Abstract

A power transmitting device especially suitable for use in photocopying machines includes a driving shaft and a driven shaft. When locking members on the respective shafts are axially disengaged from each other, the driven shaft and the driving shaft are rotatively displaced with respect to each other by a predetermined angle so that the locking members may be freely and positively locked when the driving shaft and driven shaft are axially reengaged.
