PURPOSE:To make the release of automatic speed governing ever so easy, by installing a release signal generating device which actuates when an accelerator grip is restored in time of the automatic speed governing, while releasing a driving device regulating fuel injection quantities by means of actuation of the said generating device. CONSTITUTION:When an automatic speed governor is set at the specified running speed, a vacuum pump 24 actuates in motion and simultaneously a suction pressure actuator 10 is operated by a control unit 22. With this constitution, a cable 11a is pulled to some extent whereby a slider 13 of an actuating device 9 being shifted to the specified position by an open operating power transmitting device 5 interlocking an accelerator grip 2 is engaged thereat by an engaging part 11c at the tip of the cable 11a. And, an on-off device 4 of a carburetor 3 is kept up in the specified opening. Next, when the grip 2 is restored under this automatic speed governing condition, a cable 5a of the said device 5 is pulled toward a closing direction by a close operation transmitting device 6, while a contact of a release signal generating device 17 is opened and thereby an atmospheric blow-off valve is opened, thus an automatic speed governing state is released free. |
