A vehicle body structure includes a roof structure and a lateral side structure, wherein the roof structure includes a roof panel fastened to an underlying roof reinforcement frame, wherein the lateral side structure includes a side panel fastened to an underlying side support structure, wherein a lateral side of the roof panel is fastened to the roof reinforcement frame by means of a hemming joint that is formed by folding a lateral side of the roof panel around an edge of the roof reinforcement frame, and wherein a folded side edge of the roof panel is fastened to the side panel by means of an elongated laser brazing joint.

An undercover (31) for rectifying airflow under a floor of a vehicle while driving the vehicle includes screw pedestals (42) for fixing screws (41) or nut pedestals for nuts, which are served as fastening points to a vehicle body (29). Interference caps (58) which are a molded product made from an elastic resin material are fitted between the adjacent pedestals. Under a state that the undercover (31) is engaged with and is attached to the vehicle body by the screws, a top portion (60) of the interference caps (59) is elastically deformed and is abutted to the opposite vehicle body surface, and the above abutment is maintained. Small clearance between the undercover and the vehicle body are maintained, and interference between the undercover and the vehicle due to vibration while driving is prevented, without changing the number of fastening points of the undercover to the vehicle body.

A grommet mounted to a through hole formed in a vehicle body panel includes an inner cabin side harness insertion portion that projects toward an inner cabin side through which a wire harness penetrate, an outer cabin side harness insertion portion that projects toward an outer cabin side through which the wire harness penetrate, a lip mountain integrated with the inner cabin side harness insertion portion, a panel abutting portion that abuts on a periphery of the through hole on an outer cabin side of the vehicle body panel, a connection portion that connects the lip mountain and the panel abutting portion, a working portion formed across the outer cabin side harness insertion portion and the panel abutting portion, a work pressing portion integrated with the outer cabin side harness insertion portion and the working portion, and a pressing surface portion that is integrated with the work pressing portion and protrudes toward the lip mountain.

A method of manufacturing a vehicle body is disclosed. A frame member is formed to have a tubular shape in an open cross-sectional structure in which one side surface thereof is opened and a fastening portion is formed in a shape to close an opening portion at an end of the frame member. The fastening portion and the frame member are formed so that the fastening member closes the opening portion at the end of the frame member and the fastening portion is configured to be fastened to another frame member by a fastener in a surface-contact state.

A vehicle cabin structure includes a pillar constituting a framework of a vehicle cabin, and a pillar trim which is an interior member arranged with a clearance from a vehicle cabin inside facing surface of the pillar and covering the vehicle cabin inside facing surface of the pillar. The pillar trim has, in its surface facing toward inside of the vehicle cabin, a slit extending along the pillar.

A vehicle frame and a mobile crane having such a vehicle frame includes a first frame part and a second frame part which can be detachably connected to each other via a common interface. The interface includes multiple points at which it is bolted to bolting elements assigned to the respective frame parts. The interface also includes at least one profile along which it engages with engaging elements assigned to the respective frame parts which, when the bolting elements are aligned with each other, are in a mutually positive-fit engagement across their extent.

A chassis frame for an electric vehicle may include: a first frame and a second frame spaced apart from each other in a longitudinal direction of the electric vehicle; a center frame disposed between the first frame and the second frame, and configured to have side members spaced apart from each other in a widthwise direction of the electric vehicle; a first fastener which extends from the first frame, and is fastened to a first side of the side member; and a second fastener which extends from the second frame, and is fastened to a second side of the side member, wherein the first fastener and the second fastener are configured to be in contact with entire peripheries of the side member.

A radiator support assembly may include a radiator support upper member including an upper internal surface, a radiator support side member including a side internal surface and provided in pairs, and a radiator support lower member including a lower internal surface, wherein the radiator support upper member, the radiator support side member and the radiator support lower member are joined so that the upper internal surface, the side internal surface and the lower internal surface form a single closed-loop.

A multi-functional coupler for one or more vehicle components includes a shank, a head connected to the shank, a connector carried by the shank, and a tool. The tool is carried by the head or shank spaced from the connector, and the tool has a fastener engaging portion by which a fastener may be moved to install or remove the fastener from a component. The coupler may be used to both coupled together two or more components, and to remove fasteners or other connections via the tool of the coupler. Conveniently, as the coupler is normally installed on the vehicle to couple together two or more vehicle components, the coupler is readily available to a user wanting to remove fasteners compatible/drivable with the tool of the coupler.

A vehicle includes a first vehicle component, a second vehicle component, and a fastener assembly. The first vehicle component has a first side defining a first opening and a second side opposite the first side defining a second opening. The second vehicle component is disposed between the first and second sides of the first vehicle component. The fastener assembly attaches the first and second vehicle components to each other and includes a sleeve, a bushing, and a fastener. The sleeve is disposed within the first opening of the first vehicle component. The bushing extends through the second vehicle component and is disposed between the first and second sides of the first vehicle component. The fastener extends through the sleeve, the bushing and the first and second openings of the first vehicle component.
