比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 (5), the pivot point (E) of the connection (1) is close to the middle part of the arm (1), so the length of the link is the same as in the example. A relatively short length will suffice.
またトレーリングアーム(1)の車体側枢着点(E)の
下方にはリンクが存在しないので、最低地上高を稼ぐこ
とができる。Further, since there is no link below the pivot point (E) on the vehicle body side of the trailing arm (1), the minimum ground clearance can be increased.

とができる。In the above, since the first lateral link (two pivot points (F) on the vehicle body side) is placed in front of the fuel tank (81), sufficient link length can be achieved while preventing interference with the fuel tank (91). The first lateral link (21) can be employed, and the capacity of the tank (81) can also be secured.

This makes it possible to minimize wheel alignment changes.

In a rear suspension for a vehicle, the plurality of lateral links are composed of a trailing arm arranged in the longitudinal direction of the vehicle body, and a plurality of lateral links connected to the vehicle body at one end and the trailing arm at the other end and arranged in the lateral direction of the vehicle body. Since the connection point on the vehicle body side of one of the links is placed in front of the fuel tank, sufficient link length can be obtained while preventing interference between the one lateral link and the fuel tank. Not only can capacity be secured, but changes in wheel alignment can also be kept to a minimum.
