ABSTRACT:
An anti-vibration device for a motor bearing at least comprises an axial barrel core, a shaft and a shock retard piece. The axial barrel core has a recess at the bottom thereof with the recess having a flat top. A bearing is received in the axial barrel and the shock retard piece is placed on the top of the recess so that a space is formed between the shock retard piece and the recess available for the shock retard piece being deformed. The shaft is movably attached to the barrel core to contact with shock retard piece. When the shaft rotates, vibration can be retarded to allow the shaft providing a steady rotation by way of support of the shock retard piece.
