Figure 15 is the stereoscopic figure of expression with the downward upright state of rear side of dust collector host 301.According to present embodiment, the rear side of dust collector host 301 is erect downwards, open the control of dust case lid 103 that hides disposal box 104, under this state, because screw hole projection 1402 and screw hole projection 1403 are upwards, so, screw 1404 can be inserted in the screw hole projection 1402 and 1403 upwards, and available screwdriver etc. can improve assembling operation efficient thus from dust catcher top one side hold-down screw.In addition, owing to the rear side of dust collector host 301 is erect downwards, so, in assembling operation, the situation that dust catcher moves can not take place, simultaneously, can further improve assembling operation efficient again.

Below, with reference to Figure 16-Figure 18, do an explanation with regard to the outbound course of power line 108a.

Figure 16 is the rear side stereoscopic figure of dust collector host 301, and Figure 17 is the enlarged drawing of major part of the rear side stereoscopic figure of dust collector host 301.Figure 18 shows that the stereoscopic figure of the downward upright state of rear side that makes dust collector host 301.

The power line wrap-up 108 of relevant dust catcher in the present embodiment, as mentioned above, its power line wrap-up axle is positioned on the same direction of fore-and-aft direction of dust collector host 301.For this reason, when power line wrap-up 108 is pulled out power line 108a, be to pull out by the left and right directions of dust collector host 301.That is, the pull-out direction of power line 108a is vertical with the moving direction of dust collector host 301, so, for example with power line 108a when pull out at the rear of dust collector host 301, warpage takes place in power line 108a, causes being difficult to pull out.Therefore, in the present embodiment, be the attaching plug collection portion 1602 that makes the attaching plug 1601 that power line 108a front end is installed, form opening at rear side, upside and cross side with respect to dust collector host 301.Thus, can pull out power line 108a from the either direction of rear, upside and the cross side of dust collector host 301.Again, as shown in figure 17, the top of attaching plug collection portion 1602 covers with handle 132.Thus, hidden attaching plug 1601 makes dust catcher of the present invention have more graceful outward appearance.
