<p>PROBLEM TO BE SOLVED: To solve the problem in which, in the case where a cross-sectional shape of a connection bar is configured at an angle vertical to a rotation center of a left/right blade, when this angle is different from a main flow of a blowing air blown out of an air outlet, the connection bar becomes draft resistance and deteriorates air blowing performance.SOLUTION: A connection bar 5 includes: a flat plate-like holding part 15 for holding a connection protrusion 12 provided at a left/right blade 4; and a flat rod-like connection part 16 for connecting the holding parts 15 with each other. The holding part 15 is provided in a manner vertical with respect to a rotation center axis of the left/right blade 4. The connection part 16 is provided in an inclined manner with respect to the holding part 15. Thereby, the connection bar 5 can reduce the possibility of the connection bar 5 becoming draft resistance to blowing air while rotating the left/right blade smoothly, so that air blowing performance can be enhanced and energy saving can be achieved.</p> |
