Abstract

PURPOSE:To realize the miniaturization of a magnetic circuit and to make the magnetic performance high by providing plural plates arranged so as to pinch a magnet, and providing a magnetic gap between these plates. CONSTITUTION:Under a magnet 7, a plate 8 is joined, and on the magnet 7, a plate 9 and a plate 10 are coupled in the vicinity of the center and in the vicinity of the outer periphery, respectively, and between the plate 9 and the plate 10, a magnetic gap 11 is provided. In this state, the magnet 7 reverses the magnetizing directions in the vicinity 7a of a magnet center and in the vicinity 7b of the outer periphery.
