Patent ID: 7287759

Claim:
A stabilizer device comprising a stabilizer constituted by a shaft portion mounted on a vehicle body side and arm portions which are attached to left and right vehicle wheel sides by bending each side of the shaft portion; and an actuator which divides the stabilizer into two at the shaft portion and produces a rotary angle difference between the shaft portions thus divided, wherein the actuator comprises: a cylinder connected to one of the shaft portions; a piston provided within the cylinder so as to be capable of movement in an axial direction, the piston dividing the interior of the cylinder into two chambers to and from which a pressure fluid is supplied and discharged; a piston rod having one end connected to the piston and another end extending outward from the cylinder to be connected to the other shaft portion; a linear motion-rotary motion conversion mechanism which causes the piston and the piston rod to rotate relative to the cylinder when the piston moves in the axial direction; and an axial motion permitting mechanism which prohibits relative rotation but permits relative axial motion, wherein the piston rod and the other shaft portion are connected via the axial motion permitting mechanism.
