摘要： A sub frame structure of a vehicle comprises a pair of right-and-left side members and a front cross member interconnecting the side members in a vehicle width direction. The side member includes a front support bracket and a rear member holding member which are arranged along the vehicle longitudinal direction and to which a front connection portion and a rear connection portion of the upper-side lower arm are pivotally connected, and comprises a front part positioned in front of the front support bracket. Herein, the front part of the side member is rigidly connected to a floor frame of a vehicle body at its front end and configured in a long shape such that the front part extends obliquely forward and outward, in the vehicle width direction, from a position where the front support bracket is provided.

摘要： Coolant flowing from a compressor passes through a heat exchanger and opening-degree adjustable type of expansion valves for heating, and an external heat exchanger. The coolant passing through the external heat exchanger is capable of passing through an expansion valve and a heat exchanger for cooling, and an expansion valve and a heat exchanger for cooling a battery. A grille shutter to change an introduction state of traveling air is provided in front of the external heat exchanger. When pressure of the coolant (particularly, pressure of the coolant at a timing after the coolant passes through the external heat exchanger) is a specified pressure or lower, the grille shutter is closed, whereby the heat-exchange performance of the external heat exchanger is lowered.

摘要： A rear subframe structure is provided with a rear subframe configured such that a front cross member, a rear cross member, a pair of left and right upper side members extending in a vehicle front-rear direction, and a pair of left and right lower side members extending in the vehicle front-rear direction are connected; and a vehicle-body mounting portion formed on each of both ends of the front cross member in the vehicle width direction, and on each of rear ends of the upper side members. The rear subframe further includes a lower-arm support portion formed on a lower lateral portion of the rear cross member, and a stabilizer support member for supporting a stabilizer. The rear cross member connects the upper side members and the lower side members in an up-down direction. The rear cross member includes an upper-surface rear-side projection portion projecting rearwardly. The stabilizer support member is mounted between the lower-arm support portion and the upper-surface rear-side projection portion of the rear cross member.
