PROBLEM TO BE SOLVED: To provide an engine vibration-proof structure for a working machine, capable of suppressing the generation of noise through the collision of a retainer of a vibration-proof mount and a mounting part of the engine at working. SOLUTION: The engine vibration-proof structure for the working machine includes a restriction means for restricting the movement of retainers 20d, 21d in a direction along the upper surface and the lower surface of an engine support bracket 10 on the abutment portion of the upper surface of the engine support bracket 10 and the retainer 20d of the upper vibration-proof mount 20 and an abutment portion of the lower surface of the engine support bracket 10 and the retainer 21d of the lower vibration-proof mount 21. The restriction means comprises projections 20d1, 21d1 provided on the vibration-proof mounts 20d, 21d for forming the abutment portion; and recesses 10b, 10c provided on the upper surface and the lower surface of the engine support bracket 10 and engaged with the corresponding projection of the projections 20d1, 21d1.
