BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lamp which is an interior lamp attached to a stay portion of an inside mirror of an automobile.

[0002]

2. Description of the Related Art In a conventional vehicle lamp of this type, a spot lamp portion is a bulb 5 as shown in FIG.
There is also one in which 0 is held by the earthing valve holder 51, the power supply valve holder 52 is brought into contact with the power supply side of the valve 50, and the earthing valve holder 51 and the power supply valve holder 52 are attached to the base 53. In this case, since the spring pressure of the power source valve holder 52 is applied to the valve 50, the earthing valve holder 51 is prone to fall in the acting direction of the spring pressure.

[0003]

However, in the conventional example, since the earthing valve holder 51 is prone to fall in the acting direction of the spring pressure, the position of the valve 50 becomes unstable and vibrations occur. , The valve filament was broken due to the impact, and the valve life was shortened, and the spot irradiation range setting specification was incorrect due to the valve filament deviation. Also, when the ground valve holder and power supply valve holder are attached to the base with rivets and the rivet part is used for energization, the rivet loosens due to the ground valve holder falling and the voltage drop due to electrical contact resistance increases However, there was a problem that the performance and reliability of the

The present invention solves the above problems and prevents the earthing valve holder from collapsing, the valve position is stable, and there is no valve filament breakage due to vibration or shock. The bulb life will be extended and the spot irradiation range setting specifications will not be disturbed.
An object of the present invention is to provide a vehicular lamp that has no voltage drop and can improve the performance and reliability of the lamp.

[0005]

In order to achieve the above object, the present invention is to hold a valve with a grounding valve holder and to contact the power supply valve holder with the power supply side of the valve to provide a grounding valve holder. And a vehicle lamp having a power supply valve holder attached to a base, wherein a grounding valve holder mounting portion and a power supply valve holder mounting portion are formed on a surface portion of the base, and the grounding bulb holder mounting portion is formed. A notch is formed in the center of the edge portion, and a stopper having a front T shape and having one side portion on the left and right sides is formed in the center portion of the edge portion of the notch portion. It consists of two legs following the holder and a mounting part following these legs, and this earthing valve holder is riveted to the base at that mounting part. Ri attached, characterized in that contact pieces of the left and right stopper edge portion of the leg portion.

[0006]

With this structure, the spring pressure of the valve holder for the power supply is applied to the valve, so that the earthing valve holder tends to fall in the acting direction of the spring pressure. Since the stopper is in contact with, it is possible to prevent the earthing valve holder from falling.

Therefore, the valve position is stable, the valve filament is not broken due to vibration and impact, the valve life is extended, and the spot irradiation range setting specifications due to the valve filament deviation do not occur. Also, when the ground valve holder and the power supply valve holder are attached to the base with rivets and the rivet part is used for energization, the rivet loosens due to the fall of the ground valve holder and the voltage drop due to electrical contact resistance increases, Since there is no rivet loosening, there is no voltage drop and the performance of the lamp,
The reliability can be improved.
