Filed: 1987-04-24
Abstract: PURPOSE:To make an open-circuit voltage large by shifting a rocking supporting point of an armature toward the other end of a yoke before the armature touches the other end of the yoke. CONSTITUTION:When a coil 14 is energized, an armature 13 rocks with the end of a yoke 12a being a rocking supporting point so that a magnetic pole part 13a of the armature approaches a head part of an iron core 11a. The armature 13 begins to move and contacts with a bump 12c before it touches the head part 11a of the iron core. When the rocking supporting point of the armature 13 is transferred to the bump 12c from the end of the yoke 12a, the end of the yoke 12a and the one end of the armature 13b begins to be detached from each other. Thereupon, magnetoresistance between the yoke piece 12 and the armature 13 increases and a distance between the rocking supporting point and an attraction plane decreases.
