の穴が設けてある。 A slight gap is formed between the outer circumferential surface of the holding frame 10 and the inner circumferential surface of the case 18 so that the outer diameter of the tip bent portion 14 of the projection piece 13 fits into the inner circumferential surface of the case 18. Therefore, as shown in FIG. 3, a middle step part 22 is formed on the outer circumferential surface 3 of the transparent lid body 2, and the middle step part 22 is connected to the rear surface of the flange part 6.
The outer circumferential surface of the case 18 is adapted to fit into the inner circumferential surface of the ring-shaped protrusion 17 of the case 18. Also transparent lid body 2
Engagement steps 23 are formed on both sides of the inner surface of the cylindrical holder 20 on the rear surface of the engagement steps 23.
The front edges of the two are in contact with each other. A partition plate 24 for blocking external light is provided inside the plastic holder 20, and an aperture hole 25 is provided in the center of the partition plate 24 so as to coincide with the optical axis. In the rear part of the holder 20 from the partition plate 24, a photoelectric element insertion hole 26 is formed by narrowing the inner diameter to match the outer diameter of the photoelectric element 7. A recessed step 28 into which the flange 27 of the photoelectric element 7 fits is formed, and the photoelectric element 7
The flange portion 27 is held between this concave stepped surface and the bottom surface of the holding frame 10. The cap 29 attached to the rear end opening of the case 18 has a cord insertion hole 31 for pulling out the cord 30 and an LED for the power pilot.

を防止する効果がある。(f) Effect of the invention According to the invention, the photoelectric element is held between the holder and the holding frame, and the holding frame and the holder are securely attached to the transparent lid body through the protrusion formed on the inner peripheral surface near the front end of the case. Therefore, no special work is required to align the optical axes of the lens of the transparent lid body and the photoelectric element, and the holding frame and the transparent lid body can be combined by simply pushing them into the case. It has the advantage of being easy to perform, and the front edge of the outwardly bent portion of each protruding piece of the holding frame slides against the inner surface of the case and rides on the gentle slope of the protrusion, deforming elastically and becoming smoothly transparent. It engages with the lid and has the effect of preventing wobbling due to dimensional tolerances between the holding frame/case and the transparent lid.
