Abstract
A hammer drill includes a dust collector engaged with a housing by sliding. An engagement protrusion, which can engage and disengage with a rear engagement recessed portion provided on a guide groove of the housing, is provided at a position where the dust collector engages with the housing and biased in the direction of engagement with the rear engagement recessed portion. A front engagement recessed portion is also provided on the guide groove, and can engage with the engagement protrusion at a slide position of the dust collector in front of the engagement position. By engaging the engagement protrusion with the front engagement recessed portion, the dust collector can be fixed to the housing even at the slide position.
