Stabilizer control apparatus

A stabilizer control apparatus, comprising:

• 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 switching over the spring member from an extendable/retractable position to a neutral position and vice versa,
• the cylinder member being supported by one of the vehicle body and one of the first and second supporting members,
• the piston member being supported by the other of the vehicle body and one of the first and second supporting members and slidably inserted into the cylinder member,
• the spring member being accommodated in the piston member, which is inserted into the cylinder, and axially spanned between the piston member and the cylinder member,
• the engaging/disengaging mechanism allowing the piston member to axially move relative to the cylinder member when the spring member is in the extendable/retractable position and preventing the piston member from axially moving relative to the cylinder member when the spring member is retained in the neutral position.
