Claims

[Claims for Utility Model Registration] 1. A guide vane device installed at the elbow of a duct forming an air flow path to rectify the air flow, which has an adjustment plate made of a single thin plate. , a predetermined pattern of slits is formed in the adjustment plate, and the adjustment plate is integrally provided with vanes delineated by the slits, the vanes extending in the same direction as the bend of the elbow. A guide vane device equipped with a curved surface. 2. The vane is defined by two slits, the ends of one of which are located close to the ends of the other slit, thereby forming two slits on the periphery of the vane. A guide vane device according to claim 1, wherein a slit discontinuous portion is formed so that the angle of the vane can be adjusted using the discontinuous portion as a support axis. 3. Claim No. 3, characterized in that the slit discontinuity is located approximately at the center of a slit defining two opposing sides of the blade defined by the slit. The guide vane device according to item 1 or 2. 4. The terminal ends of each of the slits are formed with extended portions extending in directions facing each other and in directions away from each other, and the discontinuous portion has an elongated connecting portion extending in a direction substantially orthogonal to the slit portion defining the side. Scope of Utility Model Registration Claims Paragraph 1, Paragraph 2, or Paragraph 3
Guide vane device as described in section. 5 A first side pair defining two opposing sides of the blade on which the two discontinuous parts are formed, and two other opposite sides of the blade connected to this first side pair. and a second pair of sides defining sides of the second side.
5. The guide vane device according to claim 4, wherein adjacent blade side edges of the side pair are defined by a single slit. 6. The guide vane device according to claim 1, wherein one vane is provided whose outline is defined by the slit. 7. The guide vane device according to claim 1, wherein a plurality of vanes whose contours are defined by the slits are provided. 8. The guide vane device according to claim 7, wherein the blade widths of the blades are all different in length. 9 The blade widths of the blades are all different in length, and the blade having the longest pair of first side sides is the blade having the shortest pair of side sides at the outermost side of the bending point of the elbow portion. 8. The guide vane device according to claim 7, wherein the guide vanes are arranged sequentially so as to be located at the innermost side.
