較的短いもので足りることとなる。As mentioned above, in particular, the trailing arm (1) is formed with an extension part (5) that protrudes forward from the pivot point (E) on the vehicle body side,
Since the first lateral link (21) is connected to this front extension part (5), the first lateral link (21) is connected to the pivot point (E) of the arm (1) compared to the case where it is connected to the intermediate part of the arm (1). Therefore, the link length need only be relatively short as in the embodiment.

By connecting the first lateral link (21) further forward, the span between the third lateral link (41) at the rear and the first lateral link (21) can be made larger than before, so that the wheels (18) The toe rigidity against the side force acting on the grounding point of the tire (17) can be maintained sufficiently higher than before.

。Furthermore, since the vehicle body side pivot points (F) and (H) of the first and third lateral links (21) and (41) are placed before and after the fuel tank (81), one-car docking point (F), (H) It is possible to take a large span between the two, thereby maintaining even higher toe rigidity. (Effects of the Invention) As described above, according to the present invention, the front end side is pivoted to the vehicle body, and the rear A trailing arm that rotatably supports the wheels at its end and is placed longitudinally along the side wall of the fuel tank located under the rear floor of the vehicle, and is connected to the vehicle body at one end and the trailing arm at the other end. In a vehicle rear suspension consisting of a plurality of lateral links arranged in the lateral direction of the vehicle body, the front one of the plurality of lateral links is
This connection point on the vehicle body side is placed forward of the fuel tank, and the rear connection point on the vehicle body side is placed behind the fuel tank, preventing interference between the front and rear lateral links and the fuel tank. It is possible to obtain sufficient link length while also securing tank capacity, and to keep changes in wheel alignment to a minimum.Furthermore, the span between the front and rear lateral links' respective body-side connections can be increased. It is possible to maintain high toe rigidity.
