Abstract: The mounting component for a cylindrical bushing is comprised of a holder into which a cylindrical bushing can be fitted. An opening is formed at one location in a circumference direction of the holder such that the opening extends in an axial direction. At the opening, the holder can be opened in an expanding manner. When the opening is closed, the inner circumference surface of the holder is tightly attached to the outer circumference surface of the bushings to effect a clamping fastening method wherein the bushing is fitted and fixed inside the holder. Joints are provided on the two opening edges, or in their vicinity, of the aforementioned opening, in such a way that the joints protrude toward the outer circumference surface, These joints are bonded by a coupling structure using plastic deformation, and thus maintain the opening in a closed state.
