Abstract

A composite drive shaft having a pair of aligned, diametrically opposed bores in which a cross-shaped coupling forming part of a universal joint is pivotally connected. This construction materially reduces the weight of drive shaft/universal joint combinations by eliminating the steel Hookes joint yokes which heretofore have been bonded into the shaft.
