PRESSURE CONTAINER, AND BUOYANT BODY AND EXPLORING DEVICE WHICH ARE PROVIDED WITH THE SAME

摘要

Provided are a pressure container having enhanced reliability for pressure-resistant performance and sealing performance of connecting portions between outer shells, and a buoyant body and an exploring device which are provided with the pressure container. The pressure container has a hemispherical first outer shell (2) consisting of ceramics, a hemispherical second outer shell (3) consisting of ceramics, and a right hollow circular cylindrical third outer shell (4) consisting of ceramics. The pressure container also has circular ring-shaped first and second connecting bodies (5, 6) mounted between the first and the third outer shells (2, 4) and between the second and third outer shell (3, 4) and consisting of a material having a modulus of elasticity smaller than those of the first to third outer shells (2 to 4).
