Abstract: A vehicle structure includes: a pair of side frames disposed apart in a vehicle width direction and extending in a vehicle front-rear direction; and a cross member extending in the vehicle width direction, and penetrating the pair of side frames and connecting the pair of side frames. The cross member is formed of a pipe having a substantially square cross section with a corner portion curved in an arc shape. A corner portion of the cross member at a vehicle lower side is set to have a curvature radius larger than a curvature radius of a corner portion at a vehicle upper side.

Abstract: An electrical connection box has electronic components mounted therein and includes a heat pipe for radiating heat generated from the electronic components to the outside. The heat pipe has a heat absorbing portion inside the connection box and a heat radiating portion outside the connection box. The heat pipe is formed of an electrically conductive material, and an electrically conductive heat collecting member is provided for collecting the heat generated from the electronic components. The heat absorbing portion of the heat pipe is connected to the heat collecting member, and a grounding current is supplied to the heat pipe and the heat collecting member.
