ンの制振構造。 a vertical member that abuts the lower end edges of the left and right skirt portions of the crankcase; and a bearing portion that is fixed at both ends to the vertical member and extends transversely to the crank axis, and that is provided on the bulkhead of the crankcase. In a device comprising a ladder-like frame made up of a plurality of horizontal members that cooperate to support a crankshaft, a hollow is recessed from the outside toward the crankshaft at the joint portion of the horizontal member to the vertical member. A recess is provided in the side surface of the transverse member that limits the side wall in the direction transverse to the crank axis of the through hole formed between the transverse members and accommodating the large end of the connecting rod. A vibration damping structure for an engine, characterized in that it is configured so as not to provide a hollowed-out recess.
