Vibration-damping device of motor

The utility model provides a vibration-damping device of motor, comprising a motor end cover which is provided with a convex connecting portion with gear-type outer diameter and a rubber shock absorber with a gear-type inner diameter corresponding to the outer diameter of the convex connecting portion. The rubber shock absorber is connected with the motor end cover through the convex connecting portion. An end face of the rubber shock absorber is provided with a location mark, and the motor end cover is provided with a location marking boss corresponding to the location mark. Employing the technical proposal, the vibration-damping device of motor thoroughly resolves slide problems caused by abrasion damage between the rubber shock absorber and the motor end cover, thereby producing more significant vibration-damping effect and better motor stability. The corresponding location mark on the end face of the rubber shock absorber and the location marking boss on the motor end cover avoid dislocation of front and
