The electric circuit pieces 64 are formed of a conductive plate, and two electric circuit pieces 64 are arranged in each of the recesses 65 and 66 on both sides of the body 62 according to each wattage. Each electric circuit piece 64 is formed by pressing a pair and integrally connected at a separation part 72, and a lamp pin receiver 75 serving as a lamp contact piece is provided at the lower end, and the terminal 59 is provided at the upper end.
is formed, but this is the connector part 26a,
It is integrally formed by being bent along the inclined surface of 26b. The lamp pin receiver 75 is made by bending a plate-like body into a cylindrical shape, and has a mounting piece 7 at one end.
The lower end of the electric circuit piece 64 is bent 77 in steps by a length corresponding to the radius 72a of the lamp pin receiver 72, and the mounting piece 78 is held at the tip thereof, and the lower end of the electric circuit piece 64 is bent in the width direction of the electric circuit piece 64. is caulked and fixed in a bent state (Figures 22 and 23).
With this configuration, the electrical circuit pieces 64a and 64b of the same width disposed in the recesses 65 and 66 on both sides are symmetrical except that the terminals 59 are bent in different directions, so that the components of the left and right electrical circuit segments are different from each other. This means that it can be shared. Assembly is done using the recesses 6 on both sides of the body 62.
When the lamp pin receiver 75 is accommodated in the recess 79 formed corresponding to the lamp pin receiver 75 of 5, 66, the electric circuit piece 64 is inserted into the guide strip 6 of the recesses 65, 66 on both sides.
7, the terminal 59 is placed in the guide groove 73, and its tip is fixed by caulking with a caulking projection 74 (FIG. 20). In this state, the lid 63 is fitted into the recesses 65 and 66 on both sides, and the projection 69 is press-fitted into the press-fitting boss 68. As a result, the lamp pin receiver 75 is located inside the lamp socket holes 24 and 25, the electric circuit piece 64 is held down by the holding protrusion 70, and the separation part 72 is insulated and separated by the insulating plate 71. Note that this insulating plate 71 may be provided on the body 62 side.

In this invention, the connection part of the lamp socket and the connection receiving part of the lighting electric component are not only connected directly as in the embodiment, but also may be connected through a lead wire.
