PROBLEM TO BE SOLVED: To stabilize turning movement, and to suppress noise during turning by constantly maintaining a gap between separated changing plates at a substantially constant even when the wind direction changing plates is deformed due to thermal expansion or contraction, and improving sliding performance of the wind direction changing plate. SOLUTION: In the so-called separated type louver 2 wherein a left louver 2a and a right louver 2b (two or more wind direction changing plates) are serially connected in a horizontal direction, the left louver 2a and the right louver 2b are connected while maintaining the gap between the wind direction changing plates 2a and 2b at a substantially constant by a connecting member 30 engaging with a connection shaft 23 of adjacent end parts of the left louver 2a and the right louver 2b, and turnably connecting the left louver 2a and the right louver 2b.
