PURPOSE: A vibration-proof hanger with a spring-constant control function is provided to enable an appropriate number of elastic plates to be stacked depending on load support ability and vibration-proof level. CONSTITUTION: A vibration-proof hanger with a spring-constant control function consists of a casing(1), elastic plates(2), load spread plates(4), and a hanger rod(3). One side of the casing is open, and a through hole is formed on the opposite side to the open side of the casing. The elastic plates are stacked in the casing in plural layers. If the elastic plates bear load, they are deformed in proportion to the load. The load spread plates are respectively inserted into between the top of the elastic plate and the elastic plates. The head of the hanger rod hangs on the load spread plate of the top of the elastic plate. The end of the hanger rod is exposed through the central holes of the load spread plates and the elastic plate and the through hole of the casing.
