1. A combined power system comprising:
a rotary electric machine system including a rotary electric machine, and a rotary electric machine housing in which a rotating shaft of the rotary electric machine is rotatably supported; and
an internal combustion engine including an output shaft configured to rotate integrally with the rotating shaft,
the combined power system further comprising:
a first bearing and a second bearing each configured to rotatably support the rotating shaft in the rotary electric machine housing; and
a terminal casing disposed on an outer side wall of the rotary electric machine housing and in which electric terminal portions are accommodated, the electric terminal portions configured to transmit and receive electrical power between the rotary electric machine and an external device,
wherein, in the terminal casing and the rotary electric machine housing, a flow passage through which a gas supplied from a gas supply source flows is formed with the terminal casing on an upstream side thereof and the rotary electric machine housing on a downstream side thereof,
the first bearing and the second bearing are disposed in the flow passage inside the rotary electric machine housing,
the rotary electric machine housing includes a main housing that surrounds the rotary electric machine,
a hollow pipe member is arranged adjacent to an outer circumferential portion of the main housing and distributes the gas that is a compressed air coming from the internal combustion engine,
the main housing includes a cooling jacket through which a cooling medium flows,
the cooling jacket cools the rotary electric machine and the gas flowing through the hollow pipe member, and
the terminal casing receives the gas that has passed through the hollow pipe member.
