Abstract
A fuel pressure controller used in a fuel supply device of an automobile has an open-close ball insertion groove formed to be protruding from a side of a valve pressing member. The valve pressing member has a predetermined open area in a circumferential direction and in a radial direction to prevent separation of an open-close ball even at the time of an operation, such that pressure may be accurately controlled and noise may be reduced.
