A driveshaft ( ) having two ball type constant velocity fixed joints ( ), a shaft part ( ) connecting said two joints, and an axial plunging part ( ) arranged in said shaft part ( ). The ball type constant velocity fixed joints ( ) each comprise: a bell-shaped outer joint part ( ) provided with internally positioned first ball tracks ( ); a hub-shaped inner joint part ( ) provided with externally positioned second ball tracks ( ) and arranged inside said outer joint part ( ); balls ( ) engaging pairs of first ball tracks ( ) and second ball tracks ( ); and an annular ball cage ( ) with circumferentially distributed cage windows in which the balls are held in a common plane. The pairs of first ball tracks ( ) and second ball tracks ( ), when viewed in a longitudinal section, form opening angles (&agr; , &agr; ) relative to one another for controlling the balls ( ) in the ball tracks. The opening angles (&agr; , &agr; ) of the pairs of first ball tracks and second ball tracks at both ball type constant velocity fixed joints ( ) open in the same direction.
