ヤラリ本体を固定した換気ギヤラリの取付け装置
の構成としたものである。Structure of the invention In order to achieve the above object, the present invention deflects the tip of an elastic strip outward, and inserts a V-shaped slit in the middle of the strip so that the tip becomes sharp. A mounting device for a ventilation gear including a mounting piece with claws, the rear end of the mounting piece being attached to the body of the ventilation gear body, and the mounting piece being press-contacted to the inner surface of a duct to fix the ventilation gear body. The structure is as follows.
すなわち、ダクトの内面に圧接して換気ギヤラ
リを取付ける先端の鋭利な爪部が換気ギヤラリを
ダクトに取付けまでは取付片の表面から飛び出さ
ないように構成するものである。 That is, the sharp claw portion at the tip, which attaches the ventilation gear by pressing against the inner surface of the duct, is configured so that it does not protrude from the surface of the attachment piece until the ventilation gear is attached to the duct.

のである。 In the figure, reference numeral 1 denotes a ventilation gear body, which has an inclined rainproof plate 2 provided at the front to prevent rain from entering, a flange portion 3 approximately in the center, and a body portion 4 at the rear. A plurality of attachment pieces 5 are attached to the outside of the body 4. This mounting piece 5 is made of a band-shaped elastic plate, and one end is deflected outward, and a narrow V-shaped slit 6 is inserted in the middle part to form a sharp claw 7 toward the tip. The relationship between the dimension A of the base of the claw 7 and the dimension B from the base of the claw 7 to the end of the band plate is 2B<A. Therefore, the tip 9
When a force in the direction of arrow M is applied to , the portion D is deformed and the claw 7 is shaped to protrude. Note that 8 in the figure indicates a mounting hole. When the body 4 of the ventilation gear body 1 having the above configuration is inserted into the duct 10, the body 11 is inserted.
It is fixed by the elasticity of the mounting piece 5, and when force is applied in the direction of removal, the tip of the claw 7 gets wedged in the duct 10, preventing it from coming off and ensuring reliable attachment. Further, normally, the claws 7 do not protrude as shown in FIG. 3, so there is no chance of injury during handling.

帯板の中間部にＶ状のスリツトによつて帯板の先
端側に尖鋭部が向いた爪を形成し、帯板の先端に
圧接力が加わることにより爪の先端が帯板の表面

片の表面より飛び出していないので爪により怪我
をすることがなくなる。Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, the tip of the elastic strip is deflected outward,
A V-shaped slit in the middle of the strip forms a claw with a sharp point facing the tip of the strip, and when pressure is applied to the tip of the strip, the tip of the claw pops out from the surface of the strip. Since the mounting piece is formed like this,
The claws do not protrude beyond the surface of the mounting piece until the ventilation gear is attached to the duct, so there is no chance of injury from the claws.
