One end of a flexible shaft, is connected to an output shaft of the engine and the other end of which is connected to a rotary shaft of the fan. The flexible shaft has a flexible outer tube for connecting a casing of the engine with a housing of the fan, and a rotary shaft formed of a helical coil rounded helically around the axial line of the outer tube and extending axially in the outer tube, one end of the rotary shaft being connected to the output shaft of the engine and the other end of the rotary shaft of the flexible shaft being connected to the rotary shaft of the fan. The rotary shaft of the flexible shaft is connected to the rotary shaft of the fan through a power transmitting direction varying device. |
