<p>PROBLEM TO BE SOLVED: To provide an impact tool which can get effect of vibration reduction in both of on-load and no-load conditions without causing upsizing of a main body of the tool.SOLUTION: An impact tool 10 comprises: a tool main body 13 supporting a tip tool 12; an impact force generation unit 45 provided to the tool main body 13 and generating impact force to be applied to the tip tool 12; and a dynamic vibration absorber 59 provided to the tool main body 13 and having an elastic member 58 preventing vibration of the tool main body 13 by the impact force. Settings of natural frequency of the dynamic vibration absorber 59 at the on-load time when the tip tool 12 is pushed to a shaved part (70) differ from those at the no-load time when the tip tool 12 is not pushed to the shaved part.</p> |
