Abstract
A joint seal of a constant velocity universal joint which has a sealing effect relative to a shaft journal includes an axial securing sleeve which is connected to the inner joint part and which ends in individual axial fingers which radially elastically engage an annular groove in the shaft journal, wherein the ventilation channels for the joint interior of the constant velocity universal joint are formed by axial slots between the individual axial fingers which freely end in the interior of the rolling boot and can be closed towards the outside of the rolling boot by a sealing lip which is formed on to the rolling boot, which, in the position of rest, annularly sealingly contacts the shaft journal and which, at an increased speed, lifts off the shaft journal to expose the ventilation channels.
