PROBLEM TO BE SOLVED: To satisfactorily keep a riding comfortableness on a vehicle by preventing a body from being deformed even if the temperature of fluid is varied when an impact force on the body is relieved by using the fluid. SOLUTION: A reinforcement brace 18 comprises a piston 37 inserted into a cylinder tube 27 to divide the inside of the cylinder tube 27 into a first chamber 35 and a second chamber 36, a piston rod 38 projected from the piston 37, a gas pressure supply means 47 for transmitting the pressure of gas 46 stored in a gas storage chamber 45 to liquid 43 in the second chamber 36, a spring 48 for energizing the piston 37 to resist the pressure A of the liquid 43 in the second chamber 35 to position the piston 37 at a 'neutral position' by the energization force B of the piston 37, and an energizing force variable means 62 varying the magnitude of the energizing force B of the spring 48 according to a variation in the temperature of the gas 46 when the temperature of the gas 46 varies to hold the piston 37 at the 'neutral position'.
