PURPOSE:To allow a vibro-preventive rubber to function both for preventing vibrations and absorbing variation in the belt tension by using No.1 surfaces of L-shaped No.1, No.2 plates as mounting surfaces, adhering No.1 rubber member between the No.1 surfaces, and adhering No.2 rubber member between the No.2 surfaces. CONSTITUTION:An L-shaped No.1 plate 1 consisting of No.1 surface 1a and No.2 surface 1b is mounted on a vibratory body by the No.1 surface 1a, while L-shaped No.2 plate 2 consisting alike of No.1 surface 2a, No.2 surface 2b is fixed to the basis by the No.1 surface 2a. No.1 rubber member 3 is interposed and adhered fast between the two No.1 surfaces 1a, 2a, while No.2 rubber member 4 between the No.2 surfaces 2a, 2b. Accordingly vibrations in different directions applied to the vibratory body are absorbed by No.1 rubber member 3, and variation in the belt tension due to displacement of the vibratory body absorbed by No.2 rubber member 4 which expands and shrinks in the direction of displacement. |
