  In the above figure, reference numeral 1 is a louver, and this louver 1 is mainly composed of a plurality of receiving members 3 and a plurality of louver members 4 fixed directly to a wall case 2 of a building.

  As shown in FIG. 3, the long receiving member 3 is an extruded shape of aluminum or an alloy thereof, and is formed from a fixed piece 5 and locking pieces 6 on both sides thereof in a U-shaped cross section. The fixing piece 5 is for fixing to the wall housing 2, but the locking piece 6 is for attaching the louver material 4, and protrudes perpendicularly to the wall housing 2. The locking piece 6 projects slightly from the inside of the end of the fixed piece 5, and a locking receiving jaw 7 is formed at the tip of the locking piece 6. The locking receiving jaw 7 is formed outward and has a pointed tip.

  The louver material 4 is made of an extruded shape of aluminum or an alloy thereof, and the louver material 4 has a groove 10 formed on one side of the hollow portion 8. The concave groove portion 10 is formed in a size that can be fitted to the outside of the both side locking pieces 6 of the receiving member 3, and a locking jaw 11 is formed inside the tip of both sides of the concave groove portion 10. The locking jaw 11 is formed inward, and the tip side is formed to be sharp, but the tip is formed flat. Further, ribs 12 are formed on the inner sides of both side surfaces of the louver material 4 so as to face each other. The length of the rib 12 is set to be at least equal to or larger than the width dimension of the locking receiving jaw 7 of the receiving member 3. Furthermore, it is preferable that the rib 12 is formed at a position where the tip of the locking receiving jaw 7 of the receiving member 3 locked to the locking jaw 11 of the louver material 4 comes into contact. Further, the dimension from the rib 12 to the tip of the locking jaw 11 is shorter than the dimension from the lower surface of the fixed piece 5 of the receiving member 3 to the tip of the locking piece 6. A protrusion 14 having a C-shaped cross section is formed along the longitudinal direction inside the partition wall 13 constituting the hollow portion 8.

  In the above configuration, when the louver material 4 is attached to the wall housing 2, first, the receiving member 3 is fixed to the wall housing 2 as shown in FIGS. 4 (a) and 4 (b). In this case, as shown in FIGS. 1 and 2, the plurality of receiving members 3 are fixed, and the fixing pieces 5 of the receiving members 3 are screwed to the wall housing 2 and directly attached. The receiving members 3 are attached so as to be parallel to each other. Next, as shown in FIGS. 2B and 2C, the louver material 4 is pressed toward the receiving member 3, and the concave groove portion 10 of the louver material 4 is fitted from the outside of the receiving member 3 as shown in FIG. Then, the locking jaw 11 of the louver material 4 is elastically locked to the locking receiving jaw 7 inside the concave groove portion 10.
