PROBLEM TO BE SOLVED: To provide a more rational technique capable of reducing unstable driving elements of an impact piece and suppressing vibration.SOLUTION: A working tool 100 is configured so that: a first compensation mechanism 180 moves an oscillation mechanism 121 from an oscillation mechanism reference position 1211 toward an oscillation mechanism movement position 1212, and moves a cylinder 127 toward a second side 100a2, for enlarging a volume of an air chamber 128; and a second compensation mechanism 190 moves a meson 145 from a meson reference position 1451 toward a meson movement position 1451, and moves an impact piece 143 toward the second side 100a2, for compensating the volume of the air chamber 128.SELECTED DRAWING: Figure 11 |
