[Scope of utility model registration request]

The piston inserted into the cylinder communicates with the first and second chambers in the cylinder partitioned by the piston (an orifice passage formed in the piston,
a piston rod connected to the piston and extending upward; a drive pin extending in the longitudinal direction of the piston rod within the piston rod and slidable relative to the piston rod; a control valve body that is attached to the lower end and can change the effective flow area of the orifice passage; and a first control valve body that drives the control valve body via the drive pin.
In a vehicle suspension incorporating a damping force switching type shock absorber consisting of an actuator, a main air spring chamber is provided in an upper part of the shock absorber and coaxially arranged with the piston rod, and the main air spring A sub-air spring chamber is provided coaxially with the piston rod immediately above the chamber, and a compressed air generator that supplies air at a required pressure to the main air spring chamber and the sub-air spring chamber. A vehicle that detects the vehicle height of the vehicle, which is equipped with a spring constant/switching on-off valve that communicates and cuts off the chamber and the auxiliary air spring chamber, and a second actuator that drives the spring constant switching on-off valve. high sensor and
A vehicle body posture sensor that detects changes in the vehicle body posture is provided, and controls the compressed air generator to maintain the vehicle height of the vehicle at a predetermined height in response to a detection signal from the vehicle height sensor. a first control means for supplying a signal; and a first control means for increasing or decreasing at least one of the damping force of the shock absorber and the spring constant of the air spring chamber in accordance with the detection signal from the vehicle body attitude sensor. and the second
a second control means for supplying a control signal to the actuator of the vehicle suspension device.
