In a constant velocity universal joint comprising outer 3 and inner 4 members with convergent arcuate ball tracks 19, 18, the balls 20 are urged by the track convergence towards a guide member 26 which locates the balls axially and slides in a plane radial to the outer member in accordance with the angularity of the joint. The guide member 26 has a substantially conical surface 28 shaped to retain the balls in the median plane of the joint and is moved radially on a surface 25 of an end outer member 12 by pin 30 rigid with the inner member and having a part spherical end surface 35 retaining the inner member axially relative to the outer member. The outer member 3 has a flange 14 co-operating with a flexible dust cover 36 clipped to the shaft 6 of the inner member; the shaft 6 having a ball-splined sliding joint with a tubular shaft 8. In a second embodiment, the balls are retained in a split cage which is located by the guide member.
