A welding structure of a press-formed part made by combining and joining two parts formed by press-forming and each having an opening portion on at least one side of a cross-section, while the opening portions face each other, and includes a step portion that is provided by forming a bent projection projecting outwardly on a tip end portion of a side wall portion of a lower side part, partially or entirely on a joining surface. A tip end side of the step portion is fitted into the opening portion of an upper side part, and the step portion of the lower side part and the tip end of a side wall portion of the upper side part are linearly joined by arc welding.

A vehicle of an embodiment includes a driving device including a rotating electric machine, a case configured to accommodate the rotating electric machine and a PCU that is disposed on a side opposite to a side at which a load is input when the vehicle collides with an object, that is disposed in front of the case and that is configured to supply electric power to the rotating electric machine, a support section that is provided in the driving device and that is configured to come in contact with a vehicle body frame of the vehicle, and an impact attenuating section that is provided on the support section and that is configured to attenuate an impact when the vehicle collides with an object.

A vehicle frame structure capable of achieving light weight, improving structural rigidity, and providing a good casting and forming effect is provided. The vehicle frame structure includes a pair of side portions and a connecting portion. The pair of side portions extends in a vehicle front-rear direction and is mounted on a vehicle body. The connecting portion is arranged as an elongated structure having a pair of long sides and is connected between the pair of side portions. The pair of side portions and the connecting portion are integrally formed by casting through injecting of molten metal from one side of the pair of long sides of the connecting portion. The connecting portion has a film surface connecting the pair of side portions and has a plurality of elongated holes extending radially from the center of the film surface towards the other side of the pair of long sides.

A profile includes two end wing portions with substantially a transversal direction (Y), two lateral wall portions having substantially a height direction-(Z), a frontal wall portion having substantially a transversal direction (Y), two curved transition zones (R1, R2) disposed between the lateral wall portions and the frontal wall portion, and two curved transition zones (R3, R4) disposed between the end wing portions and the lateral wall portions. A specific portion of each curved transition zones (R1, R2) between the lateral wall portions and the frontal wall portion has a tensile strength lower than the tensile strength of the rest of the cross-section. This configuration also relates to a longitudinal beam, a cross-member, a pillar, a B-Pillar or a C-Pillar having the profile, and to a vehicle provided thereof.
