Abstract:
Provided is a fuel injection valve capable of quickly stopping a position of a movable element at a predetermined position after closing a valve while reducing an impact force of a valve body. Therefore, a valve body 101 includes a sleeve 113. A first movable core 201 (first movable element) lifts the valve body 101 by the attractive force of a magnetic core 107. A second movable core 202 (second movable element) further lifts the valve body 101 by the attractive force of the magnetic core 107 after the first movable core 201 (first movable element) lifts the valve body 101. After the valve body 101 is seated on the seat member 102 and the second movable core 202 (second movable element) is separated from the sleeve 113, a bottom surface 201g of the first movable core 201 (first movable element) collides with a storage bottom surface 111b (collision receiving portion).
