Problems solved by technology

Therefore, there is a problem that in addition to the variation in the size of the parts, it is also necessary to consider the variation in the tightening torque of the lock nuts 104a, 104b, 204, and it is difficult to manage
[0017] Furthermore, when a metal part is charged, a discharge is caused from the charged metal part to the conductive member, which may cause damage to the fuel tank or surrounding members.

[0045] figure 1 It is a cross-sectional view showing a structure for sealing the opening 1k of the fuel tank 1 of the vehicle according to the first embodiment of the present invention.

[0046] The fuel tank 1 of a vehicle such as a four-wheeled vehicle according to the first embodiment has a structure in which the opening 1k is blocked and sealed by the cover body 3f of the pump module 3 constituting the cover.

[0047] In the pump module 3, the cover body 3 f functions as a cover of the fuel tank 1, and a pump (not shown) that draws fuel in the fuel tank 1 is suspended.

[0048] In the fuel tank 1, a cylindrical portion 1 d is formed in the vicinity of a circular opening 1 k blocked by the pump module 3. The cylindrical portion 1d is formed integrally with the fuel tank 1 so that the material is double-folded in the radial direction toward the outside.

[0049] The cylindrical portion 1d has a locked portion 1a that locks the pump module 3, and a sealing portion 1b that forms a se...

[0076] Figure 5 It is a cross-sectional view showing a structure for sealing the opening 21k of the fuel tank 21 of the four-wheeled vehicle according to the second embodiment.

[0077] The sealing structure of the fuel tank 21 of the four-wheeled vehicle of the second embodiment is based on the structure of the first embodiment. The cylindrical portion 21d formed in the vicinity of the opening 21k of the fuel tank 21 is formed in the locked portion The double-layer shape of the reinforcement member 24 is sandwiched between 21a and the sealing portion 21b.

[0078] The other configuration is the same as the configuration of the first embodiment, so the reference numerals added to the components of the first embodiment are indicated by adding 20, and detailed descriptions thereof are omitted.

Abstract

A sealing structure of a fuel tank includes: a hollow circular cylinder part, having an inner circumferential part, formed near opening of the fuel tank to extend outward; a cap body having a hollow cylindrical part inserted into the inner circumferential part to face the inner circumferential part; and a seal member disposed between the inner circumferential part and the hollow cylindrical part. A protruding part is provided on an outer circumferential side of the hollow circular cylinder part of the fuel tank. A locking part formed on an outer circumferential part of the cap body and the protruding parts are fixed.

Description

Technical field [0001] The present invention relates to a fuel tank sealing structure that seals an opening of a fuel tank of a four-wheeled vehicle, and a vehicle provided with the fuel tank sealing structure. Background technique [0002] In the prior art, as a sealing structure for an opening blocked by a lid of a fuel tank of a four-wheeled vehicle, the following Figure 8 ~ Figure 10 The structure shown. [0003] Figure 8 ~ Figure 10 It is a cross-sectional view of a main part showing the cap of the fuel tank of the conventional vehicle and the sealing structure of the fuel tank body. [0004] For example, such as Figure 8 Of (a), Figure 8 As shown in each figure of (b), there is a structure in which the screw shapes 101na, 101nb are formed during blow molding of the resin fuel tanks 101a, 101b, and the gaskets 102a, 102b and parts 103a, 103b (mostly In this case, the pump module of the pump that draws up fuel is suspended and tightened with lock nuts 104a and 104b made of res...
