Abstract
A crankcase of an internal combustion engine includes protruding portions formed on an outer surface of the crankcase which are constituted of a pair of left and right wall members, and a vibration isolating rubber is fitted between the wall members. The crankcase configured in this manner prevents the generation of sounds from a protruding portion of the crankcase and is light-weight.
