<P>PROBLEM TO BE SOLVED: To provide a geared motor with a new structure that is safe, compact, and more inexpensive by using a direct current motor and supplying electric power from an external power source with two-line and two-terminal. <P>SOLUTION: A geared motor includes: a load driving motor 18; and first and second switches 86, 88 and first and second diodes 96, 98 for regulating actuation displacement magnitude. The load driving motor 18 is interposed between the first switch 86 and the first diode 96, and, the second switch 88 and the diode 98 in an electric circuit. The switches 86, 88 and the diodes 96, 98 control drive, stop, and stop holding operations of the load driving motor 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
