Abstract: There is provided a structure of a vibration insulating member for firmly fixing the member between a fuel tank mounted on a vehicle body by means of a tank band and the vehicle body. The vibration insulating member includes an engaging protrusion that is fixed to a fixing hole that is made through the vehicle body in a direction orthogonal to a direction in which the tank band is fastened.

Abstract: A portion of the plastic container T where an opening 7 is provided has a flange portion 7a, and provided are a recess provided annularly along a peripheral edge of the opening 7 at an outside of the plastic container body 2, with an annular member being embedded integrally in the recess, a cover 1 resting against the flange portion to close the opening 7, a seal 14 provided between the flange portion 7a and the cover 1 to prevent a leak, and an annular retainer 9 fastened to the annular member 8 while resting against an external surface of the cover 1. This allows the opening 7 provided in the plastic container T and the cover 1 to be fastened together firmly with excellent and stable hermetical sealing performance.

Abstract: In a fuel vapor processing system, a float valve and a check valve are provided in upper parts of a fuel tank to conduct fuel vapor to a canister via a fuel vapor passage. The check valve includes a low set-pressure valve and high set-pressure valve, and operates in two stages so that the internal pressure of the fuel tank can be favorably controlled by the opening of the low set-pressure valve when the fuel tank is being filled to full so that the sensor associated with the fill nozzle can successfully detect a tank full state, and any excessive rise in the internal pressure of the fuel tank typically caused by a high temperature of the surrounding environment can be avoided by the opening of the high set-pressure valve.

Abstract: A waterproofing member accommodated in the interior of a vehicle body frame having a closed cross section is constructed such that an upper end portion of a tube portion is covered with an inverted cup-like lid which opens on a bottom side thereof and that the height Hc of an opening below the bottom side of the lid is set lower than the height Hp of an end portion of the tube portion. Accordingly, even if the end portion of the tube portion and the lid are submerged, air captured within the lid can prevent the rise of the level of water to prevent the penetration of water into the tube portion.

Abstract: A fuel tank and a canister are connected to each other by a first evaporated-fuel passage and a second evaporated-fuel passage, and a valve chamber of a float valve separate from the fuel tank is disposed at an intermediate portion of the first evaporated-fuel passage. Thus, there is no limitation in the positional relationship between a filled-up liquid surface in the fuel tank and a valve seat of the float valve. Therefore, it is possible to reduce the vertical dimension of the float valve. Moreover, since the valve chamber is provided separately from the fuel tank, it is unnecessary to define an opening for mounting the valve chamber to the fuel tank.

Abstract: The waterproofing member 25 accommodated in the interior of a vehicle body frame 29 having a closed cross section is constructed such that an upper end portion of a tube portion 31 is covered with an inverted cup-like lid 41 which opens on a bottom side thereof and that the height Hc of an opening below the bottom side of the lid 41 is set lower than the height Hp of an end portion of the tube portion 31. Accordingly, even if the end portion of the tube portion 31 and the lid 41 are submerged, air captured within the lid can prevent the rise of the level of water to prevent the penetration of water into the tube portion 31.
