摘要：
A piston pin made of ceramics is journalled in piston bosses of a piston made of aluminium alloy. Intermediate members are installed in bearing bores to receive therein terminal end portions of the piston pin. The intermediate members are made of metal which is intermediate in thermal expansion coefficient between the aluminium alloy forming the piston and the ceramics forming the piston pin.
