Abstract: A piston having a crown and a body connected together by bolts. The bolts pass through an annular gap defined by a pair of concentric ring members located between the crown and the body. One of the ring members is relatively resilient and the other ring member is relatively rigid. Such a construction reduces fretting between the crown and the body when the piston is in operation in an engine.
