A guard holder 4, which is a collar-shaped member, is attached to one end side (upper end side in FIG. 1) of the. In this case, the cylindrical insertion portion 4a protruding from the lower end of the guard holder 4 is screwed into the threaded portion formed on the inner peripheral portion on one end side of the case 1. A handle portion 5 is integrally formed on the other end side (lower end side in FIG. 1) of the case 1. Also,
A light bulb guard 10 is fixed to the guard holder 4 with a horizontal wire rod 6 and a vertical wire rod 7 combined in a grid pattern, and ring members 8 and 9 fixed to the upper and lower ends of the light bulb guard 10. Further, a light bulb cover 11 made of, for example, transparent glass is attached by screwing to a cylindrical receiving portion 12 projecting from the upper part of the guard holder 4 in FIG. 1 so as to cover the light bulb 2. A packing 13 is interposed between the tip of the light bulb cover 11 and the guard holder 4.

A switch 14 is integrally formed at the lower end of the socket 3, and a rod-shaped operator 15 is provided on the switch 14 so as to project in the left-right direction in FIG. This manipulator 15 can be moved in the left-right direction in the figure. Here, the cylindrical wall portion of the case 1 is formed with through holes 1a, 1a corresponding to the operation element 15 and through which the operation element 15 is inserted. A cord wire 16 is connected to the terminal of the switch 14.
The cord wire 16 passes through the partition wall portion 1b formed inside the case 1, passes through the inside of the handle portion 5, and is led out to the outside from the lower side of FIG. A packing 17 is provided in a penetrating manner in the upper part of the partition 1b of the cord wire 16 in FIG. 1, and an annular pressing member 18 is screwed to the case 1 so as to press the packing 17.

A waterproof cover 19 having a cylindrical shape, for example, a cylindrical shape is attached to the outer periphery of the case 1. The waterproof cover 19 is made of a soft material such as rubber, and has O-ring-shaped seal portions 19a and 19b integrally formed at both ends thereof, and a hollow portion which allows the operator 15 to project from the upper portion in FIG. Shaped projections 19c and 19d are integrally formed. here,
An annular groove 4b is formed outside the cylindrical insertion portion 4a on the lower surface of the guard holder 4 in FIG.
When the guard holder 4 is attached to the case 1, the upper end of the case 1 is inserted into the groove 4b so that a predetermined gap is formed between the upper end surface and the groove 4b. Then, the seal portion 19a of the waterproof cover 19 on the guard holder 4 side is sandwiched in the gap. In this case, the size of the gap is set so that an appropriate pressing force is applied to the seal portion 19a, and when the case 1 is screwed into the guard holder 4, as shown in FIG.
