A decoupling device for gear motors used in cargo conveyor belt systems in which a coupler member is free to move axially on the output shaft of the gear motor to cooperate with the final gear of the gear train in the motor housing. A spring member maintains the coupler in engagement with the final gear via the corresponding jaw structures. Disengagement of the respective jaw structures is accomplished by axially moving the coupler member along the output shaft by means of a self-securing pivotally mounted yoke which engages the coupler for transmitting axial motion thereto. The yoke is pivoted by means of a cam follower device mounted for pivotal movement exteriorly of the gear housing to thereby rotate to one of two positions, thus connecting or disconnecting the aforementioned respective jaw structures on the output shaft.
