Claim:
A vehicle body front structure including a front bulkhead having a an upper beam and a lower beam, and a cooling system component having a top part provided to the upper beam and a bottom part provided to the lower beam, said vehicle body front structure comprising: a top support mechanism, provided to the upper beam, for supporting the top part of the cooling system component in such a manner as to be movable rearwardly of a vehicle body; and a bottom support mechanism, provided to the lower beam, for supporting the bottom part of the cooling system component in such a manner as to be movable rearwardly of the vehicle body; wherein the top support mechanism comprises: an upper support bracket provided to the upper beam; an upper movement bracket provided to the top part of the cooling system component and having slits formed in a region thereof corresponding to the upper support bracket and opening forwardly of the vehicle body; and top fastening means having top fastening members passed through the slits in order to fasten the upper movement bracket to the upper support bracket; wherein the top fastening means includes a top resilient member located between the upper movement bracket and the top fastening members; wherein the bottom support mechanism comprises: a lower support bracket provided to the lower beam; a lower movement bracket provided to the bottom part of the cooling system component and having a slot formed in a region thereof corresponding to the lower support bracket and extending in a forward-backward direction of the vehicle body; and bottom fastening means having a bottom fastening bolt passed through the slot in order to fasten the lower movement bracket to the lower support bracket; wherein the bottom fastening means has a bottom resilient member positioned between the lower support bracket and the bottom fastening bolt; wherein the upper movement bracket and the upper support bracket are mountable to the top part of the cooling system component and the upper beam, respectively, with the upper movement bracket and the upper support bracket being fastened together by the top fastening means; wherein the lower movement bracket and the lower support bracket are mountable to the bottom part of the cooling system component and the lower beam, respectively, with the lower movement bracket and the lower support bracket being fastened together by the bottom fastener means, and wherein when the upper and lower movement brackets are subjected to an impact load acting from a front of the vehicle body, the slits formed in the upper movement bracket and the slot formed in the lower movement bracket allow the upper and lower movement brackets to move rearwardly of the vehicle body such that the rearward movement of the upper movement bracket causes the top fastening members to be removed from the slits in the upper movement bracket and the rearward movement of the lower movement bracket causes the bottom fastening bolt to remain passed through the slot in the lower movement bracket.
