24 and are arranged in the circumference direction around the axis A1; and a plurality of balls 25 which are held one by one in a plurality of pairs of cam grooves, wherein either one of the plurality of cam grooves 23b, 23c and either one of the plurality of second cam grooves 24a, 24b make a pair. The plurality of first cam grooves 23b, 23c are arranged in different positions in a direction along the axis A1.
【課題】ハンマの打撃力を上昇させることの可能な打撃工具を提供する。【解決手段】スピンドル２３と、スピンドル２３の外周面に取り付けられ、かつ、スピンドル２３の回転力を回転方向の打撃力に変換するハンマ２４と、を有する打撃工具であって、スピンドル２３の外周面に設けられ、かつ、スピンドル２３の軸線Ａ１を中心とする円周方向に配置された複数の第１カム溝２３ｂ，２３ｃと、ハンマ２４の内周面に設けられ、かつ、軸線Ａ１を中心とする円周方向に配置された複数の第２カム溝２４ａ，２４ｂと、複数の第１カム溝２３ｂ，２３ｃのいずれか１つと、複数の第２カム溝２４ａ，２４ｂのいずれか１つとを１組として、複数組のカム溝に１個ずつ保持された複数のボール２５と、を有し、複数の第１カム溝２３ｂ，２３ｃは、軸線Ａ１に沿った方向で異なる位置に配置されている。【選択図】図１ |
