Benefits of technology

[0010] An object of the present invention is to provide a fuel filler cap which leads the operator to fasten the cap with fastening torque of a predetermined level or higher.

Problems solved by technology

In this type of fuel filler cap, however, since the space for indicating letters is limited, letters may inevitably be small.
Therefore, even if the fuel filler cap bears the letters instructing the operator to fasten the cap by fastening torque of a predetermined level or higher, if a car user (operator) having little knowledge of cars is refilling the car in a self-service gas station or the like, it is difficult for the operator to recognize the contents of the indication of the closing operation within a short period of time.

first embodiment

[0018] A first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

[0019]FIG. 1 shows a part of a rear side of a vehicle, for example, a car. In FIG. 1, a reference numeral 1 denotes a car body. A fuel opening portion 2 is formed in a panel portion forming the rear side of the car body 1. A fuel lid 3 opens and closes the fuel opening portion 2. A fuel filler neck bracket 4 is attached to an interior of the fuel opening portion 2. A fuel inlet 5 is formed in a bottom portion of the bracket 4. The fuel inlet 5 communicates with a fuel tank (not shown) via a fuel filler neck 6 and a filler hose (not shown). The car is refueled through the fuel inlet 5. A female screw portion 7 is formed in the inner surface of an end portion of the fuel filler neck 6 connected to the fuel inlet 5.

[0020] A fuel filler cap 10 closes the fuel inlet 5. The cap 10 has a main body 10a as a filler cap main body. The main body 10a has, for example, a screw portion 12 and an...

second embodiment

[0031]FIG. 3 shows a second embodiment of the present invention.

[0032] In this embodiment, for example, a propagation symbol 40, representing that sound is propagated from one point, is used as the sound generation symbol 33. The illustration portion 30 made up of the propagation symbol 40, the main body shape portion 31 and the arrow portion 32 also provides the same effect as that in the first embodiment.

third embodiment

[0033]FIG. 4 shows a third embodiment of the present invention. In this embodiment, for example, a speaker symbol 45, representing that sound is generated from a speaker, is used as the sound generation symbol 33. The illustration portion 30 made up of the speaker symbol 45, the main body shape portion 31 and the arrow portion 32 also provides the same effect as that in the first embodiment.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This non-provisional application incorporates by reference the subject matter of Application No. 2005-176571 filed in Japan on Jun. 16, 2005, on which a priority claim is based under 35 U.S.C. §119(a). BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a fuel filler cap, which closes a fuel inlet of, for example, a car. [0004] 2. Description of the Related Art [0005] Generally, a fuel inlet of a car is closed by a fuel filler cap, which is screwed after fueling, as disclosed in, for example, Jpn. Pat. Appln. KOKAI Publication No. 11-254979. [0006] To prevent fuel from leaking from the fuel inlet, the fuel inlet need be closed by a fuel filler cap securely. [0007] To securely close the fuel inlet, a technique provides a fuel filler cap incorporating a click generating portion. In this art, when the fuel filler cap is screwed in by a predetermined amount, an operation handle portion in the...
