Abstract
An impact tool is provided with a rational structure of connecting a ring-like member and a counter weight. The impact tool has a tool body, a motor, a drive shaft, a ring-like member that is caused to swing in an axial direction of a tool bit by rotation of the drive shaft, a tool driving mechanism, that is connected to the ring-like member and caused to rectilinearly move in the axial direction of the tool bit, and a counter weight that reduces vibration caused in the tool body in the axial direction of the tool bit. The counter weight has a connecting part that comes in contact with an outer edge of the ring-like member in at least one of axial directions of the tool bit, and the counter weight is connected to the ring-like member via the connecting part.
