摘要： A technique for allowing a user to operate an operating member disposed in a front end region of a power tool in the state in which a dust collecting attachment designed to be attached to the front end region of the power tool is left attached to the power tool. The dust collecting attachment is used on a power tool having an operating member for removal and/or bit angle setting of a tool bit coupled to a front end region of a tool body. The dust collecting attachment has a dust collecting member which can be attached to the front end region of the tool body. The dust collecting member has an opening formed in a region which faces the operating member in the state in which the dust collecting member is attached to the tool body, and the operating member can be operated by user's finger through the opening.

摘要： A dust collecting device is provided which is capable of preventing static charge while rationally collecting dust generated during operation. A dust collecting device is removably attached to a power tool and can be carried together with the power tool, and collects dust generated when a predetermined operation is performed on a workpiece by driving a tool bit coupled to the power tool. Further, the dust collecting device has a dust suction region that sucks dust generated during operation in response to the operation of the tool bit, a dust transfer region that transfers the dust sucked in the dust suction region, and a dust storage region that communicates with the dust transfer region and stores the dust. Furthermore, the dust collecting device has a grounding member through which static charge on the dust is dissipated.

摘要： A hammer drill is provided with a connector equipped with a female terminal, movably between a connection position where the female terminal is located inside a plug-in port and a non-connection position where the female terminal is in retreat from inside the plug-in port. The hammer drill is also provided with a torsion spring that urges the connector toward the non-connection position. The connector is provided with a shutter portion that is located inside the plug-in port to close the plug-in port at the non-connection position and is in retreat from inside the plug-in port at the connection position. A dust collecting device is provided with a press rail that comes into abutment on the connector to move the connector to the connection position against the urging of the torsion spring as the dust collecting device is mounted.
