An operation mechanism comprises an input shaft connected to a first resilient member for storing and releasing energy required for reciprocal movement of a drivable member and an output shaft connected to a second resilient member for storing and releasing energy required for returning the drivable member. The ends of both shafts are coaxially facing and a clutch for interlocking the ends of the shafts with a free rotation for a half turn is formed and an output rod connected to the output shaft is reciprocally moved during an intermittent movement of the input shaft and the output shaft for about a half turn in a specific direction.
