PROBLEM TO BE SOLVED: To easily remove a housing from a body part.SOLUTION: A power generation device 10 includes: a rotary body 13; a housing 12; a support post 11; and a generator 100 including a stator 17 for power generation and a rotor 14 for power generation, and feeds generated power to the outside via a power cable 102 connected to the stator 17 for power generation. The power generation device 10 also includes a power generation section 101 in addition to the generator 100. The power generation section 101 includes a rotor 15 for excitation, and a stator 18 for excitation which generates a rotary magnetic field for the rotor 15 for excitation on the basis of power supply from a power transmission station 103. In the housing 12, the rotor 14 for power generation and the rotor 15 for excitation are disposed side by side in an axial direction of the rotary body 13 and incorporated so as to be rotatable integrally with the rotary body 13. In the support post 11, the stator 17 for power generation and the stator 18 for excitation are disposed side by side oppositely to the corresponding rotors respectively. |
