PROBLEM TO BE SOLVED: To provide a structure of a submersible vehicle having miniaturization, high mobility and a wide visual field, and capable of also simultaneously securing a proper degree of freedom of the body of a crewman, without complicating the whole structure.SOLUTION: A pressure-proof shell 1 is provided as a boarding space constituted of a material whose three-dimentional shape is a spindle shape or a shell shape or a cylindrical shape or a shape which is similar to this and whose whole is transparent. A size of the pressure-proof shell is set on the basis of having a height and an inner diameter of not contacting with a pressure-proof shell inner wall even if an arm is extended upward or forward in a state where a human being of average stature vertically stands to the radial direction in the inside of the pressure-proof shell.SELECTED DRAWING: Figure 2 |
