It is designed to be tightened and fixed to the screw hole 8 of the left side wall 4a via the rib 23. 25a, 25b are upper and lower first stopper ribs protruding from the front upper and lower bottom surfaces of the hollow body 20a of the side eye 20, and grooves 26, 26 are cut out in these first stopper ribs 25a, 25b. are doing. 27a and 27b are this side eye 20
The upper and lower second stopper ribs protrude from the upper and lower bottom surfaces of the central portion of the hollow body portion 20a.
The locking rib 27b also serves as the external portion of the screw-locking cylinder 23.

Reference numeral 28 denotes a sub-bowl-shaped reflective plate housed in the side eye 20, and the upper and lower first stopper ribs 25a, 2
Peripheral flange 28 fitted into grooves 26, 26 of 5b
a and a first sub-socket 29 in the central hole.
The first sub-light bulb 30 is fixed through a Electrical connections can be made to the secondary socket 29 and the tail terminal of the first secondary bulb 30.

31 is a resin reflector housed in the side eye 20, which includes a front reflective surface 32a and a rear reflective surface 32.
b. It has a side reflective surface 32c, a light bulb insertion hole 32d, and the upper second stopper rib 27 on the upper side.
The light bulb insertion hole is provided with a groove 33 into which the light bulb insertion hole 33 is inserted, and a recess 34 on the lower surface into which the lower second stopper rib 27b engages. 32d, a second sub-light bulb 35 is fixed via a second sub-socket 36, and the sub-light bulb 35 facing the opening 5 with the resin reflector 31 housed in the side eye 20. The lead plate 18 and the sub-ground lead plate 17 are adapted to be electrically connected to the second sub-socket 36 and the tail terminal of the second sub-bulb 35.

A sub-bowl-shaped reflector plate 28 is provided within the side eye 20.
To attach the peripheral flange 2 of the sub-bowl-shaped reflective plate 28,
8a into the first stopper ribs 25a, 25b,
and the sub-lead plate 18 and the sub-earth lead plate 1.

The side eye 20 serves as a secondary illumination, but these first or second
By wiring the secondary light bulbs 30 and 35 separately from the main light bulb 10 and using a switch for indicating left and right direction, the side eye 20 can be used for indicating left and right direction, or by using a flashing device, the side eye 20 can be used as a flash light. It can also be used as

(F) Effects of the Invention Since the bicycle headlamp of the present invention is constructed as described above, both the resin reflector and the sub-bowl-shaped reflector can be housed in the side eye, and in this case, Since the lead plate and the sub-earth lead plate can be used in any case, it is possible to provide a highly versatile product at a low cost that meets the needs of the market. Furthermore, according to the present invention, since the side eye has a first stopper rib for fixing the sub-bowl-shaped reflector and a second stopper rib for fixing the resin reflector, these sub-eyes have a first stopper rib for fixing the sub-bowl-shaped reflector and a second stopper rib for fixing the resin reflector. Attachment of the bowl-shaped reflector or the resin reflector can be carried out extremely easily, and the assembly work efficiency can be improved.
