<P>PROBLEM TO BE SOLVED: To provide a geared motor with an optical detector which can be fixed easily. <P>SOLUTION: The geared motor comprises a resin gear case 21 containing a reduction gear train 22 for reducing rotation of a motor shaft 10a, a resin inner lid 25 for closing the gear case 21, a resin end lid 230 being fixed onto the inner lid 25 and containing a substrate 34 mounting a photointerrupter 33 for detecting rotation of an output shaft 20a projecting from the inner lid 25, and a forked hook 231 having a pawl F at each distal end of a pair of legs 231b, 231b bent integrally from the opposite sides of a coupling portion 231a. The end lid 230 integrally has anti-tilt portions 35f and 35g for regulating the substrate 34 to erect with respect to pawl engaging portions 35e, 35e and an end plate 35 on the side of the end plate 35 opposing the inner lid 25, wherein the pawl engaging portions 35e, 35e engage with the pawls F, F and the coupling portion 231a retains the edge of the substrate 34 on the counter end plate side. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
