PRESSURE RESISTANT CONTAINER AND PROBE PROVIDED WITH SAME

摘要

There are provide a pressure-resistant container which is less likely to be damaged due to stress concentration even in deep seas of 1000 m or deeper below sea level, and an exploration machine provided with the same. A pressure-resistant container (1) includes a cylindrical first outer shell member (2); and substantially hemispherical second outer shell members (3) which are respectively connected to both ends (2a, 2b) of the first outer shell member (2), and is constructed by selecting materials so that a Young's modulus E2 of a base material which constitutes the second outer shell members (3) is smaller than a Young's modulus E1 of a base material which constitutes the first outer shell member (2) .
