摘要： A valve includes a valve element; a valve seat; a coil spring; and a spring bearing portion. The coil spring, provided between the valve element and the spring bearing portion, presses the valve element toward the valve seat. An effective upper winding end of the coil spring and an effective lower winding end of the coil spring are offset from each other by 180 degrees in a plan view.

摘要： A fuel pressure adjusting apparatus which includes a casing which includes a fuel introduction port, and a fuel discharge port; and a cylindrical member which is housed in the casing, and which includes a valve seat at an end portion thereof, and a communication passage therein, the communication passage connecting the fuel introduction port to the fuel discharge port; a valve element which is provided on a fuel discharge port-side of the valve element in the casing, and which closes the communication passage when the valve element is seated on the valve seat; and a leaf spring which is provided at the fuel discharge port, and which applies force to the valve element in a direction toward the valve seat. The leaf spring includes a concave portion which supports the valve element, and which is formed such that there is a gap between the concave portion and the valve element.
