Abstract
It is an object of the invention to provide a technique to further increase protection performance for a battery pack of power tool. A representative power tool may include a tool body to which a tool bit is coupled to perform a predetermined operation, a driving motor that is disposed within the tool body, a battery pack that supplies driving current to the driving motor, the battery pack being removably mounted to the tool body and placed on the outside of the tool body in an exposed state, and a protector that is removably mounted to the tool body to protect the battery pack. The protector may include a battery pack protection area that protects the battery pack mounted to the tool body when the protector is mounted to the tool body. The battery pack protection area is dosed on at least part of the outer surface of the battery pack with a clearance and prevents transmission of external force upon the battery pack protection area to the battery pack.
