Abstract

PURPOSE:To improve sealing ability and durability in such a way that an annular groove is formed on the sliding contact face of a sliding ring, a narrow and long groove in forward cant in relatively turning direction is formed on its outer peripheral side, and a narrow and long groove in rearward cant in relatively turning direction is formed on its inner circumferential side. CONSTITUTION:In the sliding contact face 5a of a driven ring 5, its imaginary center point 0 is assumed as practically the same center point, and an annular groove 6 is formed at the place away more than a quarter each sliding contact face's width d from the outer peripheral end 5b and from the inner circumferential end 5c of the sliding contact face 5a. Besides, on the outer peripheral side of the annular groove 6, a narrow and long groove 8 in forward can in the diametral direction of the sliding contact face 5a in the turning direction of the driven ring 5, and on the inner circumferential side of the annular groove 6, a narrow and long groove 7 in rearward cant in the diametral direction of the sliding contact face 5a in the turning direction c of the driven ring 5 are formed to respectively reach the outer peripheral end 5b or the inner circumferential end 5c of the driven ring 5.
