One end of a radius rod 19 is swingably connected via a pair of bushes 17 and 18. The radius rod 19 extends substantially horizontally, and the other end is swingably connected to the vehicle body 7. The toe of the rear wheel 1 is regulated by the pair of bushes 17, 18 and the radius rod 19 as described above. By doing so, even if sufficient longitudinal compliance is given to the rear wheels 1, it is possible to prevent toe changes that impair steering stability from being affected. In addition, in order to minimize toe changes due to the vertical stroke of the suspension, the axes 20 of the pair of bushes 17 and 18 are approximately parallel to the straight line 21 connecting the other end of the radius rod 19 and the inner end of the lower control arm 3. It is set as follows.
