ABSTRACT:
A playback industrial robot comprises at least one driving device provided with an electric motor having a motor shaft. The driving device comprises a reduction gear mechanism for reducing a rotational speed of the motor shaft of the motor, an output shaft for operating the robot, a clutch mechanism which is in a disengaged state when the output shaft rotates in a teaching mode so that the reduction gear mechanism does not act as a load, a mechanism for putting the clutch mechanism in an engaged state depending on supply and cutting off of the supply of compressed fluid when the teaching mode is started, and a case for accommodating the motor, the output shaft and the above mechanisms. The clutch mechanism comprises a movable clutch member applied with a rotary force depending on forward and backward rotations of the motor and guide members arranged in parallel to the output shaft at positions separated from a center of the output shaft toward an outer peripheral direction thereof. The movable clutch member is provided on the guide members so as to be non-rotatable but movable in an axial direction of the output shaft.
