摘要：
In order to decrease internal friction of a heat engine that converts a reciprocating motion of a piston into a rotational motion, a piston apparatus (1) forms an air bearing between a crankshaft (30) and a bearing unit (9B) provided in a crankcase (9) and between an eccentric portion (30c) of the crankshaft (30) and a large end portion (201) of a connecting rod (20) by feeding a gas therebetween from a crank-side hollow portion (31) of the crankshaft (30). The piston apparatus 1 also forms an air bearing between a piston pin (40) and a small end portion (202) of the connecting rod (20) by feeding a gas therebetween from a piston pin-side hollow portion (43) in the piston pin (40).
