PURPOSE:To ensure positive adsorption travelling even in water and muddy bodies, by installing a plurality of wheels to a travelling body, by using at least one of said wheels as a magnetic wheel while mounting a drive means and by disposing a floating means to the travelling body. CONSTITUTION:Wheels 3 are installed to both end portions of a travelling body 1 in a form that the wheels contact with an adsorptive surface 2 while a rotary shaft 4 is disposed to a central portion of said body 1, and an axle 6 is mounted to the lower end through a supporting portion material 5. A magnetic wheel 7 is installed to the axle 6 so that the wheel 7 rolls on the adsorptive surface 2 while a worm gear 8 is fastened. Meanwhile, an air motor 9 is mounted to the supporting portion material 5, and the worm 10 is engaged with a worm gear 8. A gear 11 is fixed to an upper end of the rotary shaft 4, and engaged with a pinion 13 of an air motor 12 installed onto the travelling body 1. 14 is a floating tank shaped in a hollow airtight condition. |
