ンパクトにできないと言う欠点があつた。[Detailed description of the invention] As shown in Fig. 1, a conventional air volume adjustment damper has a damper body 2' with a built-in rectifier plate 1' attached to the air diff user, and an adjustment plate hinged with an adjustment screw 3'. Although the air volume is adjusted by opening and closing the adjusting plate 4', there is a drawback in that the damper as a whole cannot be made thin and compact because of the need to secure space for opening and closing the adjusting plate 4'.

ト高となる問題がある。 In order to solve this problem, a proposal has been made as seen in Utility Model Publication No. 56-55559, but this method requires relatively precise machining for the grooves to be drilled in the blades and the protrusions that fit into the grooves. There is a problem in that precision is required and costs are high.

である。 When superimposing the above child blades 5', 5''...
The convex body 7a and the concave body 7b of each child blade are arranged so that they are not overlapped in the same direction, that is, the child blade 5' is
On the other hand, the respective convex bodies 7a and concave bodies 7b are superimposed in opposite positions. That is,
This is done by turning over the child blades alternately, which means that in the handling operation described below, the convex body 7a of one blade is replaced by the convex body 7'a formed on the back surface of the other blade. In contrast, the opening and closing operations of the concave body 7b are automatically performed in such a manner that the convex body 7'a formed on the back surface of the concave body 7b sequentially engages with the convex bodies 7a of other blades. Thus, when the last master blade 1 is stacked, the convex body 3a is engaged with the convex body 7'a of the lower side child blade 5 in the same relationship. FIG. 6 is a diagram showing the completed assembly, in which A shows the damper main body 8 in an open state, and B shows a closed state. In this embodiment, it is composed of four child blades (however, one blade is fixed to the damper body and the remaining three are movable) and one main blade. The damper body 8 is opened and closed by engaging a driver with it and rotating it from outside the damper body 8. In the illustrated example, it is closed by clockwise rotation of the bolt 10,
It is opened by turning the bolt 10 to the left, and to explain the operation of closing it in the currently opened state, the main blade 1 turns by turning the bolt 10 to the right, and in the turning process, the back surface of the concave body 3b The convex body 3a of the part engages with the convex body 7'a of the child blade on the lower side to rotate it,
In addition, the convex body 7a on the back surface of the concave body 7'b of the child blade engages with the convex body 7a of another child blade during its rotation process, causing it to rotate. The left and right wing plates that had been closed are pulled out one after another, and the opening is closed, and at the end of the closure, the stopper piece 4 provided on the surface side of the main blade 1
The damper stops when it comes into contact with one side edge of the child blade 5 fixed to the circular frame 8a of the damper body. Next, to open the bolt 10, turn it counterclockwise, and at this time, the stopper piece 4 of the main blade 1
In the course of its rotation, it sequentially contacts one side edge of the overlapping child blades 5', 5'', and 5, and pulls them in the same direction to return to the original open state.

本考案に於いて各羽根に形成する凸体と凹体は
プレス作業で簡単に得られるのであつて、工作は
極めて容易である。また、厳しい精度を必要とし

操作容易で且つ安価なものである。 In the present invention, the convex bodies and concave bodies formed on each blade can be easily obtained by pressing, and the machining is extremely easy. Moreover, strict precision is not required. Moreover, the whole can be constructed thinly,
It is easy to operate and inexpensive.
