PURPOSE:To make stop motion secure as well as to facilitate the release of an intermediate stop so easy, by stopping an output shaft at the specified intermediate stopping position in a way of engaging an engaging pin of a rotary body with an engaging hole of a fixed body. CONSTITUTION:An engaging hole 21 in a fixed body 18, and an engaging pin 22 is slidably installed in a rotary body 11, then a sliding pin 20 is installed in the engaging hole 21 of the fixed body free of slide motion. With this constitution, thus the engaging pin 22 is engaged with the engaging hole 21 whereby an output shaft 2 is stoppable at the specified intermediate sopping position and, what is more, engagement between the engaging pin 22 and the engaging hole 21 is releasable free with the sliding pin 20 driven, so that stop motion is made securable, while the release of an intermediate stop is easily performable.
