A blow out grill comprising: an outdoors-side opening communicated with a duct; an indoors-side opening communicated with the inside of a room; a panel base portion forming a wind blowing path of carried air between the indoors-side opening and the outdoors-side opening; a panel portion formed in a polygonal shape, and disposed opposite to the panel base portion; a blow out port communicated with the wind blowing path and formed between the panel portion and the panel base portion, the blow out port having a substantially L-shaped opening; a first air-flow-guiding projected portion formed at the panel base portion and directed to a side of the panel portion; a second air-flow-guiding projected portion formed at the panel portion and directed to a side of the panel base portion; and a third air-flow-guiding projected portion, disposed at a corner portion of the polygonal shape of the panel portion, the corner portion being a portion from which air is discharged from the blow out grill, a plane of the third air-flow-guiding projected portion being parallel to a plane of the first air-flow-guiding projected portion, the third air-flow-guiding projected portion being formed so as to project closer to the panel base portion than the second air-flow-guiding projected portion, and having a substantially L-shaped cross-section parallel to a plane of the panel portion.
