PROBLEM TO BE SOLVED: To provide a fluid sealing type compliance bush for a suspension capable of advantageously improving riding comfortableness since a predetermined damping effect can be stably provided by high damping characteristics when vibrations such as flatters and brake vibrations of normal magnitudes are input therein and low spring characteristics can be provided at the initial stage when the bush starts to be deflected by the input of an impact load into a wheel. SOLUTION: One-way valve means 56, 74 are installed in a short-circuit flow passage 84 allowing a first fluid chamber 78 to communicate with a second fluid chamber 80. When an impact load from one to the other direction in the longitudinal direction is input into a wheel, a larger flow resistance is developed by the one-way valve means 56, 74 in the fluid flow direction from the second fluid chamber 80 to the first fluid chamber 78 than in the fluid flow direction from the first fluid chamber 78 to the second fluid chamber 80 which is produced in the short-circuit flow passage 84.
