PROBLEM TO BE SOLVED: To provide a speed reducer capable of arbitrarily and simply changing a position of a torque arm in an ex-post manner.SOLUTION: In a gear motor 100 including a speed reducer 20, an intermediate shaft 40 is pivotally supported by a first bracket side bearing 30 provided in a first bracket 24 and a second bracket side bearing 34 provided in a housing 22. Since the second bracket 26 only includes a bearing 38 for a final output shaft for pivotally supporting a final output shaft 50, the direction of the second bracket 26 can be rotated arbitrarily around a shaft center of the final output shaft 50, and a position of a torque arm 28 provided in the second bracket 26 can be arbitrarily and simply changed in a circumferential direction of the final output shaft 50 in an ex-post manner.SELECTED DRAWING: Figure 1 |
