するエンジンの構造。[Claims for Utility Model Registration] A small end that is fitted into a piston pin supported by a pin boss portion of a piston, and a large end that is fitted into a crank pin of a crankshaft that is rotatably supported by a crank bearing. When viewed in the axial direction of the crankshaft, the clearance between the large end locking part on the transmission side and the large end formed on the crankshaft is determined by the transmission side pin boss. An engine structure characterized in that the clearance is set to be larger than the sum of the clearance between the small end and the transmission side crank bearing locking part formed on the crankshaft and the crank bearing. .
