摘要： It is an object of the invention to provide a useful technique for reducing vibration of a handgrip and improving the cutting efficiency while achieving weight reduction of a reciprocating power tool. According to the invention, a representative reciprocating power tool is provided to comprise a body, a tool bit, an actuating mechanism, a handgrip. The handgrip and the body can rotate with respect to each other via a pivot in a direction crossing the direction of reciprocating linear motion of the tool bit. An elastic element is disposed between the handgrip and the body and serves to absorb vibration transmitted from the body to the handgrip by elastically receiving the relative rotation of the handgrip and the body. According to the invention, vibration in the handgrip can be reduced and the cutting efficiency can be improved without complicating the construction.
