As in the conventional case, the opening area in the duct 10 is adjusted by bending each of the adjusting blades 3 to determine the amount of conditioned air passing, that is, the amount of conditioned air. When increasing the air volume, the adjustment blade 3 is bent in a predetermined direction to increase the opening area inside the duct 10. In a state in which all of the adjustment blades 3 are bent (see FIGS. 2 and 3),
The opening area in the duct 10 is maximized, and the conditioned air passes through the duct 10 to the downstream side with little resistance. On the other hand, when suppressing the air volume, the adjustment blade 3 is returned in the opposite direction to the above case, the opening area in the duct 10 is reduced, and the passage amount of the conditioned air is reduced.

なく安全に調整羽根３を操作できる。As described above, in the air volume adjusting plate according to the present embodiment, the adjusting blade 3 is bent in the same manner as the conventional one to adjust the opening area in the duct 10 to adjust the air volume. Since the sheet 4 made of a sound-absorbing material that covers the entire substantially plate-like body is disposed, the airflow of the conditioned air is easily generated when passing between the adjustment blades 3 or between the adjustment blades 3 and the duct 10. While noise such as wind noise can be suppressed, other noises can be absorbed by the sheet 4 on the surface of the adjusting blade 3, so that the noise can be significantly reduced as a whole. In addition, since the substantially plate-like body as a whole is covered with the sheet 4 and it is not necessary to directly touch the substantially plate-like body when operating the adjustment blade 3, the adjustment blade 3 can be safely operated without fear of injury.

する。As described above, according to the present invention, the adjusting blade is formed to be bent at a predetermined angle, and the sound absorbing material layer is disposed on the outer surface of the substantially plate-like body including the adjusting blade. Because the body is not exposed to the outside, even if the airflow hits the edge of the adjusting blade, wind noise and the like are less likely to be generated, and the noise caused by the air volume adjusting plate can be reduced, and the noise transmitted from the upstream side can be reduced by the air volume adjusting plate. Sound is absorbed by the surface to prevent propagation to the downstream side, and the effect of reducing the adverse effect of noise can be achieved. In addition, there is an effect that it is not necessary to directly touch the substantially plate-shaped body when operating the adjusting blade, and the operation can be performed safely.

This has the effect that noise such as wind noise which is likely to be generated when the air flow passes through the gap outside the outer periphery of the substantially plate-shaped body can be suppressed. Further, according to the present invention, the outer surface of the entire substantially plate-like body including the adjusting blade is planted with hair, and the substantially plate-like body is not exposed to the outside, so that a wind noise which is likely to be generated when an airflow hits the adjusting blade is provided. And the like, and the noise propagating from the upstream side is absorbed by the adjusting blade portion to prevent the noise from propagating to the downstream side, so that an adverse effect due to the noise can be reduced.

果を有する。According to the present invention, a sheet made of a sound-absorbing material is attached to both sides of a substantially plate-like body having a slit formed therein.
By cutting the bonded sheet at the intermediate position in the width direction of each slit and allowing each adjustment blade to bend, each process of punching the slit into a substantially plate-like body, bonding the sheet, and cutting the sheet is continuous. In addition to being easy to automate and saving labor, it is possible to obtain a structure in which the entire outer surface of the substantially plate-like body is covered with a sheet by a simple process so that noise is hardly generated, and the cost can be reduced. In addition, the sheet can be cut efficiently, and there is an effect that unnecessary cutting chips of the sheet are hardly generated, and waste of the sheet can be suppressed.
