<p>Embodiments of the present invention may include an intake air supply structure for a turbo supercharger (1) which includes a exhaust side impeller (22), a intake side impeller (21) of a compressor, an intake flow path (11), and an intake air swirling means (50; 50A; 50B; 50C). The exhaust side impeller (22) is rotated by exhaust gas discharged from an internal combustion engine. The intake side impeller (21) is connected to the exhaust side impeller (22), and rotates to force-feed intake air into the internal combustion engine. The intake flow path (11) guides the intake air to the intake side impeller (21). The intake air swirling means (50; 50A; 50B; 50C) is provided on an outer periphery of the intake flow path (11). The intake air swirling means (50; 50A; 50B; 50C) is configured to extract a portion of the intake air inside the intake flow path (11) temporarily to an exterior of the intake flow path (11), and to swirl the extracted intake air in the same direction as a rotational direction of the intake side impeller (21) along an outer periphery of the intake flow path (11), and to discharge the swirled intake air into the intake flow path (11).
