| 1. An eccentric thrust bearing assembly comprising: a first radially outside member and a first radially inside member positioned
on a radially inner side of the first radially outside member; and a second radially outside member and a second radially
inside member positioned on a radially inner side of the second radially outside member, the second radially outside and inside
members disposed in opposing relation with the first radially outside and inside members,
wherein the first radially outside member opposes the second radially inside member at three or more first positions separately
located along a circumferential direction thereby clamping rolling elements therebetween, the rolling elements disposed at
the first positions, whereas the second radially outside member opposes the first radially inside member at three or more
second positions separately located along the circumferential direction and having a different phase from that of the first
positions, thereby clamping rolling elements therebetween, the rolling elements disposed at the second positions,
wherein the first radially outside member and the first radially inside member define a gap therebetween so as to be allowed
to move relative to each other in the radial direction and the circumferential direction, whereas the second radially outside
member and the second radially inside member define a gap therebetween so as to be allowed to move relative to each other
in the radial direction and the circumferential direction,
wherein the first radially outside member and the second radially outside member are integrally interconnected, whereas the
first radially inside member and the second radially inside member are integrally interconnected, and
wherein respective certain portions of the rolling elements are present on the same plane.
