Beschreibung
Zusammenfassung:	A double-offset plunging type constant velocity universal joint includes inner and outer joint members each having six linear track grooves extending along an axial direction. The inner joint member has a coupling hole at a center portion thereof for coupling a shaft. Six torque transmission balls retained by a cage are incorporated between the linear track grooves of the inner and outer joint members. A ratio TCAGE/DBALL of a minimum thickness (TCAGE) of the cage to a diameter of the torque transmission ball (DBALL) is from 0.225 to 0.245, wherein a ratio DBALL/DS of a diameter (DBALL) of the torque transmission ball to a spline large diameter (DS) of the coupling hole of the inner joint member is from 0.79 to 0.85, and wherein a ball contact ratio (ψ) of the torque transmission ball is from 1.08 to 1.12.
