Abstract
It is an object of the invention to provide an effective technique for enhancing the effect of reducing vibration of a grip of a reciprocating power tool. According to the present invention, a representative reciprocating power tool may comprise a tool bit, a tool body and a grip. The grip is connected to the tool body via an elastic element and a vibration damping part. The elastic element is resiliently disposed between the tool body and the grip and serves to absorb vibration transmitted from the tool body to the grip during operation. The vibration damping part is disposed between the tool body and the grip and serves to damp and/or attenuate the vibration. According to the invention, the spring constant of the elastic element can be made smaller due to vibration damping part.
