<P>PROBLEM TO BE SOLVED: To provide a constant velocity universal joint, a driving transmission device and an image forming device, capable of reducing a variation in nonuniformity of the one rotation transmission due to an engagement combination of an outer ring and a cage. <P>SOLUTION: The sum of a maximum angle error between through-holes of the cage 150 and a maximum angle error between track grooves of the outer ring 140 is set to 1.0° or less, and even when the engagement combination of the cage 150 and the outer ring 140 is in either case, the nonuniformity of the one rotation transmission can be restrained to an allowable level or less, and reduction in constant velocity performance of a photoreceptor 2 being a rotary body can be restrained. <P>COPYRIGHT: (C)2009,JPO&INPIT |
