PROBLEM TO BE SOLVED: To provide radio equipment having a circuit board, on which a transmission circuit is mounted, built in a hub dynamo, and facilitating work of connecting an antenna to the circuit board.SOLUTION: Radio equipment comprises a circuit board 48 that is received inside a hub dynamo 1 and is mounted with electronic components 54 forming a transmission circuit, and antenna wiring 64 connecting, for connecting a light 40 operated with electric power generated by the hub dynamo 1 to the hub dynamo 1, a first light side code 38 arranged outside of the hub dynamo 1 to the transmission circuit of the circuit board 48. With this, the first light side code 38 functions as an antenna. When the light 40 and the hub dynamo 1 are connected through codes 38, 46, 74, 76 for allowing the electric power generated by the hub dynamo 1 to be supplied to the light 40, this means that the circuit board 48 in the hub dynamo 1 is connected to an antenna. Accordingly, work of connecting the antenna to the circuit board 48 is facilitated.SELECTED DRAWING: Figure 1 |
