The invention reduces the shift shock of a device equipped with a plurality of prime movers, and provides a power transmission device of a device having a first prime mover (engine) 1 and a second prime mover (motor) 2 as drive sources, which is arranged so that in the process of shifting from the first speed stage to the second speed stage, the increase or decrease in the rotation speed of the first prime mover (engine) 1 is the reverse of the increase or decrease in the rotation speed of the second prime mover (motor) 2. Also, in the process of shifting from a first speed stage to a second speed stage, control is performed so that a torque, which cancels out the inertia torque of one prime mover (engine) 1, is output by the other prime mover (motor) 2. <IMAGE> |
