Abstract
A vibration damping construction, which is useful when it is applied to a vibration isolation washer or a pressed construction such as an oil pan, a ventilation buffle plate, etc. for an automobile, is disclosed, which is so constructed that raw materials, in each of which a rubber visco-elastic layer or such layers is or are disposed on one or two surfaces of a metal plate, are laminated on each other, so that rubber visco-elastic layers are opposite to each other, and adhered to each other to form a laminated body; rectangular pawls are formed on the raw material at the uppermost layer and the laminated body; rectangular cut-off windows, with which the cut and raised pawls can be engaged, are formed in the raw material at the lowermost layer; and these are laminated on each other and bound in one body by spot connection by means of the pawls.
