<P>PROBLEM TO BE SOLVED: To provide a motor with a speed reducing mechanism as an actuator wherein a long life and high reliability can be obtained, the initial setting of its output shaft and the detection of its rotation position can be made, and size and cost reduction can be implemented. <P>SOLUTION: An annular magnet (16) is attached to a worm gear (10) fixed on a motor rotating shaft (22c) with a yoke (17) in-between. A Hall IC (31) is mounted on a line that is perpendicular to the plane of a substrate (21) and orthogonal to the motor rotating shaft (22c). A Hall IC (32) having a lead portion (32a) is disposed and mounted at an open angle of 90 degrees to the Hall IC (31) by a holder (34) with its body (32c) at a distance from the substrate. The annular magnet is magnetized so that its number of poles is odd within the range of 180 degrees of its circumference. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
