Dust collecting attachment and power tool

A dust collecting attachment removably attachable to a power tool that includes a housing and a spindle, the housing extending in a front-rear direction, the spindle extending along a drive axis extending in an up-down direction perpendicular to the front-rear direction and having a lower end part protruding downward from a front end part of the housing to form a tool mounting part to which a tool accessory is removably attachable, the dust collecting attachment being configured to collect dust generated during a processing operation performed on a workpiece by the power tool, the dust collecting attachment comprising:

• a covering part (i) having a suction hole, (ii) formed such that, in an attached state in which the dust collecting attachment is attached to the power tool, the drive axis passes through the suction hole and the covering part at least partially covers a periphery of the tool mounting part, and (iii) comprising:
• a bottom part provided with the suction hole;
• and
• a peripheral wall (i) surrounding the suction hole, (ii) connected to the bottom part, (iii) extending in the up-down direction, and (iv) including, in the attached state, a first wall, which is located at the front in the front-rear direction and extends along the suction hole, and a pair of second walls connected to the first wall and extending rearward from the first wall;
• a discharging part (i) connected to one of the pair of second walls of the covering part, (ii) extending in a direction that intersects the front-rear direction, and (iii) configured to discharge the dust from the inside of the covering part;
• and
• at least one elastically deformable engagement piece connected to the covering part and having a claw that (i) is configured to engage with the housing at a predetermined position of the housing and (ii) is, in a plan view, located outside of the peripheral wall surrounding the suction hole.
