Abstract
A two-cycle engine includes a crankshaft that has shafts on both sides and a crankcase that pivotally supports the shafts of the crankshaft through bearings. A collar is circumferentially provided on an outer ring of one of the bearings that supports one of the shafts on a side at which a low load is applied. The crankcase is provided with an inserting portion into which the one of the bearings is inserted. The inserting portion penetrates the crankcase while keeping a constant diameter. An engaging portion with which the collar is engaged from an inner side is provided in an inner portion of the inserting portion.
