发明名称 VEHICLE-BODY FRONT STRUCUTRE
摘要 A vehicle-body front structure includes a tower portion comprising a pole portion which extends substantially vertically and a tower top portion which is positioned at an upper portion of the pole portion and projects from the pole portion longitudinally along a front side frame, constituting attachment portions of an upper arm of a front-wheel suspension. A stabilizer-support pedestal for supporting a stabilizer is provided to be connected to the pole portion and the tower top portion. Thus, the pole portion of the sub frame can be properly reinforced by using the stabilizer-support pedestal, so that the rigidity of the upper portion of the pole portion can be properly increased.
