Abstract
By casting a preformed member composed of a fiber reinforced material into a base material of a piston, a pair of crown reinforcing portions corresponding to respective pin boss portions are formed on a crown portion, and the pair of crown reinforcing portions are connected to each other along the piston pin axis by a connecting portion. Thus, the strength of the piston is increased by the crown reinforcing portions, and also, heat distortion of the crown portion is inhibited since the crown reinforcing portions integrally connected to each other by the connecting portion are formed so as to serve as a rigid member extending along the piston pin axis.
