Disclosed is a wind power generating apparatus (1A) including a rotor head (6) that rotates when wind turbine blades (9) receives outside wind and that drivers a generator (11) provided inside a nacelle (5) to generate electricity. A nacelle internal air passage (18) through which outside air flows is provided inside the nacelle (5). The nacelle infernal air passage (18) is isolated from an internal space (S1) of nacelle (5). A heat generating devices (such as the generator (11)) provided in the internal space (S1) is provided adjacent to the nacelle internal air passage (18). Specifically disclosed is that at least a portion of a wall body (17) has a double-walled structure including an outer wall (17a) and an inner wall (17b). The space between the outer wall (17a) and the inner 17 wall (17b) is employed as the nacelle interior air passage (18); a heat generating device is provided adjacent to the inner wall (17b). |
