Abstract
A stabilizer control apparatus includes a stabilizer bar including both ends supported by right and left wheels of a vehicle, respectively, and an intermediate portion supported to a vehicle body by first and second supporting members, and a switching device arranged between one of the first and second supporting members and the vehicle body and including a cylinder member, a tubular piston member, a spring member, and an engaging/disengaging mechanism. The switching device switches over the spring member from an extendable/retractable position to a neutral position and vice versa. The engaging/disengaging mechanism allows the piston member to axially move relative to the cylinder member when the spring member is in the extendable/retractable position and prevents the piston member from axially moving relative to the cylinder member when the spring member is retained in the neutral position.
