[0004] Therefore, the weight of the lighting fixture 10 increases, and the lighting fixture 10 cannot be supported by the cord adjustment tool 13 alone, and may fall off. In addition, even when a large external force is applied to the lighting device 10, the lighting device 10 may be displaced from the cord.

In order to prevent this displacement, the cord 1 is placed inside the lighting fixture 10 in which the cover 11 and the chassis 14 are integrated.
A cord stopper (not shown) for supporting the lighting fixture 10 was attached to the lighting fixture 10 and the cord 12 was stopped. However, the tip of a screw (not shown) for attaching the coat stopper to the chassis 1 projects from the chassis 14,
The appearance was sometimes impaired. In addition, there is a problem that the work is difficult to perform because the screws must be mounted inside the narrow chassis 14. Further, in order to prevent the screw from projecting, the cover 11 and the chassis 14
In some cases, the cord stopper 20 is separated from the upper side of the chassis 14 by screws 21 as shown in FIG.

However, in this method, two parts, the cover 11 and the chassis 14, are required, and the lighting equipment 10
There is a problem that not only does the parts management increase but also the cost increases.

1 is provided with a through hole 34 at the center thereof,
Cord adjuster 3 for penetrating 5 and adjusting the height of lighting equipment
6 is attached.

The chassis 32 is provided with a substantially U-shaped stopper mounting portion 37 which extends in the circumferential direction and is formed by being pushed in from the outside to the inside. The U-shaped portion has a hole penetrating in the radial direction, and the cord 35
Can be inserted. Further, the stopper mounting portion 37
A screw hole 37a is formed in the center of the screw hole 42 so that the screw 42 can be fitted therein.

The cord stopper 38 has a cord 35 at one end.
Is provided at the other end, and a relatively long flat plate-shaped guide piece 40a and a distal end bent outward to have a spring action slightly shorter than the guide piece 40a. Insert 40 constituted by piece 40b
And are provided integrally. Guide piece 4 of this insertion portion 40
Holes 41, 41 are located near the center of the locking piece 40a and the locking piece 40b.
And the screw 42 is passed through.

FIGS. 4 and 5 show the switch section 16 for opening and closing the fluorescent lamps 18, 18, the glow lamp 17, and the like. The top of the switch section 16 is formed in a round shape 16a, provided with an arc rib 16b, and smoothly guides a cord 35 to be inserted into a cord adjuster 36 into the chassis 32.

The operation of inserting and attaching the cord stopper 38 of the thus-constructed hanging lighting fixture will be described.

First, the cord 35 is guided through the cord adjuster 36 of the cover 31 to the electric components inside the chassis 32. As shown in FIGS. 2 and 3, the cord 35 close to the chassis 32 is
Is held by the holding unit 39 of the above.

Next, the guide piece 4 of the cord stopper 38
Oa and the locking piece 40b are overlapped against each other against the spring action, and inserted into the hole of the stopper mounting portion 37 by the guide piece 40a. Due to this insertion, the insertion portion 40 is fixed to the locking piece 4.
