Abstract
A hollow tubular balance shaft member having bobweights of minimal mass. The tubular member is preferably made by a deep drawn process. One or more bobweights is positioned in the tubular member during formation thereof. The invention can be used for all vehicle engines which need counterbalancing mechanisms, such as 90.degree. V-6 engines and inline four cylinder engines. Various mechanisms can be used to secure and hold the bobweights in position in the tubular member, such as welding, adhesive bonding, staking, brazing, and the like. One end of the balance shaft member has a drive member on which a drive gear is positioned and used to rotate the balance shaft by the engine.
