Provided is a fixed type constant velocity universal joint which can prevent stick slip from occurring due to lack of lubricity, and prevent abnormal noises from occurring at low temperatures, even during use in an extremely cold region. The fixed type constant velocity universal joint which has grease enclosed therein and is provided with an outer joint member 23 having an inner surface in which a plurality of track grooves 22 are formed, an inner joint member 26 having an outer circumferential surface in which a plurality of track grooves 25 are formed, a plurality of balls 27 for transmitting torque provided between the track grooves 22 of the outer joint member 23 and the track grooves 25 of the inner joint member 26, and a cage 28 for retaining the balls 27, in which the grease contains 80% by mass or more of paraffinic mineral oil or a mixture of paraffinic mineral oil and synthetic hydrocarbon oil with respect to the total mass of a lubricant component contained as base oil, the paraffinic mineral oil accounts for 70% by mass or more of the total mass of the lubricant component, and the grease contains 3 to 8% by mass of a thickener with respect to the total mass of the grease, so that the grease prevents abnormal noises from occurring at low temperatures.
