る燃料噴射装置用スロツトルボデイ。[Claims for Utility Model Registration] A fuel having an injection valve that injects fuel into an intake passage installed in the body, and an air valve and a throttle valve provided on the upstream and downstream sides of the intake passage, respectively. In the throttle body for an injection device, the air valve is biased in a closing direction by a spring means, and is driven by a negative pressure actuator that responds to negative pressure in the intake passage between the air valve and the throttle valve. The negative pressure actuator is driven to open the throttle valve, and the negative pressure actuator is located along a line substantially orthogonal to a substantially central portion of the valve shaft of the throttle valve, and also slightly upstream of the throttle valve when the throttle valve is fully closed. A throttle body for a fuel injection device, characterized in that the throttle body is connected to a negative pressure take-out port that opens at a position.
