To provide a warm air circulator, in which the number of louvers is reduced to improve design performance, and in which safety and cleaning easiness are improved.

A combustion chamber 2 provided with a burner 4 is disposed in the main body 1, and heat generated by the burner 4 is emitted into the room through a warm air blow port 8 provided in a front surface of the main body 1 by a warm air blower 7. The louvers 9a, 9b, and 9c are provided in three stages on the warm air blow port 8. Overhanging size of the uppermost louver 9a toward the combustion chamber 2 is set to be shorter than that of the other louvers 9b and 9c.
