The dust collection case 4 is removed from the main body case 3, and the filter device 25 is also removed from the dust collection case 4 to release dust from the rear opening of the dust collection case 4. At that time, by removing the first suction port body 23 from the suction port body storage recess 24 of the dust collection case 4 and placing your hand in this storage recess 24, it is easy to move only the dust collection case 4 to the place where the dust box is located. can be carried to.

At this time, the first suction port body 2 on the rear surface of the storage recess 24
Since the finger ξ can be firmly hooked onto the support recess IgJ24b of No. 3, there is no chance of the dust collection case 4 falling. In this way, the concave portion 24b serves both as a support portion of the suction port body 23 and as a finger rest portion.

Furthermore, for example, in the dust collection case 4 which is molded by being divided into left and right parts, the suction port storage recess 24 is formed in a shape that cuts out the bulge part 1a and passes through to the left and right, which makes it possible to divide the molding die. This has the effect of making it simple and is also advantageous in terms of molding.

Note that instead of the first changeover switch 56, an interlocking switch 81 shown in FIG. 6 may be provided to close the AC circuit 53 and the DC power supply circuit 54 at the same time.

〔Effect of the invention〕
