Abstract
A male terminal is formed on a dust collecting device so as to protrude therefrom, while a plug-in port into which the male terminal can be inserted, and a female terminal that is located inside the plug-in port and can be electrically connected to the male terminal, are provided in a hammer drill. When the dust collecting device is joined to the hammer drill and the male terminal is electrically connected to the female terminal, a driving source is supplied from a battery pack to the dust collecting device.
