PROBLEM TO BE SOLVED: To provide a fluid pressure circuit capable of changing damping characteristic. SOLUTION: This fluid pressure circuit C connected to an expandable body 1 is provided with a main damping force generating element 25 provided in a main flow passage 10 for connecting the expandable body 1 with a reservoir tank T, at least one or more auxiliary flow passages 11 for connecting the expandable body 1 with the reservoir tank T, and an opening and closing valve 40 and an auxiliary damping force generating element 26 provided in the auxiliary flow passage 11. The opening and closing valve 40 is energized from one end side and is set to a normally opened type, and a pilot flow passage 42 for leading pressure on the upstream side as pilot pressure from the opening and closing valve 40 in the auxiliary flow passage 11 is connected to the other end side.
