<p>PROBLEM TO BE SOLVED: To improve the visibility of the presence of an automobile, etc., and to prevent the light from being emitted when unnecessary by providing a light emission part having a switch side light-emitting body terminal one end of which is connected to a light emitting body and the other end of which is connected to an energization part. SOLUTION: A light emitting body 1 for accessory is fitted by screwing a fitting part 5 to an air valve 20 of a wheel of a bicycle, a motorcycle, an automobile, etc. When the wheel fitted with the light emitting body 1 for accessory is started to rotate, a weight 10 is moved to an energization part 4 by the centrifugal force to bring a contact part 11 into contact with the energization part 4, the light emitting body 16 is energized by a cell 7 through an expandable body 9, the contact part 11, a fitting body 2, a cap body 13a and a switch side light emitting body terminal 19 to emit the light from the light emitting body 16. When the wheel fitted with the light emitting body 1 for accessory stops, the effect of the centrifugal force on the weight 10 is eliminated, the contact part is detached from the energization part 4 by the restoring force of the expandable body 9, the energization to the light-emitting body 16 is disconnected to complete the light emission of the light emitting body 16.</p> |
