Abstract:
1. A cylindrical sliding bearing, comprising: a. a bearing layer; b. a backing layer; c. the bearing layer including a first circumferential surface forming a shaft supporting radially internal face, said first circumferential surface having a radial rigidity, wherein said radial rigidity of the first circumferential surface against a radial compression force applied thereto by a shaft varies in a circumferential direction such that the first circumferential surface includes a first radial rigidity bearing area and a second radial rigidity bearing area, said first radial rigidity bearing area being more rigid than said second radial rigidity bearing area; and a second circumferential surface; d. wherein the second circumferential surface is joined to the backing layer; e. wherein the radial rigidity of the first circumferential surface is adjusted by changing a thickness of at least one of the bearing layer and the backing layer; f. wherein the radial rigidity of a cylindrical surface of a housing bore into which the cylindrical sliding bearing is fitted against the radial compression force; varies in a circumferential direction whereby the cylindrical surface includes a first radial rigidity area and a second radial rigidity area, the first radial rigidity area being of higher rigidity than the second radial rigidity area, and wherein the second radial rigidity bearing area overlaps the first radial rigidity area as seen radially.
