摘要： PROBLEM TO BE SOLVED: To provide a constant velocity universal joint in which play at a shaft connection portion is less likely to occur and having a spigot-socket fitting structure capable of firmly connecting an inner joint member and a shaft together. SOLUTION: The constant velocity universal joint includes an outer joint member, the inner joint member inserted into the outer joint member and a torque transmitting member disposed between the outer joint member and the inner joint member so as to transmit torque. The constant velocity universal joint has the spigot-socket fitting structure M by which the inner joint member and the shaft 5 inserted and fitted in a shaft hole of the inner joint member are connected together. A hardened layer S by induction hardening is formed on the outer diameter side of the inner joint member. The inner diameter side of the inner joint member is in an unquenched state. A projection 35 arranged on the outer diameter surface of the shaft 5 and a depression 36 arranged on the inner diameter surface of the shaft hole 22 of the inner joint member and fitting on the projection 35, are in intimate contact with each other in their entire regions at a fitting and contact portion 38.

摘要： PROBLEM TO BE SOLVED: To provide a bearing device for a wheel capable of restraining looseness in the circumferential direction, superior in connection workability of a hub wheel and an outside joint member of a constant velocity universal joint, and superior in maintainability capable of separating the hub wheel and the outside joint member of the constant velocity universal joint. SOLUTION: This bearing device for the wheel is provided by separably joining the hub wheel 1 and a shaft part 12 of the outside joint member of the constant velocity universal joint 3 fitted to and inserted into a hole part 22 of the hub wheel 1 via a recess-projection fitting structure M. The recess-projection fitting structure M is constituted by pressing a projection part 35 arranged in any one of an outer diameter surface of the shaft part 12 of the outside joint member and an inner diameter surface 37 of the hole part 22 of the hub wheel 1 and extending in the axial direction, in the other in the axial direction, and forming a recessed part 36 fitted in close contact to the projection part 35 by the projection part 35 in the other, and closely contacting the whole area of a fitting contact part 38 of the projection part 35 and the recessed part 36. The recess-projection fitting structure M allows separation by impartment of extraction force in the axial direction. A shaft part press-in guide structure M1 is provided.

摘要： PROBLEM TO BE SOLVED: To enable production of an outside joint member having a long shaft at low cost. SOLUTION: An outside joint member 31 serving as a base member integrally having a cup portion 32 corresponding to a cup portion 12 formed with a plurality of truck grooves on the inner diametrical surface and a shaft portion 33 axially extending from the bottom portion of the cup portion 32 is manufactured. The outside joint member 31 is parted at one axial position to manufacture a first parted member 34 and a second parted member 35, and an intermediate member 14 is disposed between the end surfaces 34a and 35a of both parted members 34 and 35. Both end surfaces 14a, 14b of the intermediate member 14 are joined to the end surfaces 34a, 35a of the parted members 34, 35, respectively. Thereby, an outer joint member 11 provided with the cup portion 12 and a long shaft portion 13 axially extending from the bottom portion of the cup portion 12 is manufactured.
