Abstract
In a multiple cylinder engine having a plurality of cylinders, balance weights are centrally arranged so as to suppress the secondary vibration in a space corresponding to the second bearing journal counted from the opposite side of the transmission among a plurality of the bearing journals of the crank arms. In addition, the weights can be less light-weight and space efficiency in the engine room will become high.
