る。However, in the case of the former, if the fitting is loose, the dust is removed by wind or vibration for sending the dust, and if the fitting is tight, the dust collecting bag is used to discard the dust. Tight operability was poor when removing. Further, in the latter case, there is no concern that the dust collection nozzle may come off, but there is a gap between the fitting portion of the dust collection nozzle and the dust collection bag, so that there is a problem that the gap is filled with dust or the dust leaks out of the gap. . Further, in the latter case, there is a problem that the mounting position of the dust collecting bag with respect to the dust collecting nozzle is determined. In view of the above-mentioned drawbacks, the present invention facilitates the attachment and detachment of the dust collection bag with respect to the dust collection nozzle, and reliably prevents the dust collection bag from coming off. It is an object of the present invention to provide a dust collecting bag mounting structure for a power tool with a dust collecting device, which prevents dust from leaking out of the device.

Is a fitting portion to which a fitting portion 13b of the attachment member 13 of the dust collecting bag 4 described later is fitted, and has a conical surface whose outer shape gradually increases from the tip toward the inside. The large-diameter portion 3a is fitted so that a fitting portion 13b of a mounting member 13 of the dust collection bag 4 described later is in close contact with the large-diameter portion 3a. On the other hand, the dust collection bag 4 includes a bag 12 and a mounting member 13, and one end 12 a of the bag 12 is fitted into a circumferential groove 13 a of the mounting member 13 to be integrally formed. A retaining claw 14 is formed at the tip inner diameter portion of the mounting member 13 so as to protrude at two positions on the circumference to oppose each other.
Notches 15 are provided on both sides of the claw 14 in the axial direction, thereby making the claw portion 14 flexible. In addition, the claw portion 14
A conical surface is formed in the fitting portion 13b with the dust collecting nozzle 3 at the rear so that the inner diameter gradually decreases toward the inside from the claw portion 14.
