PROBLEM TO BE SOLVED: To obtain a fixation structure in which an elastic claw is pressed so as to release its coupling operation and in which a metal plate is replaced easily, by forming a coupling part having a structure in which the elastic claw is coupled to a housing from the inside and in which the elastic claw can be pressed from the outside to a direction in which its coupling operation is released. SOLUTION: Lead legs 12 of a light emitting diode 4 are inserted respectively into continuity holes 11 in a metal plate 3 so as to be coupled. Then, cut grooves 10 which are formed in leg parts 8 of the metal plate 3 are set on a cord 2, the metal plate 3 around the light emitting diode 4 is pressed, and the cut grooves 10 are force-fitted to the cord 2. In this state, elastic claws 9 at both ends of the metal plate 3 are coupled to lower edges of transverse bars 7, and it is possible to prevent the metal plate 3 from being removed from a housing 1 due to the encroaching force of the cut grooves 10 the cord 2. Then, when the metal plate 3 is a defective, a thin tool or the like is inserted from an open part on the lower side of the transverse bars 7, and the elastic claws 9 are pressed. Then, the metal plate 3 can be replaced easily. |
