Abstract
Two or more target points different in amplitude in a natural mode, which exist in a housing of an object to be damped such as an engine, a gearbox, motors, or the like are located. Among these target points, an arm is fixed at a position relatively small in amplitude, and a vibration absorber provided at the free end of the arm is pressed against a position (relatively large in amplitude. When vibrations occur in the object, the vibration absorber holds the target point relatively large in amplitude while the arm is following the vibrations of the target.
