Shows the rear wheels. The rear wheel W _b is configured similarly to the front wheels W _f.

Reference numeral 1A indicates a fender portion, which includes the fender 1 and
The mounting portion 2 located on both sides of the fender 1 is composed of a mounting member 4 having one end mounted with a bolt 7 and a nut. Then, the attachment member 4 is attached to the rear fork F _b with the attachment portion 5 at the other end using the bolt B and the washer A. In addition, the generator 1 is attached to one of the mounting members 4.
An attached portion 6 for attaching 1 is provided on the outer side opposite to the rear wheel W _b .

The generator 11 described above is rotatably attached to the attached portion 6, and a dynamo roller 12 is provided by a coil spring (not shown) provided between the generator 11 and the attached portion 6. Is urged so as to come into pressure contact with the side surface of the tire t. Reference numeral 31 denotes a rear light as a light emitting device, and a casing 32 mounted on the fender 1
And a semi-transparent reflection plate 33 attached to the opening of the casing 32, and although not shown, a light-emitting diode arranged in the casing 32 to supply light to the reflection plate 33, a white miniature light bulb, etc. Although not shown in the drawing, the light source is connected to a light source and a power supply line that connects the light source to the generator 11.

Next, the operation will be described. When the rear wheel W _b rotates by running the bicycle, the tire t
Since the dynamo roller 12 is in pressure contact with the side surface of the, the power is supplied from the generator 11 to the light source of the tail lamp 31 by rotating the dynamo roller 12, and the light source is turned on.
Then, the light from the light source that is turned on enters the reflection plate 33 and is emitted in a diffused state from the reflection plate 33.
It is possible to notify the existence to the rear of the running and confirm the existence.

As described above, according to the second embodiment, the same effect as that of the first embodiment can be obtained. Then, the tail lamp 31 reflects light on the reflector 33, and
Since the light from the light source is diffused by the reflection plate 33, the light can be clearly seen even from the diagonally rear side, so that the safety can be improved.

In the above embodiments, the dynamometer roller 12 is pressed against the side surface of the tire t.
By pressing the dynamo roller 12 against the side surface or the peripheral surface of the rim r, it is possible to prevent the dirt and the like adhering to the tire t from adhering to the dynamo rotor 12 and causing the dynamo roller 12 to malfunction.
