こととなる。[Operation and effect] The suspension member is attached to the vehicle body through the connecting means. When a vehicle collides and a front-back load larger than the normal load is applied to the suspension member, the suspension member moves rearward. As a result, the fixing of the fixing tool is released, and the first member and the second member are separated, but one of the first member and the second member is attached to the vehicle body,
Since the other is attached to the suspension member, the suspension member is eventually separated from the vehicle body.

The front suspension arm is an integral form having a substantially L-shaped or A-shaped planar shape, and has a large rigidity. On the other hand, the front suspension member has a large rigidity to withstand a normal load such as a load from a front suspension arm, a load from a steering gear box, a load from an engine mount, and a jack-up load for lifting a vehicle body. This suspension member having a large rigidity can be formed, for example, by casting two plate members so as to be hollow so as to be hollow, or by a cast aluminum product. As described above, the connecting portion between the front suspension arm and the front suspension member, both of which have great rigidity, may deform the dash panel or the floor during a collision and narrow the cabin space.

Thus, the connecting means is formed so that the deformation of the dash panel and the floor can be minimized. That is, in a preferred mode, the connecting means has a protrusion extending in the front-rear direction of the vehicle body,
A first member attached to the front suspension member, a second member having a hole into which the protrusion is fitted and attached to the vehicle body, and a fixture for fixing the first member and the second member are provided. Both the first member and the second member can be made by machining or casting. In the state of being fixed by the fixture, the protrusion of the first member and the hole of the second member are closely fitted to each other to make surface contact, and the surface contact and the fixture receive a normal load. When a load in the front-rear direction that is larger than the normal load is applied, the bolts that are fixtures break,
The front suspension member is separated from the vehicle body.

の方向の通常荷重を受け止めている。In the embodiment shown in FIG. 8, the suspension member 12 is for a front suspension, and the suspension member 12 has a load f 1 directed obliquely rearward from the front suspension arm 10 and a gear box for steering. Normal loads such as a lateral load f 2 , an obliquely upward load f 3 from the engine mount, and an upward jack-up load f 4 for lifting the vehicle body work. On the other hand, at the time of a collision, the collision load F in the front-rear direction of the vehicle body acts on the suspension member 12 substantially. The collision load F is, so to speak, a load in the front-rear direction, is larger than the normal load, and has a different working direction. Therefore, it is possible to fix the first member 32 and the second member 34 inseparably under the normal load applied to the suspension member 12 and separable under the longitudinal load applied to the suspension member 12. In the embodiment shown in 1,
The bolt 36 is fixing it. Bolt 36
Is broken by the collision load F. Then, the protrusion 33 of the first member 32 and the hole 35 of the second member 34 are fitted tightly together to prevent rattling due to a normal load and to receive a normal load in various directions.
