Abstract
In a crankshaft structure of two-cycle internal combustion engine, a crank web is provided with a reduced diameter portion at one end thereof coming in the proximity of a bearing which rotatably carries a crank journal and a sealing member is disposed on the outer periphery of the reduced diameter portion. This arrangement advantageously reduces the axial length of the crankshaft while keeping a desired length of the supporting part of the crank web fitted with the crank journal.
