Abstract
The invention relates to a rotating mechanism of a throttle valve for a fuel supply device of an internal combustion engine. The mechanism has an actuator for opening the throttle valve upon depressing of an accelerator, a cam lever pivotally secured to a throttle shaft and having a cam set to open the throttle valve more than the movement of said actuator upon depressing of the accelerator, a throttle lever for coupling the cam lever to the throttle shaft, and an engaging member mounted at the cam lever side to take an engaging position or a nonengaging position of the throttle lever. In this rotating mechanism of the throttle valve, the engaging member can operate to take the engaging position with respect to the throttle shaft when the actuator becomes impossible to operate. Thus, the rotating mechanism can operate the throttle valve by the operation of an engaging member to take an engaging position or nonengaging position of a throttle lever having a cam set to open the throttle valve more than the movement of an actuator of a stepping motor or a DC motor for opening the throttle valve in response to the depression of an accelerator without using the actuator even if the stepping motor or the DC motor becomes defective to cause the throttle valve to become impossible to operate. The invention thus allows the vehicle to travel and to accelerate the increase in an air amount by opening the throttle valve more than the movement of a stepping motor as an actuator by the cam lever particularly when the vehicle is necessary to be abruptly accelerated in case like racing thereby preferably accelerating the vehicle.
