<p>PROBLEM TO BE SOLVED: To normally transmit driving force without causing damage even in a case where an exhaust heat recovery heat generation device is applied in a magnetic coupling that transmits rotation of a power turbine to a speed reducer, the exhaust heat recovery heat generation device composing an exhaust recovery type ship propulsion device installed for, for example, recovering exhaust from a diesel engine (internal combustion engine) as main machine for propelling a ship.SOLUTION: On a peripheral wall 72 composing an inner rotor 61, a plurality of slits 78 are provided along a circumferential direction, the slit 78 being located between an N-pole magnet 74 and a S-pole magnet 75, allowing communication between the outer peripheral face and inner peripheral face of the peripheral wall 72 and extending from the end face of the peripheral wall 72 to the inside face of a bottom plate 71 composing the inner rotor 61.</p> |
