PURPOSE:To regulate movement in the radial direction and simplify manufacture by engaging each other both ends of a plate or a composite layer plate formed in the cylindrical shape of an inner ring and an outer ring, forming a joining part regulating three directional movement in an axial, diametral and circumferencial, and directions providing a locking part on the end of the joining part. CONSTITUTION:A locking groove 5 of angular section is parallelly provided on the inner circumference of an outer ring which is formed in a cylindrical shape by winding a steel plate to make contact an an joining part 4, and nitryl rubber is injected, vulcanized and shaped between an inner ring 3 and the outer ring 1 to form a cushioning material 2. And the inner ring 3 is coated with a porous sintered metal 8 on the inner circumferential surface of its base material 6 of a steel plate, synthetic resin membrane 9 which contains a filler is impregnated thereon, and formed in a cylindrical shape by bringing both ends in contact with each other at a joining part 11. Further, oil grooves 12 are provided on the inner circumferential side of the inner ring 3, locking grooves 13 of angular section are provided on the outer circumference, and end part mating faces 14, a central mating face 15, convex parts 16 and concaves 17 are provided on the joining part 4. Accordingly, circularity is good, and manufacture can be simplified without needing grinding finish processing.
