PROBLEM TO BE SOLVED: To provide a rearward alarm device of a bicycle capable of preventing the safety of a bicycle from deteriorating during running.SOLUTION: A rearward alarm device of a bicycle includes a vehicle approach detection part 21 for detecting the existence of a vehicle approaching from behind a bicycle, an information processing part 22 for processing information from the vehicle approach detection part 21, and an alarm part 23 for issuing an alarm to a driver of the bicycle. A dynamo 8 for generating power by the rotation of a wheel (a front wheel) is provided in the bicycle, and the dynamo 8 supplies power to the vehicle approach detection part 21, the information processing part 22 and the alarm part 23. Consequently, it is prevented that the rearward alarm device cannot be driven because the power storage amount of a battery is consumed during running as in the case of supply power with the battery.SELECTED DRAWING: Figure 3

    【課題】走行中に自転車の安全性が低下することを防止できる自転車の後方警報装置を提供する。【解決手段】自転車の後方から接近する車両の存在を検出する車両接近検出部21と、この車両接近検出部21からの情報を処理する情報処理部22と、自転車の運転者に警報を発する警報部23とを備えた自転車の後方警報装置であって、車輪(前車輪)の回転により発電するダイナモ8が自転車に設けられ、ダイナモ8から車両接近検出部21、情報処理部22および警報部23に給電される。これにより、電池で給電する場合のように走行中に電池の蓄電量が消耗して後方警報装置を駆動できなくなることを防止できる。【選択図】図3
