ABSTRACT:
An elastic body apparatus includes a pneumatic pressure sealing member formed of a hollow flexible material and sealing therein a high pressure pneumatic gas, a movable member driven by an external force against the pressure of the pneumatic pressure sealing member, a fixed shell enveloping a fixed portion of the pneumatic pressure sealing member, and an elastic shell having plate spring portions for applying a spring force in the same direction as the pressing direction of the pneumatic pressure sealing member to the movable member, and disposed at a position enveloping a displacing portion of the pneumatic pressure sealing member. The elastic shell serves as a shell and a spring body, and even if the pressure of the pneumatic pressure sealing member is increased, the pneumatic pressure sealing member is prevented from being deformed in excess of a normal level, and the pressure is transmitted to the movable member through the pneumatic pressure sealing member.
