<p>A valve includes a valve element (34); a valve seat (31b); a coil spring (40); and a spring bearing portion (33). The coil spring (40), provided between the valve element (34) and the spring bearing portion (33), presses the valve element (34) toward the valve seat (31b). An effective upper winding end (P of T2) of the coil spring and an effective lower winding end (Q1 of T5) of the coil spring are offset from each other by 180 degrees in a plan view.</p> |
