PROBLEM TO BE SOLVED: To easily mount a waterproof cover by forming a slit part in the direction same as the fluorescent tube inserting direction on a point of one end of an inner socket, closing the other end, forming an opening on one end of an outer socket, and forming an opening on the other end for pushing out the inner socket in the direction opposite to the fluorescent tube inserting direction. SOLUTION: A slit part 5a is formed on a point of one end of an inner fluorescent lamp socket 1a, and the other end is closed. An opening 6 is formed on one end of an outer fluorescent lamp socket 1b, and an opening 7 for pushing out the inner fluorescent lamp socket 1a is formed on the other end. When the inner fluorescent lamp socket 1a is pushed out in the fluorescent tube inserting direction from the opening 7 of the outer fluorescent lamp socket 1b, the slit part 5a is externally opened by a contact plate 8, which expands a waterproof cover 4 to mount a fluorescent tube 2. The fluorescent tube 2 and the inner fluorescent lamp socket 1a can be covered by the waterproof cover 4 by stopping the pushing-out of the inner fluorescent lamp socket 1a.
