PROBLEM TO BE SOLVED: To provide a double row eccentric thrust bearing easy to be increased in dimension thereof and easy to be reduced in weight thereof. SOLUTION: This double row eccentric thrust bearing has two outside cases 2 arranged opposite to each other in the axial direction and integrally joined with each other and an inside case 3 interposed between both the outside cases. Each of surfaces of the inside case 3 opposite to both the outside cases is locally provided with three or more inner races 5 divided and arranged along the circumferential direction. Each of the two outside cases 2 and 2 is locally provided with three or more outer races 4 divided and arranged in positions opposite to each of the inner races 5. A ball 6 as a rolling body is pinched between each of the opposite inner races 5 and the outer races 4. All of the movable range of each of the balls 8 in each of the races arranged by dividing is set in a range nearly corresponding to each other. COPYRIGHT: (C)2005,JPO&NCIPI
