Abstract
To provide a reciprocating tool capable of reducing noise by a simple and inexpensive configuration. In a reciprocating tool including a motor that is a rotary drive source, and a reciprocating motion converter that converts the rotation of the motor into the reciprocation of a tip tool, the reciprocating motion converter includes an eccentric rotation member that eccentrically rotates, a reciprocating member that is engaged with the eccentric rotation member and reciprocates, and an elastic member provided between the eccentric rotation member and the reciprocating member. Inside the reciprocating member, an intermediate member is provided, and the elastic member is interposed between the intermediate member and the reciprocating member.
