To provide a crank transmission device for an internal combustion engine in the form of rotating balance weights in the height of at least one connecting rod bearing part in these connecting rod bearing parts between the two balance weights 42, 44 arranged on a crankshaft 24 by arranging the balance weights 48 on a balance shaft for compensating for inertia force of first order.

The balance weights 48 arranged on the balance shaft 46 have at least one cutout part 54 to thereby reduce an interval r between the crankshaft 24 and the balance shaft. Thus, the residual moment induced by the balance shaft can be reduced by a simple structure and a method.
