It is formed by standing up in the shape of an abbreviation,
A cord clamp portion 67 for clamping the harness cord 7 is formed at the other end.

The cord clamp part 67 is formed by laterally projecting from one end of the support member 6 formed in a plate shape, and has an opening 67a with one end cut out in the projecting piece, and a through hole 67 communicating with the opening 67a. b is formed.

This opening 67a is easily inserted into the through hole 67b by forcibly inserting the harness cord 7.7 led out from the bottom of each holder 5. It is designed so that there is no risk of it coming out.

Since the configuration is as described above, the holder 5 is connected to the support member 6.
To attach it to the housing 1 via the support member 6, first

Therefore, the cord clamp portion is provided to extend laterally from one end of the support member 6, and this cord clamp portion 6
Since the neck cord 7 is firmly inserted and clamped into the opening 67a, there is no risk of it being pulled out from the opening 67a even if the cord is exposed to vibrations of the vehicle or is stretched by something.

Although the holder 5 to which the above-mentioned support member 6 is attached and fixed is a rear exchange type (bayonet type) holder, the present invention is not limited to this, and other one-touch type holders may be used.

In addition, although the abbreviated light shielding part 66 provided upright at one end of the support member 6 has been described, the light shielding part 66 is not limited to an L shape, and the light from the bulb 3 passes through the heat radiation hole and leaks to the rear of the clamp. Any structure that prevents this is fine.

Furthermore, the cord clamp portion 67 provided at the other end of the support member 6 is not limited to the above-described embodiments, but may be formed by projecting from one end of the support member.

As is clear from the above-described embodiments, the vehicular lamp of the present invention is a lamp in which a bulb is disposed via a holder in a lamp chamber defined by a housing and a lens disposed in front of the housing. The holder is removably attached to a support member that is engaged with a pair of opposing elastic engagement legs that protrude from the rear of the housing, and another opposing edge that is different from the retaining edge of the support member with the elastic engagement legs is attached. A light shielding portion and a cord clamping portion are respectively projected from the edges, and the light shielding portion covers the heat radiation hole of the housing, and the harness cord led out from the holder is clamped by the cord clamping portion. The cord is clamped short so that the harness does not become complicated at the rear of the housing and can be wired neatly. Also, the harness cord can be securely clamped with one touch without getting tangled at the rear of the housing, and can be hung on other parts. There is no fear that the material will come out.

Further, since the light shielding portion is provided at one end of the support member, it is possible to prevent light from leaking to the rear of the housing from the heat radiation hole provided in the side wall of the housing without using a separate member.
