A spherical part(11) is formed along the circumference of an injector's ejecting part, and a rack(5) is engaged with a gear(3) fixed at the axle of a step motor(1). And a carriage(9) includes a moving boss(10) which is connected with the rack, and a slot(6') guiding a boss(10) is formed on a guiding rail(6). When the engine is running, as an engine control unit(ECU2) senses a swirl in the lean burn engine which is on working, the step motor(1) starts up by the sensor signal. Thus the rack engaged with the gear(3) makes a linear movement, then, the fixed boss(10) of the carriage(9) moves left and right along the slot(6') of the guiding rail. Consequently the injector(4) moves left and right and adjusts the ejecting angle suited to the air movement.
