Abstract
It is an object of the invention to provide a technique for adapting to the length of a tool bit mounted to a power tool when tool bits of different lengths are selectively used by replacement to perform an operation, in a dust collecting device for collecting dust generated by operation of the power tool. A dust collecting deviceis attached to a power tooland collects dust generated by operation. The dust collecting deviceincludes a dust collecting part that covers a tool bitover a predetermined range in the axial direction and collects dust generated by operation. The dust collecting part is formed in one of a first form and a second form which is arbitrarily selected. In the first form, the dust collecting part is formed by a dust collecting part componentwhich has a tool bit covering parthaving a predetermined inside diameter and a fitting partconnected to the tool bit covering part, while, in the second form, the dust collecting part is formed by connecting a plurality of the dust collecting part componentsvia the fitting partin the axial direction.
