  The knob member 33 is movable in the front-rear direction within the inner casing 32. The outer casing 31 is also movable in the front-rear direction integrally with the knob member 33.

  As shown in FIGS. 4 to 6, a compression coil spring 34 is interposed between the knob member 33 and the inner casing 32 in a compressed state. The compression coil spring 34 is extrapolated to the shaft portion 33f, and the rear side portion is accommodated in an annular space 30a between the cylindrical portion 32g and the shaft portion 33f. The front end portion of the compression coil spring 34 is abutted against the front plate 33 a of the knob member 33, and the rear end portion of the compression coil spring 34 is abutted against the step 32 h of the inner casing 32.

  By the spring force of the compression coil spring 34, the knob member 33 is urged forward, and the inner casing 32 is urged rearward. When the knob member 33 is urged forward, the outer casing 31 coupled integrally with the knob member 33 is also urged forward.

  As a result, as shown in FIG. 4, the upper and lower flanges 32 b of the inner casing 32 are elastically pressed against the upper and lower sides of the upper and lower edges of the operation window 14 b of the front wall 14, and left and right of the flange 31 b of the outer casing 31. The central portion is elastically pressed against the back surfaces of the upper and lower edges of the operation window 14 b of the front wall 14. Therefore, the inner casing 32 and the outer casing 31 sandwich the upper and lower edges of the operation window 14b of the front wall 14 from the front and rear. Therefore, the operation knob 30 is engaged only with the front wall 14 of the front wall 14 and the rear wall 15 of the ventilation main body 11. The rear side surface (the right side in FIG. 5) of the outer casing 31 is separated from the rear wall 15, and a gap is formed between the outer casing 31 and the rear wall 15.

  As shown in FIG. 5, when the operation knob 30 is in the open position, one wall 32c of the inner casing 32 abuts against one edge of the operation window 14b. Further, by the urging of the compression coil spring 34, the protruding portion 35a of the wing portion 35 on the same side is elastically pressed against the back surface of the front wall 14, and the knob member 33 and the outer casing 31 are slightly tilted. The leading edge of the side wing 35 is locked to the opposite edge of the operation window 14b. As a result, the operation knob 30 is locked so as not to slide.

  As shown in FIG. 6, when the operation knob 30 is in the closed position, the wall 32c on the opposite side to the open position of the inner casing 32 abuts on the opposite edge of the operation window 14b. Furthermore, when the compression coil spring 34 is biased, the protruding portion 35a of the wing portion 35 on the opposite side is elastically pressed against the back surface of the front wall 14, and the knob member 33 and the outer casing 31 are in the open position. The tip edge of the protruding portion 35a of the one wing portion 35 is locked to the one edge of the operation window 14b. As a result, the operation knob 30 is locked so as not to slide.

When the knob member 33 is pushed to the back side while the operation knob 30 is in the open position or the closed position, the outer casing 31 integrally coupled with the knob member 33 is also pushed to the back side and is locked to the edge of the operation window 14b. The wing part 35 is retracted from the operation window 14b. Thereby, the lock of the operation knob 30 is released, and it can be slid left and right from the open position to the closed position or from the closed position to the open position.

  As the operation knob 30 slides left and right, the open / close plate 20 engaged with the outer casing 31 is slid left and right and rotated by the cam member 16. Thereby, the ventilation path 10a can be opened and closed.

According to the ventilation device 10, the operation knob 30 can be engaged only with the front wall 14 of the front wall 14 and the rear wall 15. Therefore, the distance accuracy between the front wall 14 and the rear wall 15 does not prevent the lock from being released, and does not prevent it from being fitted in the back of the operation window 14b, so that it can be stably opened and closed. it can. Further, the urging force of the compression coil spring 34 does not fluctuate according to the distance between the front wall 14 and the rear wall 15, and the urging force can be made constant.
Furthermore, the operation knob 30 can be applied to the ventilator 10 of another specification in which the distance between the front wall 14 and the rear wall 15 is different, and can be standardized.

The present invention is not limited to the above embodiment, and various modifications can be made.
For example, the ventilator 10 may extend up and down. The operation knob 30 may be slid up and down.
The outer casing 31 may be opened not only on the front side but also on the rear side, and the bottom portion 31g of the outer casing 31 may be omitted.
Instead of the operation knob 30 sandwiching the edge of the operation window 14b of the front wall 14 from the front and rear by the collar 32b of the inner casing 32 and the outer casing 31, the operation of the front wall 14 is operated only by the front edge of the inner casing 32. The edge of the window 14b may be engaged so as not to fall off. In that case, the outer casing 31 may be omitted. The opening / closing plate 20 may be directly engaged with the inner casing 32. The inner casing 32 may be provided with a restricting portion that restricts the forward displacement position of the knob member 33.
The elastic member is not limited to the compression coil spring 34, and may be another spring such as a leaf spring or rubber. A leaf spring portion may be integrally provided as an elastic member on the knob member 33 or the inner casing bottom portion 32d.
