PROBLEM TO BE SOLVED: To provide an engine vibration control device in which vibration control performance of an engine is improved. SOLUTION: A material whose spring constant is lower than that of conventional vibration control rubber 105 is used for V type vibration control rubber 201. The tilt angle of a slope 221 is set so that a Z shaft of the V type vibration control rubber 201 intersects with an engine crankshaft. When tension is applied to a V belt 28, transverse tensile force is exerted to a V pulley 27. At this time, both ends of the retaining member 207 are metal-touched onto the wall surfaces 217a and 217a of a stopper 217, thereby preventing deviation of the position to a machine base 11 of an engine 9. Therefore, the clearance between a movement blade 1 and a fan case 5 can be made minute and even the position of the center shaft of a fan case 5 and a driving shaft 7 is not deviated, thus improving and stabilizing the ventilation performance.
