PURPOSE:To improve adsorption movement, variation of a direction, and durability of a device, especially durability to excitation by a method wherein a movement direction varying mechanism for a device to process a wall surface as it is moved in a state to be adsorbed on a wall surface is brought into surface contact with a body part for support. CONSTITUTION:A rubber hose 3 is communicated with a vacuum suction device, a space formed with a cylinder body 1 with a cover, an adsorption seal 2, and a wall surface is brought into a negative pressure state, and a whole device is adsorbed on the wall surface W. With an exciting device 11 actuated, the whole of the device is vibrated leftwardly obliquely upwardly to repeat rocking based on the wall surface W, and the device is moved leftward. During this movement, a wall surface processing device mounted to the cylinder body 1 with a cover is actuated to continue processing of wall surface. When the moving direction of the device is varied, a chain wheel 14 is rolled in an engaged state along a chain 6 with the aid of a geared motor 12. This constitution causes slide movement of revolving guide bodies 8, 8, 8, and 8 in an integrally formed state as they are brought into surface contact with an annular recessed groove 5, and causes movement of the exciting device 11 along with the slide movement of the revolving guide plates and the stop of the device in a proper position. |
