<p>Provided is a sliding ball type constant velocity joint for a vehicle, which can minimize vehicle vibration by forming a track groove pair by two track grooves (21) of an outer race (2) and an inner race (3) to reduce a contact area between the inner race (3) and a cage (5), and can reduce the manufacturing cost by reducing the number of processing steps of the cage by forming the number of windows of the cage to half that of balls. The sliding ball type constant velocity joint includes an outer race (2) rotating by receiving rotational power from an end of the shaft and having a track groove pair formed by a pair of track grooves on its inner surface, an inner race installed in the outer race having a track groove pair formed by a pair of track grooves on its outer surface (51) to correspond to the track groove pair of the outer race, a plurality of balls (4) installed in the track groove pairs formed in the outer race (2) and the pair of track grooves formed in the inner race (3), for transmitting the rotational power of the outer race to the inner race, and a cage having windows for accommodating and supporting each two of the balls.</p> |
