A louver decreasing the total number of required louvers, reducing the manufacturing cost, and obtaining the excellent external appearance. A louver 20 of a device for shifting the wind direction 11 provided at a blast port 83 of a air-conditioner 10 having a first wind rectification surface 21 which is in a plane form, parallel to the blast direction, and a second wind rectification surface 22 which is in the plane form, positioned in a parallel state to the first wind rectification surface 21, and connected in a stair form by a difference of elevation surface 23, and is positioned so that the difference of elevation surface 23 faces the blast source at a slant. |
