えば「ピン」などによる固定も含むものとする。<Problems to be solved by the invention> As can be seen in the above-mentioned publications, various ideas have been devised for stopper members of vent caps, but each has its advantages and disadvantages, and no one is the best. Among these, there is a known vent cap 1 having a structure in which a stopper member 4 consisting of an elastic part 2 and a fixing part 3 is riveted via the fixing part 3 (Fig. 3). Although this riveted type has the advantage of having a simple shape and structure and is easy to attach to the fitting part, the attachment condition to the fitting part is somewhat unstable, that is, it is only riveted. Since it is easy to swing as shown by arrow A using this riveted rivet 5 as a fulcrum, it may not be oriented correctly between the fitted part and the ventilation duct, and there is a risk that a reliable reinforced state cannot be obtained. There was a disadvantage that there was. Although this problem does not occur if riveting is performed at multiple locations, this is not preferable from the viewpoint of processing costs. In FIG. 3, 6 is the vent cap body, 7 is the fitting part, and 8 is the ventilation duct.
In addition, in this specification, "riveting" means
Fixation is not limited to so-called "rivets," but also includes fixation using, for example, "pins."

そこで、この考案では、リベツト止めが１箇所

る。 Therefore, this invention aims to provide a riveted type stopper member structure in which the above-mentioned swinging does not occur even when riveted at one location.

を要旨としている。<Means for solving the problem> Specifically, a stopper member of a vent cap is provided, in which a stopper member consisting of an elastic part and a fixing part is riveted to a fitting part of the vent cap main body via the fixing part. In the structure, regarding the fixing part and the fitting part, a concave/convex engagement between a protrusion provided on either the fixing part or the fitting part and a protrusion receiver provided on either the fixing part or the fitting part. The main purpose is to form a

Therefore, the above-mentioned swinging of the head is prevented.

is riveted with a rivet 5 via the fixing portion 14, and a concave/convex engagement 16 is formed adjacent to the riveted portion. This concave/convex engagement 16 is connected to the rivet hole 1 of the fixing part 14.
A protrusion 18 provided adjacent to the rivet hole 19 of the fitting portion 12 is similarly formed by engaging with a protrusion receiver 20 provided in the form of a through hole. Of course, "protrusion" and "protrusion receiver"
Since it is sufficient that they are paired with each other, it does not matter whether they are provided on either the fixing part 14 or the fitting part 12. Further, its shape is not limited to the warp shape as shown in the figure, but may be elongated or other shapes, for example,
Further, the "protrusion receiver" does not need to be in the form of a through hole.

る。 In this way, in this stopper member structure, since the concave/convex engagement 16 between the protrusion 18 and the protrusion receiver 20 is formed adjacent to the riveted area, this concave/convex engagement 16 It becomes a second fixing point for the riveting as a fixing point, and as a result, two fixing points are formed, so
This will prevent the above-mentioned swinging of the head.

In the stopper member structure of the vent cap, a concave/convex engagement is formed between the fixing part and the fitting part by a protrusion and a protrusion receiver with which this protrusion can freely engage, so that riveting is not possible. It has the excellent effect of reliably preventing the head from swinging even in one place.
