PROBLEM TO BE SOLVED: To prevent the fluorescent lamp from coming off and falling off a lamp holding part consisting of the base part of a socket. SOLUTION: Projected parts 2 are provided for inner peripheries of a lamp holding part (a) consisting of a base part 1. The projected parts 2 are buried in grooves L', formed at the outer circumference of a fluorescent lamp L so as to allow the fluorescent lamp L to be mounted to the base part 1. Each projected part 2 of the lamp holding part (a) consisting of the base part 1, is buried in such a state that it is fitted in the grooves L' of the fluorescent lamp L, so that the vertical movement of the fluorescent lamp L is thereby restricted by the base part 1. |
