能にする微小間隙が生じる。 When installing the shield plate 3, first stack the end of the shield plate 3 on the bracket 11 and place it in the recess 21.
is engaged with the outer peripheral surface of the annular projecting wall 16. Next, the end cover 4 is placed on the end of the shield plate 3, and the connecting pins 26 are inserted into the connecting holes 22, and the click teeth 18, 18, 27, 27, and so on are engaged with each other. Subsequently, the collar 13 is fitted into the inner surface of the boss 24 and the recess 28 of the end cover 4, and the protrusion 31 is engaged with the recess 20 of the bracket 11. Finally, the screw 14 is inserted into the center hole 15 of the collar 13 and the bracket 11, and the nut 9 is screwed on. In this case, as shown in FIG. 2, the inner end of the collar 13 abuts against the outer surface of the bracket 11, so that the shield plate 3 and the end cover are placed between the large diameter portion 30 of the collar 13 and the bracket 11. A minute gap is created that allows rotation of 4.

く、ビス１４に緩みを生じさせない。 Therefore, if you take the knob 5 to open and close the window hole 2 and rotate the shield plate 3 up and down, the connecting pin 2
The end cover 4 connected to the shield plate 3 via 6 rotates around the collar 13.
Then, when the end cover 4 rotates, the click teeth 18, 18...; 27, 27... deform the elastic piece 17 and change the engagement position, so that the shield plate 3
can be held at a desired rotational position. During this time, the collar 13 does not rotate because the protrusion 31 is engaged with the groove 20 of the bracket 11, and the screw 14 is not loosened.
