Abstract
The present invention relates to a spring-constant variable type stabilizer device for a vehicle, the device comprising a stabilizer provided between left and right wheels of the vehicle and a control cylinder arranged between the stabilizer and a lower arm, wherein spring constant of the stabilizer is variably adjusted by controlling the control cylinder. An oil port of an oil passage in communication with a reservoir chamber in a position assuming a neutral position of a piston stroke region is formed in a cylinder body of the control cylinder, a piston within the cylinder body is always biased from both directions thereof by means of a pair of springs, and a locked state of the control cylinder is promptly attained always in a complete neutral position.
