An underbody for a vehicle may arrange and couple a plurality of assemblies forming the underbody in a vertically laminating structure. The underbody includes a panel assembly configured to form a floor of a vehicle interior; an upper member assembly configured to be laminated on and coupled to an upper side of the panel assembly; and a lower member assembly configured to be laminated on and coupled to a lower side of the panel assembly and coupled to a side portion of the panel assembly and a side portion of the upper member assembly

The working vehicle includes an engine installed in a front portion of a traveling machine body, and a post-processing device configured to purify exhaust gas from the engine. The post-processing device is mounted on an upper side of the engine. The engine and the post-processing device are covered with a hood. A hood shield plate is disposed on a rear surface side of the hood and covers at least the post-processing device from a rear surface. A heat insulating layer is formed between an operating seat disposed on a rear side of the hood and the hood shield plate.

In an automobile hood, sufficient panel rigidity and dent resistance of a panel are secured while achieving weight reduction. An automobile hood having panel, reinforcing member and joint that joins the panel and the reinforcing member such that the reinforcing member includes a structure formed from a plurality of units having hexagonal annular shape disposed in a close-packed arrangement. Floor of the unit has an annular end part. All of annular end part is located between first circle and second circle wherein first circle is inscribed within a first ridge line overlapping with an outer end part of the floor. Second circle is concentric with first circle and has a radius that is 60% of a radius of the first circle. Width of upper face of floor is 2 mm or more over the entire area of the annular end part in the circumferential direction of the annular end part.

In an automobile hood, sufficient panel rigidity and dent resistance are secured while achieving weight reduction. Automobile hood 1 has a panel 2, a reinforcing member 3, and a joint 4 that joins the panel 2 and the reinforcing member 3. The reinforcing member 3 includes a structure formed from a plurality of units 7 having a hexagonal annular shape disposed in a close-packed arrangement. Unit 7 has a floor 11, inclined wall 12 and top plate 13. The floor 11 is adjacent to the panel 2. Top plate 13 and panel 2 are separated from each other. The inclined wall 12 is arranged between the floor 11 and the top plate 13. A hexagonal annular first ridge line 31 of the unit 7 is located between the inclined wall 12 and the floor 11. A length L1 of one side of the first ridge line 31 is 40-75 mm.

A work vehicle includes a vehicle body frame, an engine hood, a first extendable member, and a second extendable member. The vehicle body frame is configured to support an engine. The engine hood has a cover frame coupled to the vehicle body frame so as to allow opening and closing, and an engine cover attached to the cover frame. The first extendable member is coupled to the vehicle body frame and the cover frame. The first extendable member is disposed at one end side relative to a center in a vehicle width direction of the work vehicle. The second extendable member is coupled to the vehicle body frame and the cover frame. The second extendable member is disposed at an other end side relative to the center in the vehicle width direction of the work vehicle.

A hood assembly for a vehicle comprises an outer panel, an inner panel disposed inwardly of the outer panel and defining a lower, sealing surface, a crush volume defined between the outer panel and the inner panel; and a bridging member disposed within the crush volume and configured to extend supportively between the outer panel and the inner panel. The bridging member comprises a support surface that is in supportive contact with the outer panel and support members that extend from the support surface toward the inner panel for structural support of the hood assembly.
