Claims

[Claims for Utility Model Registration] (1) A cylindrical outer member, and an inner member having a convex spherical bearing surface on its outer peripheral surface and fitted into the outer member such that the bearing surface is located within the outer member. and between the inner member and the outer member,
a pair of bearing rings each having a concave spherical bearing surface that slidably engages with the bearing surface of the inner member, and which are arranged at appropriate intervals in the axial direction over the entire circumference; It comprises a backup ring disposed on the end face side, and an elastic seal ring which is held between at least the bearing ring on the opening side of the outer member and the backup ring and whose tip portion is in sliding contact with the inner member, and the elastic seal ring has a tip end slidably in contact with the inner member. The rings are substantially integrated by engaging the opposing end surfaces of the rings or the opposing end surfaces of the bearing ring, the elastic seal ring, and the backup ring with each other, and the open end of the outer member is provided with the backup ring. A spherical plain bearing characterized in that a radially inward bent edge is formed to press an outer end surface of a ring. (2) The outer diameter corners of the outer ends of both bearing rings are formed into circumferential stepped portions, and the elastic seal ring is formed with a circumferential protruding portion that fits into the stepped portions, and protrudes from the side surfaces of the stepped portions. The scope of the utility model registration claim where the end surfaces of the parts are brought into contact and engaged
The spherical plain bearing described in 1). {3} A utility model in which each of the meshing engagements is a fit between a concave portion of one member and a convex portion of the other member of a plurality of concavo-convex portions formed at equal intervals on the circumference on the end faces of both members. A spherical plain bearing according to registered claim (1) or (2). (4) The scope of the utility model registration claim, in which the contacting and opposing end surfaces of the bearing ring and the backup ring and the contacting and opposing end surfaces of the bearing ring, the elastic seal ring, and the backup ring are formed in a plane perpendicular to the axis of the bearing. The spherical sliding bearing according to any one of (1) to (3).
