Abstract
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.
