Abstract
A dial device for a steering wheel of an automobile includes a steering wheel having an annular frame, and an annular film keyboard tightly mounted on the annular frame of the steering wheel and having a connecting terminal connected to a wireless emitter so that the annular film keyboard supplies a pressing dial signal which can be transmitted to a main processor through the wireless emitter in a wireless transmission manner. In such a manner, the annular film keyboard co-operates with the steering wheel so that a driver can hold the steering wheel and can press the annular film keyboard so as to dial synchronously, thereby achieving a dial function.
