Abstract

An impact tool comprises a motor, a swinging member that is driven by the motor and swings in an axial direction of the tool bit, a striking mechanism that is driven in the axial direction of the tool bit by the swinging motion of the swinging member, a connecting part that connects the swinging member and the striking mechanism, a housing member that houses at least the connecting part in an internal space, and a counter weight that is disposed within the internal space of the housing member and reduces vibration caused when the tool bit is driven.
