<P>PROBLEM TO BE SOLVED: To ensure the closing operation of a throttle valve by the closing operation of an accelerator operating member even during a failure of a motor or the like by restraining the throttle valve of an engine from being opened exceeding the operation amount of the accelerator operating member. <P>SOLUTION: In this device for controlling opening/closing of a throttle valve of an engine, a return spring 10 for energizing the throttle valve in the closing direction is connected to the throttle valve 8 of the engine, an accelerator operating member 2 to be manually operated to open/close the valve and a motor 12 operated to automatically open/close the valve 8 are connected to each other via a three-way transmission device 11. In the device, the three-way transmission device 11 is structured such that, when the accelerator operating member 2 is operated in the closing direction of the throttle valve 8, the closing operation is transmitted to the throttle valve 8 in priority to the operation of the motor 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
