Abstract
A cross-groove type homokinetic joint which requires no boot adaptor and is thus less expensive and which is provided with an arrangement for preventing the balls from dropping out while keeping a large working angle of the shaft. The cross-grooved homokinetic joint has an inner ring having grooves in its outer surface, balls received in the grooves of the inner ring, a cage retaining the balls, and an outer ring having grooves in its inner surface. The balls are guided by the grooves of the outer ring. This joint has no boot adaptor. The boot is directly fixed to the outer ring. A circlip is fitted on the inner surface of the outer ring near its open end to prevent the balls from dropping out.
