Description

[Detailed Description of the Invention] The present invention relates to an oil cap, and particularly to an oil cap whose main purpose is to prevent leakage of gas generated in a tank.

Therefore, the present invention has a cap body 1, a spring plate 2 attached to the body 1, a fixing piece 3 of the spring plate 2, a locking leg pipe 4 suspended from the center of the body 1, and a tank cap m. The spring plate 2, which is crimped from the inside and inserted into a horizontal hole 5 provided in the locking leg tube 4, has an engagement hole 6 for the fixing piece 3 in its center, and is locked through the engagement hole 6. The fixing piece 3 that fits into the lower end of the leg pipe 4 is an oil cap characterized by integrally provided with protrusions 3 a and 3 b that engage with the horizontal hole 5 .

In the illustrated embodiment, the fixing piece 3 is formed in a substantially retrograde shape, and the triangular protrusions 3 a and 3 b on both sides are not structured to have elasticity, and the locking leg tube 4 is square and has a spring structure. The engagement hole 6 of the plate 2 and the hole 8 of the separator 7 placed thereon are also squared to fit into the horizontal hole 5 of the locking leg tube 4,
Fit the fixing piece 3 into the locking leg tube 4 through the engagement hole 6, and
3b is locked in the horizontal hole 5, the spring plate 2 has a central portion 2a and both ends 2b, 2C formed into a cross-sectional shape to provide strength, and both ends 2b, 2C are suspended from the inner peripheral surface of the cap body 1. A notch 1b in 1a protrudes through the IC and is pressed into contact with the tank mouthpiece m from below.

The central part 2a fits into the horizontal hole 5 to stop vertical vibration, the notch 1b is wide, and the notch 1C is narrow so as to fit into one end 2C of the spring plate 2, and the wide notch 1b connects the spring plate 2. is inserted into the horizontal hole 5 and fitted into the narrow notch 1C to prevent left and right rotation.

Reference numeral 9 indicates a backing, 10 indicates a vent provided in the cap body 1, and 11 indicates a vent provided in the separator.

Since the present invention has the above-described structure, there is no risk of the screws falling off due to deterioration of the resin, unlike the conventional method in which the spring plate is fixed to the cap body using set screws, and the cap can be fixed easily and reliably. The tightening process can also be omitted, which has the effect of reducing costs.
