PROBLEM TO BE SOLVED: To prevent a flaw and breakage or the like generated by vibration by absorbing and moderating instantaneously as much as possible vibration of a carriage generated by a floor applied mainly with a grating treatment. SOLUTION: In this vibration-controlled carriage, an isolator 20 in which a rope body bundled and threaded with several hard steel wires is wound spirally, in which a spring is formed by arranging a fixing frame plate parallel to its wound direction, and which absorbs vibration with frictional heat generated by spring action is arranged in one part of the carriage 10 for conveying a precision product, parts and the like. A ratio of a natural frequency (fn ) of the isolator 20 to an estimated frequency (ft ) generated by the carriage traveling on a floor surface applied with a grating treatment or the like is set to satisfy ft /fn >√2.
