PURPOSE: To provide a two-axle vehicle suspension device having a function of clearing a high road level as well as a high braking function.

CONSTITUTION: An intermediate section is supported on a frame between a leaf spring 21 for a front axle suspension and a leaf spring 23 for a rear axle suspension in such a state as capable of free turn in a longitudinal direction. Also, a link member 30 with both ends rotatably connected to adjacent spring ends is laid, thereby providing a structure for reversing a vertical motion from one of the springs 21 and 23 for transmission to the other. At the same time, the turning support point of the member 30 is positioned at the preset upward distance from a connection with the rear leaf spring 23 for generating moment against the moving direction of the member 30. As a result, a rear axle 24 is made to share an axial load acting on a front axle 22 at the time of clearing a road level and at the time of a braking operation, axial load distribution on the two axles is kept similar to the case of a normal travel condition.
