PROBLEM TO BE SOLVED: To provide a submarine device and a turn prevention mechanism of an internal unit thereof, which reduces the possibility of damaging internal unit when torque is applied to the unit. SOLUTION: In the submarine device in which the cylindrical internal unit is assembled into a cylindrical pressure-resistant enclosure via a shock-absorbing spring, a shock-absorbing mechanism having a ring receiving seat which is in contact with the end surface of the internal unit, a ring pedestal opposing the receiving seat in the axial direction, a ring disc spring arranged between the receiving seat and the pedestal, and a stop ring for blocking the movement of the pedestal in the axial direction against the pressure-resistant enclosure, is provided at the opposite ends of the internal unit. The pedestal is fixed to the pressure-resistant enclosure, at least one shock-absorbing mechanism has a means for limiting the turn of the internal unit against the pedestal, without regulating the turn of the receiving seat against the pedestal and the internal unit.
