Disclosed herein is a connecting arm for vehicles made of reliable composite materials that is light-weight, which has strength to withstand both tension and compression forces, and which can be manufactured easily and cost-effectively. The present invention includes an inwardly protruding embossed part formed on structural plate having at least a pair of metal thin plates provided to face each other. A concave part which is formed on outer side surfaces of an intermediated member is fitted onto the embossed part, so that, when torsional, tensile, or compressive forces are applied by axial members (J1 and J2) to the connecting arm for vehicles. the structural plates provide strength primarily against tensile forces. The intermediate member and external plate members are both made of plastic materials that provide strength against compressive forces, and the intermediate member and structural plates provide strength against torsional forces, respectively.

A rear end of a torsion bar is fixed to a distal portion of a spring plate so that the rear end of the torsion bar is in a position other than front to rear direction of a cross member. Thus, when a load is applied to the suspension system in the front to rear direction, the spring plate elastically deforms in this direction. Therefore, the suspension system can prevent the torsion bar from directly contacting the cross member. Also, the suspension arm has two arm portions each of which is supported by two pivot portions. The body has sufficient rigidity against a load applied in the lateral direction thereof. When a load is applied in the front to rear direction, the spring plate elastically deforms, thereby moving the suspension system in this direction. When a load is applied in the vertical direction of the body, the torsion bar twists. With this reaction force, a suspension force takes place and the spring plate bends. Thus, an excessive bending force is not applied to the torsion bar.

[Object] Provided are a press-molded product in which the plank pieces can be appropriately matched with each other and the weight of the product is not increased even when the plank pieces can be appropriately matched with each other, and a method of manufacturing the same.[Solving Means] The present invention is a press-molded product (100) formed by bending a blank (B) to divide the blank into a first plank piece (10) and a second plank piece (20) with a bending portion interposed therebetween and making the first plank piece and the second plank piece come into contact with each other through the bending. The first plank piece and the second plank piece include punching portions (11, 21) formed by punching the blank, and a first rising portion (12) and a second rising portion (22) formed by raising the rims of the punching portions. There is provided a positioning portion (40) that positions the first plank piece and the second plank piece by engaging the first rising portion of the first plank piece with the second rising portion of the second plank piece.

Provided is an attaching device that can convey a component, such as a nut, to a portion to be welded without using an air cylinder.The present invention provides an attaching device (100) that attaches a nut (240) to a bracket (230). The attaching device (100) has a component feeding part (10) that stores the nut therein, a welding part (40) that welds the nut to the bracket by using electrodes (41, 42), a conveying part (20) that conveys the nut stored in the component feeding part to a position where the nut is to be attached to the bracket, and a feeding head (30) that temporarily positioned between the electrodes (41, 42) and that places the nut conveyed from the conveying part on the lower electrode of the pair of electrodes.

A hollow component made of thin sheet metal members is described, along with a method of manufacturing such hollow component. The method involves applying a flow drilling process on one sheet metal member of a pair of sheet metal members having a gap G between them to form a first collar part. A flow drilling process is applied on the other sheet metal member of the pair to form a second collar part as well as to cause an inner tip of the second collar part to fuse with an inner tip of the first collar part. A cylindrical connection member is formed to strengthen a flat sheet metal members.

A cross member extends in a vehicle width direction and has opening portions at end portions in the vehicle width direction. The cross member includes a cross member main body, a closing plate, and a cylindrical spacer. The end portion of the cross member main body in the vehicle width direction includes a recessed portion on a side of the cross member main body opposite to a side on which the cross member main body is opened, the recessed portion being recessed toward the inner surface side.

Disclosed herein is a suspension arm component for vehicles with sufficient strength or rigidity to withstand repetitive compressive and tensile forces, and a method for manufacturing such a component by pressing or hemming process alone, without recourse to any welding process, forming quickly and simply, a process with advantages in terms of material yield and cost. The suspension arm component for vehicles includes first flange pieces as well as second flange pieces, and a pair of half members, each having a hat-like shaped cross-section perpendicular to its axis, are joined together to protrude the first flange part and the second flange part from an expanded part, where both the first flange part and the second flange part extend linearly along the axis of the main body part. The main body part presents a rectangular shape in its side view.

Disclosed is a suspension subframe (1) in which highly rigid side-end members (10) are attached to opposite side end sections of a flat plate-like main body member (2) so as to extend in the front-rear direction of a vehicle. The subframe (1) has extremely high rigidity against forces acting thereon from the front, rear, left, right and the like with the aid of the side-end members (10). The subframe (1) makes it possible to cut out materials with almost zero waste, and is made lightweight and inexpensive.
