摘要：
A two-cycle engine (10) includes a crankshaft (13) that has shafts (17, 18) on both sides and a crankcase (12) that pivotally supports the shafts (17, 18) of the crankshaft (13) through bearings (21, 26). A collar (29) is circumferentially provided on an outer ring of one of the bearings (26) that supports one of the shafts (18) on a side at which a low load is applied. The crankcase (12) is provided with an inserting portion (24) into which the one of the bearings (26) is inserted. The inserting portion (24) penetrates the crankcase (12) while keeping a constant diameter. An engaging portion (27) with which the collar (29) is engaged from an inner side is provided in an inner portion of the inserting portion (24).
