An injector is provided to maintain the closure of valve for a long time by cooperating two valve springs when the valve is closed. An injector comprises a valve body(40) of an opening closing valve(4A) pressed to the valve closing direction with a valve spring. The valve spring pressurizes the valve body to the valve closing direction. The two valve springs cooperate together in order to maintain the closure of valve when the valve is closed. One of two valve springs is a leaf spring(6A) installed to the stroke direction of the valve body at a right angle. The other valve spring is a coil spring(7) installed along the stroke direction of the valve body. |
