摘要 PROBLEM TO BE SOLVED: To provide an effective technique to rationally dispose a dynamic absorber and to enhance vibration suppression, in a working tool equipped with a dynamic absorber. SOLUTION: The dynamic absorber 151 comprises: a dynamic absorber body disposed at an intermediate area between a motion conversion mechanism 113 and a handgrip 105, the dynamic absorber body having accommodation space; a weight accommodated in the accommodation space of the dynamic absorber body so as to be able to move linearly in the long axis direction of a hammer bit 119; and a coil spring located between the front and rear sides of the weight and the dynamic absorber body side, the coil spring extending in the long axis direction of the hammer bit 119 to support the weight in a bullet firing state in the long axis direction, wherein the weight supported in the bullet firing state by the coil spring moves linearly in the long axis direction of the hammer bit 119, enabling to suppress vibrations of the tool body 103 during processing work.
