Abstract

In a balance shaft for a multi-cylinder in-line engine with at least two imbalance weight sections and at least one bearing structure wherein the balance shaft has imbalance weight sections being arranged symmetrically relative to the bearing position and at least one of the imbalance weight sections is connected to a further shaft section at an end facing away from the bearing position, a flexible coupling element that enables a deflection of the end of the connected imbalance weight section in the direction of the resulting centrifugal forces when the balance shaft rotates is provided between the end of the at least one imbalance weight section facing away from the bearing position and the further shaft section.
