Abstract

PURPOSE:To obtain reduction performance of wear to a ring groove without causing the necessity for casting together with a friction resistant alloy to the ring groove, by forming the ring groove in an annular groove, formed in the periphery of a piston, through a pair of elastic wear resistant rings. CONSTITUTION:A large annular groove 4 is formed in the periphery of a ring area 2 at the side of a piston head 3 in a piston main unit 1 of aluminum alloy, and a set of upper and lower, the first and second small annular grooves 61, 62 are formed respectively to the peripheral surface of the innermost wall 5 of said large annular groove 4. Then the first wear resistant ring R1 is elastically fitted to the first small annular groove 61, while the second wear resistant ring R2 is elastically fitted to the second small annular groove 62. In this way, a top ring groove 8, formed with a trapezoidal longitudinal section and provided with reduction performance of wear, for housing a top ring P, can be generated between the first and second wear resistant ring R1, R2.
