<p>A screw loosening prevention structure 10 and a gas-pressure device 11 are provided. The structure includes a first member 12 that is formed with a container space 14 filled with gas, and includes a first threaded portion 17, a second member 13 that includes a second threaded portion 21, wherein the second member 13 is threadedly coupled with the first member 12 by threadedly engaging the second threaded portion 21 with the first threaded portion 17, and receives a pressure from the gas in the container space 14 of the first member 12, and a spring member 30 provided between the first and second members 12, 13 in a deformed state in which the displacement of the spring member 30 is greater than a relative displacement of the first and second members 12, 13 due to a loosening factor including the gas pressure that is received by this second member 13.
