Beschreibung
Zusammenfassung:	The problem addressed by the present invention is, in a vehicle-body inclination device, to perform rapid vehicle-body inclination control while thoroughly taking advantage of a conventional-technology automatic height-adjustment valve for leveling-adjustment control. The vehicle-body inclination device (30) is configured containing: a control unit (110); and individual inclination units (112, 113) that are provided corresponding to air springs (22, 23). The individual inclination unit (112) is able to perform sufficient supply/discharge of air to/from the air spring (22) by driving a high-volume valve (170) and a control valve (40) using a height deviation, which is the deviation between the height command value provided by the control unit (110) and the vehicle height value obtained from a link-lever mechanism (24). The control valve (40) has a double-layer structure of a spool (80), a control sleeve (90), and an affixed sleeve (91). The control sleeve (90) is driven to move by the link-lever mechanism (24) and a rotary-linear conversion mechanism (44). The spool (80) is driven to move by a spool actuator (120) in accordance with a set vehicle height value.
