Abstract: A lamp body includes a housing to be attached to a vehicle body, and a lens joined to the housing. The lens includes a heat-generating region that allows for heat generation.

Abstract: A pressure tank includes a resin liner, a base, a seal, and a collar. The resin liner contains fluid therein. The resin liner has a tubular portion via which an inside of the resin liner communicates with an outside of the resin liner. The base includes a supply/discharge hole in which the tubular portion is inserted. The seal is provided between the tubular portion and the base in the supply/discharge hole. The collar has a through-hole and inserted into the tubular portion.

Abstract: A hydrogen storage container has an inner side resin layer that comes into contact with hydrogen gas that is introduced into the container, a barrier layer which is disposed on the outside of the inner side resin layer and which prevents permeation of hydrogen gas, and an outer side resin layer comprising a resin. Among these layers, the inner side resin layer comprises a polyethylene-based resin, and if the thickness of the barrier layer is denoted by Y and the thickness of the inner side resin layer is denoted by X, the thickness X satisfies formula (1). Moreover, D in formula (1) is the diffusion coefficient of the polyethylene-based resin, as determined by means of a differential pressure method at 50° C.

Abstract: A vaporized fuel processing device attached to a fuel tank, includes a casing for forming an outer shell of the vaporized fuel processing device, a diaphragm valve unit opened at the time of increasing the pressure in the fuel tank, and a vent passage communicating with atmospheric air. In the vaporized fuel processing device, the diaphragm valve unit is disposed in a space formed in the casing.

Abstract: A joint part includes a connection part weldable on the tank and a tube part including an inner circumferential face. An inner tube is fitted inside and in contact with the inner circumferential face. The tube and the inner tube include materials having different swelling rates when exposed to the fuel to be stored in the tank. An end of the tube, and an end of the inner tube corresponding in an axial direction with the end of tube, include slopes therearound in contact with each other. The slopes are inclined from the axial direction. When the tube and the inner tube swell due to being wet with the fuel, the slopes have a relative displacement in the axial direction and in a radial direction of the tube and the inner tube, with contact therebetween.

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: A joint part includes a connection part weldable on the tank and a tube part including an inner circumferential face. An inner tube is fitted in the inner circumferential face and in contact with the inner circumferential face. The tube and the inner tube include materials having different swelling rates against a fuel to be stored in the tank. An end of the tube and a corresponding end of the inner tube in an axial direction of the tube and the inner tube include slopes therearound in contact with each other. The slopes are inclined from the axial direction. When the tube and the inner tube swell due to wet with the fuel, the slopes have relative displacement in the axial direction and a radial direction of the tube and the inner tube with contact therebetween.

Abstract: In order to solve the problem of a conventional attachment structure of a fuel tank made of resin, the present invention is an attachment structure of a component of a fuel tank made of resin where a connection portion with a tank main body made of resin is formed of a thermally depositable material, and which tank comprises a joint portion connected with the tank main body by a thermal deposition and an inner tubular member supported by the joint portion and housed in the tank main body, wherein a movement regulation mechanism for regulating a movement in an axial direction of the inner tubular member for the joint portion is provided at least at one of the joint portion and the inner tubular member, and the joint portion and the inner tubular member are formed by an integral molding.

Abstract: A grounding structure of a fuel tank equipped with a lid body closing an opening of the fuel tank made of resin is characterized by being equipped with a ring-shaped member made of metal fixed on the periphery of the opening, and a retainer made of metal fixing the lid body on the ring-shaped member, wherein an electrically grounded member in the vicinity of the lid body is electrically connected to at least one of the ring-shaped member and retainer, and grounding is performed through at least one of the ring-shaped member and retainer.

Abstract: An on board refueling vapor recovery system includes a first fuel vapor passage for connecting a fuel tank with a canister, a second fuel vapor passage for connecting an inlet portion of a fuel filler pipe with the fuel vapor passage (a tank main body) and a check valve in the second fuel vapor passage. The check valve is integrated with a first quick connector of a resin hose (a resin tube) which constitutes the second fuel vapor passage. Therefore, the number of man hours required for assembling the on board refueling vapor recovery system can be reduced. In addition, the space required for installing any of the on board refueling vapor recovery system can also be reduced. Furthermore, the amount of released fuel evaporative emissions or fuel evaporative emissions can be reduced.

Abstract: An earthing structure of a fuel tank equipped with a lid body closing an opening of the fuel tank made of resin is characterized by being equipped with a ring-shaped member made of metal fixed on the periphery of the opening, and a retainer made of metal fixing the lid body on the ring-shaped member, wherein an electrically earthed member in the vicinity of the lid body is electrically connected to at least one of the ring-shaped member and retainer, and earthing is performed through at least one of the ring-shaped member and retainer.
