Abstract
In a fuel injection device, a pressing surface of a pressing member presses an opening wall surface to interrupt communication between an inflow port and a pressure control chamber when communication between an outflow port and a return channel is made by a pressure control valve, and the pressing surface of the pressing member is displaced and separated from the opening wall surface to open the inflow port of the opening wall surface to the pressure control chamber when the communication between the outflow port and the return channel is interrupted by the pressure control valve. One of the pressing surface of the pressing member and the opening wall surface of the control body is provided with an inflow depressed portion and an outflow depressed portion partitioned from each other, and a depressed dimension of the inflow depressed portion is larger than a depressed dimension of the outflow depressed portion.
