トン。[Claims for Utility Model Registration] 1. A large number of inorganic long fibers are arranged in a ring shape and become denser as they approach the outer periphery in the radial direction, and inorganic short fibers having a larger expansion coefficient are intertwined around the outer periphery of the long fibers. What is claimed is: 1. A piston for an internal combustion engine, characterized in that an annular body formed by the above method is embedded in the outer periphery of the piston along the skirt shoulder of the piston. 2. The piston for an internal combustion engine according to claim 1, wherein the surface of the long inorganic fibers is scratched in the longitudinal direction. 3. The piston for an internal combustion engine according to claim 1, wherein projections are provided on the surface of the inorganic long fibers.
