Abstract
A turbine-type underwater hydraulic motor includes a hermetically sealed chamber filled with oil, and bearings of rotating parts and a reduction gear unit are sealed in said sealed chamber. A part of the partitions isolating the sealed chamber from the exterior is comprised of a resilient member and thus the water pressure outside the motor and the oil pressures within the sealed chamber are balanced, thereby preventing the leakage of the oil and the entry of the water.
