At the same time, it is swingably coupled to the mounting member 901 of the vertical frame 9A.

Next, attachment of the opening / closing arm 13 will be described. First, the case of attaching the opening / closing arm 13A to one end 11A of the blade 11 will be described with reference to FIG. 8. The horizontal plate portion 1501 is engaged with the guide groove 1113 to attach the holder 15 to the blade 11. , It is slid to an inner part apart from the end 11A of the blade 11. Then, the base piece 1301 of the opening / closing arm 13A is placed on the back surface B of the blade 11 at a position between the ridge 1115 and the guide groove 1113, and the projection 1313 is positioned in the notch 1117. Next, the holder 15 is slid to the end 1A of the blade 11. By this slide, when the bent portion 1511B of the spring plate portion 1511 is positioned on the base piece portion 1301 of the opening / closing arm 13A, the bending portion 1511B is once lifted above the base piece portion 1301 of the opening / closing arm 13A. When the holder 15 is slid until the portion 1511B is located in the notch 1311 of the opening / closing arm 13A, the bent portion 1511B swings through the notch 1311 to the back surface B side of the blade 11, and the blade 11 Engages with the back surface B of the. Next, the holder 15 and the opening / closing arm 13A are connected through the holes 1305, 1505 and the pin 19, and the attachment of the opening / closing arm 13A at one end 11A of the blade 11 is completed.

With this mounting completed, the bent portion 1511B is engaged with the back surface B of the blade plate 11, and the elasticity of the spring plate portion 1511 urges the holder 15 away from the back surface B of the blade plate 11. Since both sides of the horizontal plate portion 1501 are pressed against the upper wall 1113C of the guide groove 1113, even if there is a dimensional error in the height of the guide groove 1113, the holder 15 is guided without rattling. Since it can be attached to the groove 1113, rattling of the opening / closing arm 13A attached to the holder 15 can be prevented. When it is desired to move the holder 15 and the opening / closing arm 13 along the longitudinal direction of the blade 11 within the range in which the protrusion 1313 can move in the notch 1117, the upper surface 1511D is lifted and the bent portion 1511B. Is separated from the back surface B of the blade plate 11, and the holder 15 is slid in this state. At the one end 11A of the blade plate 11, since the protruding piece portion 1313 is located in the notch 1117, the holder 15 and the opening / closing arm 13A cannot be removed from the blade plate 11.

Next, a case where the opening / closing arm 13B is attached to the other end 11B of the blade 11 will be described with reference to FIG. 9. As described above, the lateral plate 1501 is engaged with the guide groove 1113. The holder 15 is attached to the vane plate 11 by sliding the holder 15 to an inner portion apart from the end portion 11B of the vane plate 11. Next, the base piece 1301 of the opening / closing arm 13B is placed on the back surface B of the blade 11 at a position between the ridge 1115 and the guide groove 1113, and the holder 15 is slid on the end 1B of the blade 11. Let By this slide, when the bent portion 1511B of the spring plate portion 1511 is positioned on the base piece portion 1301 of the opening / closing arm 13A, the bending portion 1511B is once lifted above the base piece portion 1301 of the opening / closing arm 13A as described above. However, when the holder 15 is slid until the bent portion 1511B is located in the notch 1311 of the opening / closing arm 13A, the bent portion 1511B swings toward the back surface B side of the blade 11 through the notch 1311. , Engages with the back surface B of the blade 11. Since the other end 11B of the blade 11 does not have the notch 1117 and the protruding piece 1313, the holder 15 is attached to the end of the blade 11 with the lateral plate 1501 engaged with the guide groove 1113. The base piece portion 1301 of the opening / closing arm 13 may be inserted between the horizontal plate portion 1501 of the holder 15 and the back surface B of the blade plate 11 while being positioned at 11B. Next, the holder 15 and the opening / closing arm 13B are connected to each other through the holes 1305, 1505 and the pin 19, and the attachment of the opening / closing arm 13B at one end 11B of the blade 11 is completed.

Since the bent portion 1511B is engaged with the back surface B of the vane plate 11 in the state where this attachment is completed, both sides of the horizontal plate portion 1501 are pressed against the upper wall 1113C of the guide groove 1113, as described above. Therefore, even if there is a dimensional error in the height of the guide groove 1113, the holder 15 can be attached to the guide groove 1113 without rattling, and the opening / closing arm 13A attached to the holder 15 rattles. It can prevent sticking. When it is desired to move the holder 15 and the opening / closing arm 13B along the longitudinal direction of the blade plate 11, the upper surface portion 1511D is lifted and the bent portion 1511B is separated from the back surface B of the blade plate 11 as described above. .. Further, since the other end 11B does not have the notch 1117 and the projecting piece 1313, the holder 15 and the opening / closing arm 13B slide to the outside of the blade 11 even if the frame 9 is thermally expanded and deformed due to temperature rise. By doing so, this thermal expansion deformation is absorbed, and the opening / closing operation of the blade 11 is performed without any hindrance.
