Beschreibung
Zusammenfassung:	A self-holding electromagnetic valve includes: a solenoid having a tubular guide part having the same center as a central axis extending in an axial direction; a axially movable element located radially inside the guide part; a cover housing the solenoid and the movable element, having a hole portion, and made of a magnetic material; a pin located at the hole portion and movable along with movement of the movable element; and a valve section provided outside the cover and opened/closed along with movement of the movable element and the pin. The solenoid has a cylindrical part with an inner circumferential surface that receives the guide part, tooth parts that extend radially outward from the cylindrical part and are made of a magnetic material, bobbin parts provided each tooth part, and coils wound around the bobbin parts.
