Abstract

PURPOSE:To adjust a position in the thrust directin of the shaft minutely by mounting the first magnet for adjusting the position in the thrust direction to the shaft and arranging the second magnet to a bearing member in the thrust direction so as to be opposed to the first magnet. CONSTITUTION:The shaft 10 is axially supported to an outer cylinder case 11 by a bearing 12, and a hollow cylindrical permanent magnet 13 for a field magnet is held to the case 11 through a holding member 11a. A rotary coil 14 is connected to the shaft 10 by a holder 15 in resin, a commutator 16 is further fixed integrally to the shaft 10, and a thrust receiving member 18 for receiving thrust in the thrust direction of the shaft 10 is screwed and mounted. The first permanent magnet 19 and the second permanent magnet 20 are mutually arranged oppositely to the shaft 10 and the thrust receiving member 18, and the directions of magnetic force of these first and second permanent magnets 19, 20 are directed in the mutually sucked or repelled directions.
