Abstract

PURPOSE:To check any effect to the side of a cabin due to movements of an engine to the rear in every way, by installing such a means that displaces a body side mounting part of a suspension arm outward in the car width direction at a head-on collision. CONSTITUTION:Arm mounting parts 13, 14 being solidly formed with a front body 10 and extending ahead in the longitudinal direction of a car body are installed in each of symmetrical rear parts of the front body 10, and as for an engine mount member 20, a Y-shaped bottom part 21 is clamped to a cross- member 19, and both ends 24, 25 of two arm parts 22, 23 being situated in a Y-shaped upper part are clamped to these arm mounting parts 13, 14. Impact energy at a head-on collision is transmitted to the arm mounting parts 13, 14 so as to face outward aslant via these two arm parts 22, 23 of the engine mount member 20, so that these arm mounting parts 13, 14 are displaced outward, and thereby even if an engine E is moved to the rear, it is no longer hit on these arm mounting parts 13, 14, thus any possible effect to the side of a cabin 12 becomes lessened.
