Abstract: A reinforcing plate is provided between an inner central portion that structures a portion of a connecting member and a rear end portion of a dash cross-member. The reinforcing plate is a wrought member and is joined (at a join portion) to both the inner central portion and a rear wall portion of the dash cross-member via joining members. Because the wrought member has high tensile strength, when the reinforcing plate is provided at the join portion of the connecting member, a tensile load acting on the join portion may be borne by the reinforcing plate, and breakage of the connecting member may be suppressed. Therefore, an impact load transmitted from a front side member through the connecting member may be transmitted to the dash cross-member and rockers.
