<p>A socket portion (20, 120a, 120b) is provided to project from one side surface of a transformer receiving portion (3, 103a, 103b) to thereby form a body case (2, 102a, 102b), and a lighting transformer (30, 130a, 130b) is received in the transformer receiving portion (3, 103a, 103b) so that a high voltage side output end of a secondary coil (49, 143) of the lighting transformer (30, 130a, 130b) is electrically connected to a terminal (23, 123) provided in the socket portion (20, 120a, 120b) and a primary coil (50, 145) of the lighting transformer (30, 130a, 130b) is connected to an external electric path directly or through a circuit portion. Accordingly, the transformer receiving portion (3, 103a, 103b) and the socket portion (20, 120a, 120b) are integrally formed with each other to thereby form a unit structure. <IMAGE></p> |
