Abstract
An air-pressure vibration-damping apparatus, supporting an upper apparatus between a mounting floor and the upper apparatus. The vibration damping apparatus has four or more air springs for supporting the upper apparatus, a vibration-damping controller for controlling inner air pressures of the air springs so as to damp vibration from the mounting floor to the upper apparatus and suppress vibration of the upper apparatus, and a communicating pipe passing air between at least one couple of the air springs. When the couple of air springs mutually connected via the communicating pipe are regarded as one air spring, the number of air springs is three. Regarding this couple of air springs, the vibration-damping controller controls air pressure of at least one air spring.
