A fixed type constant velocity universal joint includes an outer joint member, an inner joint member, a plurality of balls interposed between the outer and inner joint members, and a cage to hold the plurality of balls. At least one of the plurality of track grooves of the outer joint member and the plurality of track grooves of the inner joint member is formed by cold-forging finishing. The outer joint member, the inner joint member, the balls, and the cage are assembled to each other based on matching in which the plurality of balls and the cage each having a rank corresponding to a measured value of a pitch circle diameter of the outer joint member and to a measured value of a pitch circle diameter of the inner joint member, which have been arbitrarily selected, are selected with respect to the arbitrarily selected outer and inner joint members.

1. A method of manufacturing a fixed type constant velocity universal joint, the fixed type constant velocity universal joint comprising: an outer joint member having a cupped shape so as to open at one end and having an inner spherical surface provided with a plurality of track grooves extending in an axial direction;an inner joint member having an outer spherical surface provided with a plurality of track grooves extending in the axial direction in pairs with the plurality of track grooves of the outer joint member;a plurality of balls interposed between the plurality of track grooves of the outer joint member and the plurality of track grooves of the inner joint member so as to transmit torque; anda cage interposed between the inner spherical surface of the outer joint member and the outer spherical surface of the inner joint member so as to hold the plurality of balls,wherein at least one of the plurality of track grooves of the outer joint member and the plurality of track grooves of the inner joint member is formed by cold-forging finishing,the method comprising: ranking, according to outer diameters of the plurality of balls, cages having pocket widths in conformity with the outer diameters of the plurality of balls without ranking outer joint members and inner joint members according to their pitch circle diameters (PCDs);measuring a PCD of the outer joint member, which has been arbitrarily selected, and a PCD of the inner joint member, which has been arbitrarily selected; andcombining the outer joint member, the inner joint member, the plurality of balls, and the cage with each other based on matching in which the plurality of balls and the cage, each having a rank corresponding to a measured value of the PCD of the arbitrarily selected outer joint member and to a measured value of the PCD of the arbitrarily selected inner joint member, are selected with respect to the arbitrarily selected outer joint member and the arbitrarily selected inner joint member.
