PURPOSE:To secure the roughness of a bearing as well as to protect a joint from getting loose by providing the end face of the joint with an engaging stopper for regulating its movement in the radial direction. CONSTITUTION:One side of the joining end, which forms the joint 11 of a cylindrically rolled multilayer bearing 10, is provided with a convex section 12 shaped such as a dove tail, and the other side of the joining end is provided with a concave section 13, which is cut out to the same shape so that is engages with the convex section 12. In addition, a protrusion 14 is formed on the end face of the joining end of the convex section 12, and a concave groove 15 which is engaging with the protrusion 14, is formed on the end face of the joining end of the concave section 13 and thereby, an engaging stopper 16 is made up of the protrusion 14 and the concave groove 15. In the cylindrically rolled multilayer bearing 10, which is made up in such a manner as above, a movement of its joint 11 along direction of the axis and of the circumference can be regulated by means of the engagement between the concave and convex sections 13, 12, and also, its movement in the radial direction can be regulated by means of the engagement between the protrusion 14 and the concave groove 15 forming the engaging stopper 16. |
