ツキが起因して効果不安定となる恐れがある。[Prior Art] Conventionally, an adjusting plate for controlling the amount of blown air is provided inside a register case that forms an air outlet for ventilating a passenger compartment of a vehicle such as an automobile. That is, as shown in FIGS. 5 and 6, the adjusting plate 3 is provided in the vicinity of the edge 11 of the register case 10, and the edge 11 is fitted and connected to the inner circumference of the duct 2 communicating with the air conditioner. As a result, the step portion 5 having the sharp edge portion 14 is formed on the edge 11 of the register case 10. The airflow flowing in the outlet of the connecting portion 4 between the register case 10 and the duct 2 passes through the minute gap S generated between the adjusting plate 3 and the register case 10 at the position just before the closing of the adjusting plate 3. When doing, Karman vortex was generated, and there was a case where whistling sound (vortex sound) called "pee" was generated. Therefore, in order to suppress the whistling sound, there is a case where a rough surface material 6 such as felt or urethane is attached to the edge portion 14 as shown in FIG. 4, but in this case, the rough surface material 6 is used. However, there is a problem that the cost of the register device for the attachment is increased. Furthermore, there is a risk that the effects will become unstable due to variations during attachment of the rough surface material 6.

Is a duct, 3 is an adjusting plate provided near the edge 11 in the register case 1 for controlling the blown air volume, 12 is a ridge for bringing the adjusting plate 3 into contact to bring it into a fully closed state, and 13 is the register case 1 Simultaneously with molding, a plurality of notches are provided at a predetermined interval on the inner peripheral portion of the end edge 11 to form an uneven discontinuous surface on the inner peripheral portion of the end edge 11. The edge 11 of the register case 1 is fitted and connected to the inner circumference of the duct 2, and the edge 11 forms a step portion 5.

３の全閉直前の位置における笛吹き音を抑制し消音効果
を発揮する。In the above configuration, when the adjustment plate 3 expands and contracts the gap S with the ridge 12 to control the blowout air volume, the airflow flowing toward the stepped portion 5 of the register case 1 that is the blowout port has the adjustment plate 3 Before passing through the minute gap S generated between the ridge 12 and the ridge 12 of the register case 1, a plurality of notches are provided at a predetermined interval on the inner peripheral portion of the end edge 11, and It is possible to prevent the whistling sound by disturbing the flow by the uneven discontinuous surface 13 formed in the peripheral portion and suppressing the generation of Karman vortices when passing through the gap S. An example of this effect is shown in FIG. In the figure, a line X indicates an embodiment of the present invention, and a line Y indicates a step portion 5 having a sharp edge portion 14.
11 shows a conventional example in which the inner circumference of the edge 11 is formed by a flat continuous surface. In the figure, the vertical axis represents the sound pressure, and the horizontal axis represents the opening degree between the adjusting plate 3 and the protrusion 12. The register case 1 of this invention suppresses the whistle blowing sound at the position immediately before the adjustment plate 3 is fully closed, and exerts a sound deadening effect.
