To provide an external joint member appropriate for a long stem type constant velocity universal joint in which the quality of a welding part is improved, manufacturing costs are reduced by omitting or reducing post-processing and the quality is stabilized by surely checking the welding part.
An external joint member 11 for a constant velocity universal joint 10 comprises: a cup part 12 with which a track channel 30 to engage torque transmission elements 19, 41 thereto is formed along the inner circumference; and a shaft part 13 formed on the bottom of the cup part 12. The external joint member 11 is formed by bonding two or more components comprised of a cup member 12a forming the cup part 12 and shaft members 13a, 13b forming the shaft part 13 and a hollow cavity part 47 is sealed by bonding. The bonding is performed by melt welding and in any one of the components includes an vent hole 29 communicated to the hollow cavity part 47.
