To provide an air outlet device of a spot type air conditioner, which is capable of achieving a sufficient air conditioning effect, while maintaining reachability of an air-conditioned air, even when a distance from an opening of a duct to an object to be air-conditioned is increased.
The air outlet device includes: a cylindrical connection 21 that is equally set as a flow channel area of a ventilation duct 12b, and connected with the ventilation duct 12b; an expanded pipe 22 where the flow channel area is sequentially increased more than the flow channel area of the connection 21 toward the downstream side of the air-conditioned air; a diffusion part 23, which is arranged at an opening 22a opened at a tip side of the expanded pipe 22 and formed of a porous body of a three-dimensional frame mesh, for diffusing a flow of the air-conditioned air from a center side of the opening 22a to a surrounding side; and a rectification part 24, which is adjacently arranged at the downstream side of the air-conditioned air more than the diffusion part 23 of the opening 22a, for rectifying a flow of the diffused air-conditioned air in an axial direction of the opening 22a.
