PROBLEM TO BE SOLVED: To provide an exhaust air agitation device capable of simplifying a structure and having high agitation effect.SOLUTION: An exhaust air agitation device 1 mounted in a cylindrical body 101 forming an exhaust air flow passage comprises: a main body 3 including plural substrates 22,24, 26,28,30 opposed to each other at predetermined intervals; and plural blade parts 5-20 provided on a downstream side in a flow direction D of the exhaust air among the substrates 22,24,26,28,30, and inclined in the flow direction D of the exhaust air. The plural blade parts 5-20 are formed so that a path exists in which a vector X of the respective blade parts defined below passes around in a constant direction when seen from a downstream side in the exhaust air flow direction D. The vector X is a component in a plane orthogonal to the exhaust air flow direction D among vectors in a direction for inducing exhaust air by the blade parts 5-20. |
