〔考案の目的〕
（産業上の利用分野）
本考案は、自動車などの車室内から車室外に空
気を導く車輌用換気装置に関する。[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a ventilation system for a vehicle that guides air from the interior of a vehicle such as an automobile to the outside of the vehicle.

るようにしている。(Prior art) Conventionally, as a vehicle ventilation system that guides air from the interior of a vehicle to the outside of the vehicle, for example,
As shown in Publication No. 56-63613, a vent is formed in a panel of the vehicle body, and a valve body made of a sheet of rubber, synthetic resin, etc. is fixed at the top of the vent to the outside surface of the vent. If the pressure inside the vehicle or trunk increases when the door or trunk lid is closed, the valve body opens, allowing air to escape outside the vehicle, and when the air pressure inside and outside the vehicle becomes the same, the valve body returns to its original position. I'm trying to go back.

なお、バルブ体を極めて薄いシートで形成した場
合には、高温雰囲気下ではバルブ体が変形し、密
閉性が悪くなるという問題がある。 However, in such a structure, if the valve body is made of a plate-shaped sheet made of rubber or synthetic resin, when the valve body opens, the bending resistance of the sheet causes the valve body to open near the upper mounting part. If the pressure difference between the inside and outside of the vehicle is small, the valve body will hardly open and there will be no ventilation.
Note that when the valve body is formed of an extremely thin sheet, there is a problem that the valve body deforms in a high temperature atmosphere, resulting in poor sealing performance.

(Means for Solving the Problems) The present invention provides a valve body that allows air to flow only from the interior of the vehicle to the outside of the vehicle at the vent 14 of the valve frame 13 that communicates the interior and exterior of the vehicle. 16, the above-mentioned valve body 16
The peripheral frame 17 is inserted into a flat cylindrical thin film 18 made of heat-shrinkable synthetic resin, the thin film 18 is stretched over the peripheral frame 17, and the upper part of this thin film 18 is fixed to the valve frame 13. It is suspended from the vent 14 so as to be openable and closable.

る。(Function) According to the present invention, the valve body 16 rotates to open and close at the fixed portion formed by the thin film 18 due to the pressure difference between the inside and outside of the vehicle compartment.
It is very light because it is composed of 8 and
Since the bent portion is the thin film 18 itself, there is little opening resistance, and when the internal pressure of the passenger compartment is higher than the external pressure,
Even if the differential pressure is small, it opens easily.

くことができる。 In the above configuration, if there is no pressure difference between the inside and outside of the vehicle compartment, or if the external pressure is greater than the internal pressure, the vehicle will remain closed due to its own weight or due to its own weight and external pressure, as shown in Figure 1. On the other hand, when the internal pressure is greater than the external pressure, as shown in FIG. 2, even if the differential pressure is small, the valve body 16 is made up of a thin peripheral frame 17 and a thin film 18, so it is very light. Moreover, since the bent portion is the thin film 18 itself, there is almost no bending resistance and it can be opened easily.

性を高めることができる。 Further, a projecting edge 15 is provided along the opening edge of the vent 14 of the valve frame 13, and the valve body 16 abuts against the projecting edge 15 inside the peripheral frame 17, so that the projecting edge 15 and the thin film 18 are connected to each other. The sealing performance can be improved by the contact between the two.

According to the present invention, when forming a valve body, the peripheral frame is simply inserted into a flat cylindrical thin film made of heat-shrinkable synthetic resin and heated, and the thin film is integrated into the peripheral frame. Since it can be stretched, the valve body can be manufactured extremely easily and at low cost.

性を高めることができる。 In addition, by making the valve body into a sheet with a synthetic resin thin film stretched around the peripheral frame, the valve body is extremely light, and moreover, the valve body is suspended by the thin film and placed on the outer surface of the valve frame. Therefore, the bending part has little opening resistance due to the thin film itself, and when the internal pressure of the passenger compartment is higher than the external pressure, it opens easily even if the differential pressure is small, opening and closing the valve body smoothly and reliably. Ventilation can be improved, and the valve body does not lose its shape due to the surrounding frame. Even if an extremely thin thin film is used, the thin film is double bag-shaped, so the valve body does not lose its shape due to the surrounding frame. The portion fixed to the frame is also strong enough to maintain its shape stably and improve airtightness.
