<P>PROBLEM TO BE SOLVED: To provide an easily handleable pressure indicator for a gas spring and to provide a compact and inexpensive pressure indicator for a gas spring. Ž<P>SOLUTION: This pressure indicator 10 for the gas spring for indicating pressure of the gas stored in a compressed gas filled chamber 3 in the gas spring 1 includes a valve case 11 fixed on the gas spring, a gas filling valve 14 incorporated in the valve case to fill it with compressed gas, a case member 25 fixed on the valve case, a movable pressure receiving member 35 mounted movably in the case member, a gas pressure indicating part 42 formed in a tip part of the movable pressure receiving member to protrude the outside of the case member, a pressure receiving part 38 formed at least at one end of the movable pressure receiving member, a gas pressure application means 45 for applying gas pressure of the compressed gas to the pressure receiving part, and a compression spring 48 for letting elastic force opposing to pressing force of the gas pressure act on the movable pressure receiving member.
