Abstract
A fuel injector includes a body, a main valve body, a sub valve body, an electric actuator, and a valve-opening force transmission mechanism. The body houses a main passage through which fuel flows to an injection, and a sub passage branched from the main passage and through which the fuel flows to the injection port. The main valve body opens or closes the main passage, and the sub valve body opens or closes the sub passage. The electric actuator applies a valve-opening force to the sub valve body. The valve-opening force transmission mechanism transmits the valve-opening force of the sub valve body to the main valve body to open the main valve body in a condition that a valve-opening stroke of the sub valve body is greater than or equal to a predetermined amount.
