A vehicle battery mounting structure includes a battery frame that is disposed at a vehicle lower side of a floor panel, and is made from resin; a ductile member that includes a main body joined to the battery frame and a flange contiguously formed at a vehicle width direction outside end of the main body, the flange having a hole, and the ductile member being fastened to a lower face of the floor panel using a fastener inserted through the hole; and a fastening portion that is formed in a region including the hole, having a substantially hat shaped cross-section profile projecting toward a vehicle upper side and having ridge lines on vehicle front-rear direction sides of the region, and the ridge lines being formed with curved or bent shape toward directions heading away from the hole on progression toward a vehicle width direction inside in plan view.

The technical problem of this invention is to eliminate the need to use deformable panel walls and to find the body of a shape that no false deformation, such as dented deformation, takes place in a portion of the body due to the hot filling of the contents or the reduced pressure created by the treatment of retort-packed foods. The object of this invention is to obtain a bottle that can inhibit the deformation caused by reduced pressure, has a high buckling strength, and is good in outer appearance. As the solution, there is provided a biaxially drawn, blow-molded bottle made of a synthetic resin, in which the surface rigidity of the wall of body is set in such a manner that a part of the body wall cannot become dented inward under a reduced inner pressure of at least 350 mmHg (46.7 kPa).

In a lower vehicle-body structure of an automotive vehicle comprising a pair of right-and-left side sills, a floor panel, and a first seat-attaching bracket supporting a front seat, an upper wall portion of the first seat-attaching bracket comprises an attachment portion to which the front seat is attached, a slant portion (connection portion) which extends downward from an outward-side edge side of the attachment portion, and a stepped-down portion which extends from the slant portion toward the side sill, and a bead which protrudes upward and extends from the slant portion toward the side sill in the vehicle width direction is provided at the stepped-down portion.

The invention provides a mounting structure for a dash cross beam at a front part of a vehicle. The mounting structure can effectively disperse the load to floor channels so as to reduce the load applied on floor longitudinal beams. Besides, the engine, engine pipes, pedals, and steering shaft are not interferenced, so that the layout freedom is ensured. The mounting structure is formed in a manner that, the dash cross beam arranged between front longitudinal beams in the width direction of the vehicle is divided into three parts, i.e., two side parts and a central part; the two side parts are engaged with a front surface side of a dash, and outer ends of the two side parts lean towards the front side of the vehicle so as to be engaged with the longitudinal beams; the central part is engaged with a rear surface side of the dash; and the sections of the joints of the central parts and the central part continuously form the joints of the two side parts and the central part of the dash cross beam on the front and rear surface of the dash.

A cowl cross member for a vehicle is provided. The cowl cross member includes a cowl cross bar that has first and second ends fixed to an interior panel of a front pillar of the vehicle and is disposed in a horizontal direction at a front side of a vehicle body, with a steering column fixed thereto. A center support is vertically disposed to support a central portion of the cowl cross bar to couple the cowl cross bar at a predetermined height and is configured to adjust a length of the center support during a vehicle collision.

The invention provides a door construction for a vehicle, and rigidity of a base portion of a window frame portion can be reliably improved through simple construction. An inner side reinforcer (22) is engaged to an inner side of a carriage supporting a window outer side reinforcer (21) of a window frame (3A), a lower portion (22b) of the inner side reinforcer is engaged to an inner plate (12), the inner side reinforcer (22) and the window outer side reinforcer (21) have an expansion surface (21b), and the expansion surface is formed at one side opposite to a door window based on the window frame (3A), wherein, an outer side reinforcer (4) has an extension portion (41) extending to the expansion surface and engaged with the inner side reinforcer (22) via the extension portion.

A degradable bearing pallet and a preparation method thereof. The pallet has an upper cover, a packing middle layer and a lower cover; a plurality of pallet support legs are disposed at the bottom of the lower cover; the lower cover is integrally molded with the plurality of pallet support legs; and the packing middle layer is filled in the lower cover and in the plurality of pallet support legs; the upper cover covers the packing middle layer and the lower cover. The middle part of the bottom of each of the pallet support legs is formed with a sunken groove; the pallet support legs in each of the rows are mutually connected through a connecting board; and each of the connecting boards is clamped in a corresponding one of the sunken grooves.

A vehicle wheel includes a rim and a sub-air chamber member attached to the rim and serving as a Helmholtz resonator that cancels air column resonance noise in a tire air chamber. The sub-air chamber member includes: a main body portion including a top plate, a bottom plate, and a side plate connecting between the top plate and the bottom plate, the main body portion defining an inner space surrounded by the top plate, the bottom plate, and the side plate and serving as a sub-air chamber; and a communication through-hole that allows communication between the tire air chamber and the sub-air chamber. The main body portion further includes a substantially cone-shaped portion formed integrally with the bottom plate and the side plate.

Provided is a tongue piece maintaining structure for a safety belt. In a rear decorative member is provided a recessed part accommodating the maintaining the tongue piece for the safety belt to prevent noise due to the tongue piece, so tongue piece in and out cannot be blocked and passenger comfotableness can be kept. In the tongue piece maintaining structure for the safety belt (1), a tongue piece (3) of the safety belt (1) is maintained when the safety belt (1) on the back seat is utilized; a vehicle door opening part (9) is arranged on a side part of the back seat; a back side lower decorative member (13) covering the inner side wall of a vehicle interior of the back seat side part is provided; a recessed part (15) is arranged on an end edge part (13a) on the vehicle door opening part (9) of the back side lower decorative member (13); an insertion port (16) is mounted on the bottom surface part (15a) of the recessed part (15); and when a tongue piece tail end metal assembling part (3b) is inserted into the insertion port (16), the tongue piece (3) is accommodated in the recessed part (15).
