To lower the cost for connecting a power transmitting cable and an input and an output members.

In the structure for connecting a throttle cable 20, which has a cable side connector 21 in an end thereof, and a diaphragm plate 10 having a connector insertion hole 12, in which the cable side connector 21 of the throttle cable 20 is passed, and a connector receiver 14, which is continuously formed to the connector insertion hole 12 and which is to be engaged with the cable side connector 21, the diaphragm plate 10 is provided with a stopper 30 to be inserted into the connector insertion hole 12 so as to reduce an opening area of the connector insertion hole 12 in comparison with an area required for passing of the cable side connector 21 so as to regulate the movement of the cable side connector 21 from the connector receiver 14 to the connector insertion hole 12.
