A universal joint component is used for connecting two members, such as a reflector and a lamp body. The universal joint component includes a shaft, an installation section formed on one end of the shaft, and a spherical head formed on the other end of the shaft. The spherical head includes a joint base, a top end, and at least one gap formed on a side of the spherical head between the top end and the joining base. The gap is formed of a groove or through hole so as to straddle a phantom line substantially passing through a center of the spherical head and perpendicularly intersecting a shaft axis of the shaft. Split head sections are defined by the at least one gap so that the split head sections flexibly deform when the spherical head is inserted into a spherical socket.
