ストン。A ceramic top plate is formed by fitting an anti-shrinkage ring made of an Italian expansion metal around the small diameter part of the top plate made of ceramics, and then casting the ceramic top plate with an aluminum alloy. In the cast piston, an annular C groove is formed on the outer periphery of the small diameter part of the ceramic top plate, and at least one hollow cylinder is provided to form a gap between the anti-shrinkage rings, and a part of the aluminum alloy is formed in the small diameter part of the ceramic top plate. A ceramic cast piston, characterized in that the piston is firmly engaged with the groove through the groove.
