A thrust generating apparatus is configured to generate thrust by ejecting water. The thrust generating apparatus includes: a first water lubricated bearing opposed to one side surface and outer peripheral surface of rotor main body and supports a thrust and radial load; a second water lubricated bearing opposed to the other side surface and outer peripheral surface of rotor main body and supports the thrust and radial load; a first water intake port that opens toward a portion of a channel; a second water intake port that opens toward another portion of the channel; a first water conveyance tube through which the water having flowed through the first water intake port is guided to the second water lubricated bearing; and a second water conveyance tube through which the water having flowed through the second water intake port is guided to the first water lubricated bearing.

Thrust generating apparatus

A thrust generating apparatus is provided under water and configured to generate thrust by ejecting the water. A rotor main body includes: a first member including a side surface and outer peripheral surface which are opposed to a first water lubricated bearing; a second member including a side surface and outer peripheral surface which are opposed to a second water lubricated bearing; and a third member including a supporting surface contacting an inner peripheral surface of a rotor core. The first to third members are fixed to one another so that each member is detachable.
