The reference numeral 26 is as if the flexible flat plate, which is bent 90 degrees while being in close contact with the suction seal mounting plate 22, is hollowed out in an annular shape, and the intermediate portion 25 is formed in the annular lip portion 24. It is in the form of a film that is connected to the entire peripheral portion of the inner portion and the entire peripheral portion of the inner portion of the annular fixing portion 26. Further, the lip portion 24 extends from the inside of the decompression region 02 toward the outside along the surface to reach the peripheral portion 2 of the main portion 2.

と無く該凹凸を容易に乗越えることができる。Next, the operation of the above-mentioned device will be summarized and described. When the vacuum generating means (not shown) is activated,
A fluid such as the atmosphere in the decompression region 02 is discharged to the outside through a suction hose (not shown), and thus the decompression region 02 is decompressed as required. When the decompression region 02 is decompressed in this way, the fluid pressure acting on the decompression container due to the fluid pressure difference between the inside and outside of the decompression region 02 is transmitted to the wall surface 03 and the floor surface 04 via the wheels 12. Thus, the pressure of the surrounding fluid causes the decompression container of the present invention to move to the wall surface 0.
3 and the floor 04. Further, when the wheels 12 are driven to rotate in such an attracted state, the wheels 12
By this action, the decompression container moves along the portion where the wall surface 03 and the floor surface 04 intersect. Further, in the suction movement state, the wall surface 03 is moved from the blast nozzle 31.
When the abrasive material is jetted together with the compressed air toward the floor surface 04, the surface surrounded by the decompression container is continuously blast-cleaned, and the jetted abrasive material is a vacuum generating means (Fig. By the action of (not shown), it is discharged to the outside through the suction hose (not shown) together with the atmosphere in the decompression region 02. At this time, since the polishing agent is sprayed in the reduced pressure area 02, the polishing agent and dust are not scattered outside the reduced pressure container. The decompression container is attached to the wall surface 03.
And, when it is adsorbed to the floor surface 04, the protrusion 244 of the lip portion 24 of the adsorption seal 23 is strongly brought into contact with the wall surface 03 and the floor surface 04 by the pressure of the surrounding fluid, so that the protrusion 244 is It is to prevent the surrounding fluid from flowing into the depressurized region 02 from the portion in contact with the wall surface 03 and the floor surface 04 as much as possible. That is, when the decompression container is adsorbed on the wall surface 03 and the floor surface 04, the adsorption seal 2
The protrusion 244 of the third lip portion 24 always contacts the wall surface 03 and the floor surface 04, and the depressurized area 02 is defined in the contacted portion. That is, since the inner space is decompressed with the contact portion as a boundary, the lip portion 24
Is always the wall surface 03 and the floor surface 04 due to the pressure of the surrounding fluid.
Thus, the suction seal 23 can have a high-performance sealing function because the protrusions 244 are pressed against the surface and follow the unevenness of the surface to be constantly in contact with the surface. The effect of the intermediate portion 25 of the suction seal 23 according to the preferred embodiment of the present invention will be described. Since the intermediate portion 25 can freely expand and contract in the direction toward and away from the surface, the lip portion 24 thus has an uneven surface. Since the lip portion 24 freely moves in the direction of approaching and separating from the surface following the above, the lip portion 24 can easily get over the unevenness when it encounters the unevenness existing on the surface.

In advance, the main portion 241 of the lip portion 24 and the fixing portion 26 will be described. Are formed on parallel surfaces, and then, in the fixed portion 26 and the intermediate portion 25 of the suction seal 23, the main portion 241 starts from the connecting portion with the main portion 241.
