An anti-vibration apparatus for actively damping an object vibrations by generating control forces for reducing the vibrations includes a first actuator for generating a first control force, and a second actuator which generates a second control force and is driven on a driving principle different from that for the first actuator. The carrier is prepared by the steps comprising: preparing an initial mixture including a diamond and a non-diamond by means of explosion of a detonating agent; subjecting the initial mixture to an oxidation treatment to obtain a suspension solution including the diamond; and separating a phase including the diamond. The shield is adapted to be disposed above the roadway surface vertically depending from the vehicle and spaced rearwardly from the vehicle wheel in a plane extending transversely to the vehicle. Each infrared temperature sensor is positioned proximate to a respective vessel mounting site to receive infrared radiation emitted by media contained in a vessel mounted at the vessel mounting site, and is configured to transmit a measurement signal indicative of the temperature of the media. The low rigidity section elastically supports a periphery of the inwardly protruding section due the low rigidity section having a lower rigidity than the inwardly protruding section.
