新案登録請求の範囲第１項記載の燃料噴射装置。[Claims for Utility Model Registration] 1. A fuel injection device in which a fuel injection valve faces an intake passage whose flow rate is controlled by a throttle valve whose opening degree is variable, and the fuel injection valve is provided upstream of the throttle valve with respect to the intake air flow. In the above, the fuel injection valve is rotatably mounted, and an interlocking mechanism is provided to variably control the injection direction of the fuel injection valve in conjunction with the throttle valve opening, so that the fuel injection valve is configured to operate at the throttle regardless of the throttle valve opening. A fuel injection device characterized in that the fuel injection device is oriented toward a predetermined portion of a valve. 2. The interlocking mechanism includes a throttle sensor that detects the opening degree of the throttle valve, a motor that rotates the fuel injection valve, and a control circuit that controls the motor in accordance with a signal from the throttle sensor. A fuel injection device according to claim 1 of the utility model registration claim. 3. The fuel injection device according to claim 1, wherein the interlocking mechanism is a transmission gear mechanism that connects the throttle valve and the fuel injection valve in an interlocking relationship. 4. The fuel injection device according to claim 1, wherein the interlocking mechanism is a linkage mechanism that connects the throttle valve and the fuel injection valve in an interlocking relationship.
