The disclosure is of a passive vibration isolator for reducing the transmission of vibratory displacements and forces from a vibrationally excited base or body to an isolated body. The excited body is one which may vibrate in three orthogonal directions either independently or simultaneously. The isolated body is connected with the excited body by a spring means which statically supports it and permits the excited body to move resiliently relative to it in the three orthogonal directions. Also, between the excited body and the isolated body are two weighted levers which are so pivotally connected to the bodies and to one another as to produce inertial forces which counteract the forces produced by the vibrations of the excited body and thereby reduce, in all three directions of relative movement, the vibratory forces transmitted to the isolated body from the excited body.
