よる漏れを招来するおそれがある。(Problems to be Solved by the Invention) In the conventional reed valve described above, the reed 4 is fixed to the main body 1 by the tightening screw 6, and the diameter of the mounting hole bored in the reed 4 is A clearance is set between the diameter of the tightening screw 6 (for example, a clearance of 0.05 to 0.2 mm when the diameter of the tightening screw 6 is 3 mm), so when assembling, as shown in Fig. 4, A relative misalignment occurs between the lead 4 and the main body 1, and in the worst case, it may become impossible to completely close the vent hole 2 at the tip of the lead 4. The contact width becomes uneven,
There is a possibility that leakage may occur due to uneven seating force of the lead 4 with respect to the sheet member 3.

る。(Embodiment) In the embodiment shown in FIGS. 1 and 2, the main body 1
A sheet member 3 made of rubber-like elastic material adhered to the periphery of the ventilation hole 2 forms a step with respect to the surface of the main body 1 that gradually becomes higher from the attachment part of the lead 4 toward the free end side. A locking frame 7 that engages with the step of the sheet member 3 described above is formed integrally with the lead 4 so as to face the side edge and the front edge, and the lead 4 is connected to the main body 1 to form the sheet. The locking frame 7 is set so as to come into contact with the surface of the main body 1 and surround the sheet member 3 when the member 3 is contacted.

生のおそれが完全に解消される。(Effects of the invention) As described above, the reed valve of the present invention is made of an elastic plate that opens and closes the ventilation hole by being attached to the side surface of the body to which the sheet member made of rubber-like elastic material is adhered around the ventilation hole. By having a structure in which a locking frame that engages with the outer edge of the sheet member is integrally formed on the outside of the manufactured lead, the locking frame does not engage with the outer edge of the sheet member when the lead and main body are assembled. At the same time, the relative posture of the reed with respect to the main body is regulated, so that the risk of leakage caused by assembly misalignment between the reed and the main body, which was observed in conventional reed valves, is completely eliminated.

らされる。 In the illustrated embodiment, a locking frame that engages with the periphery of the sheet member is formed to surround the lead, but the free end side of the lead is removed and both sides are sandwiched. However, the same effect will be achieved.
また、シート部材がリードの固定側から自由端
側へ向つて高さを次第に増加させているが、本体

ても差しつかえない。 In addition, although the height of the sheet member gradually increases from the fixed side of the lead to the free end side, a step is formed with respect to the surface of the main body, and the locking frame becomes lower toward the surface of the main body. If so, there is no problem even if they are the same height.
