To reduce an occupied space.
In a vehicle suspension device 10, axle brackets 48L and 48R for rotatably supporting front wheels 16R and 16L of an automobile are vertically movably connected to a vehicle body 26 through lower arms (first arms) 50L and 50R and second arms 104L and 104R. For the second arms 104L and 104R, one of a pair of front and rear arm parts is configured by a leaf spring 72 to be bent and deformed accompanying the vertical movement of the front wheels 16R and 16L with respect to the vehicle body 26. The leaf spring 72 is also bent and deformed when the vehicle body 26 is rolled to generate force in a direction of suppressing the roll. That is, since a function as a part of the second arms 104L and 104R, a function as a spring and a function as a stabilizer are compacted in the leaf spring 72, the occupied space of a device can be reduced compared to the case of sharing the respective functions by respective independent components.
