An objective of the present invention is to improve mountability of a spring. A DC motor (2), an output gear (Gf), and a speed reducing gear train (5) are formed at a case (7) configured by overlapping a housing (7) with an upper housing (30) in an axis line (Xa) of the output gear (Gf). An geared motor (1) provides an elastic force to the output gear (Gf) to allow the output gear (Gf) to be rotated in one direction around an axis line (Xa) by a spring (Sp) mounted at the output gear (Gf). The spring (Sp) includes an opposite end (Sp2) extending to an axis direction from a base on a coil, and one end (Sp1) extending to a diameter direction from the base. The opposite end (Sp2) is hooked at the output gear (Gf) from the upper housing (30). The one end (Sp1) is hooked at locking grooves (65a, 65b) formed in the upper housing (30) to stop the rotation of the spring (Sp).The locking grooves (65a, 65b) are open at the lower housing (70) side. |
