PROBLEM TO BE SOLVED: To provide an inexpensive wheel having rubber that prevents raising and carrying of mud and has light weight and high strength. SOLUTION: A disk part 20 of the wheel 10 having the rubber comprises a first disk part 23 mounted to a machine body and a second disk part 21 disposed radially outside the first disk part 23 and fastened to the first disk part 23 via a bolt and a nut. The first disk part 23 mounted to the machine body and applied with a strong force is made thicker than the second disk part 21 radially outside thereof, so that deformation due to stress or the like can be prevented. The second disk part 21 is disposed radially outside the first disk part 23 and the applied force is weaker than that to the first disk part 23, so that the thickness of the second disk part 21 can be thinner than that of the first disk part 23 while preventing the deformation. The thickness of the disk part 20 of the wheel 10 having the rubber is partially changed, so that the weight can be reduced while securing the strength. COPYRIGHT: (C)2003,JPO
