摘要

A dial communication system of a steering wheel of an automobile includes a steering wheel having an annular frame, and a dial communication device mounted on the annular frame of the steering wheel and having a dialogue member and a dial member each secured on the annular frame of the steering wheel. In such a manner, the dial communication device is installed on the steering wheel so that a driver's one hand holding the steering wheel can synchronously operate the dialogue member and the dial member of the dial communication device to perform functions of dial and dialogue.
