Abstract

PURPOSE: To maintain an accurate reversion preventive mechanism free from secular change through contact of a stopper for checking reversion of the rotor and specified ones of reduction gears under a given pressure by a spring member.
CONSTITUTION: A cam 11 serving a s a retaining section of checking reversion and an output pinion 12 are solidly formed on the rotor 10 while a cylinder 27 is formed on a pinion 26 integral constructed with a gear 25 to be meshed with the pinion 12. A press spring presses a stopper 22 for checking reversion through a first wheel 24 in suchf a manner the stopper 22 turns following the rotation of the first wheel. With such an arrangement, in normal rotation of the rotator 10, the first wheel 24 works to sisengage the stopper 22 and the cam 11, keeping the rotation on. In reversion thereof, the first wheel 24 is reversed so as to engage the stopper 22 with the cam 11 whereby the rotation is blocked. In this manner, it is possible to ensure accurate checking of reversion free from secular change.
