PROBLEM TO BE SOLVED: To provide a suspension device capable of preventing a ball joint from being detached from a knuckle even when a nut to fix the ball joint to support an outer end in the vehicle width direction of a lower arm to the knuckle is loosened. SOLUTION: A ball joint 21 to support a lower arm 12 has a head part 22a connected to the lower arm 12 in a space 20 between a knuckle body 14 and a lower arm supporting bracket 15, a shaft part 22b to penetrate a mounting hole 15f in the lower arm supporting bracket 15, and a male screw part 22c to be tightened by a nut 23. The distance d1 between a lower side of the knuckle body 14 facing the space 20 and an upper side of the lower arm 12 is set to be smaller than the distance d2 between a lower end of the male screw part 22c and an upper end of the mounting hole 15f of the lower arm supporting bracket 15, and even when the nut 23 is loosened and detached from the male screw part 22c, detachment of the ball joint 21 from the lower arm supporting bracket 15 can be prevented.
