Patent abstract
If a pressure sensor is increased in size and therefore the inside diameter of a yoke is increased, a stopper is provided with a large-diameter portion. The large-diameter portion makes it possible to reduce the air gap between the stopper and the yoke and therefore suppress an increase in magnetic resistance. Besides, a magnetic circuit member is provided at an outer peripheral side of a sleeve. The magnetic circuit member makes it possible to reduce the air gap between the yoke and an armature and therefore suppress an increase in magnetic resistance.
