Abstract
A carriage-body inclination device () has individual inclination units () that are provided corresponding to air springs (), and a control unit (). The individual inclination unit () can sufficiently execute supply or release of air to or from the air spring () by driving a control valve () and a large-capacity valve () using a height difference value which is a difference between a height instruction value provided by the control unit () and a height value obtained from a link-lever mechanism (). The control valve () has a two-layer structure of a fixed sleeve (), a control sleeve (), and a spool (). The control sleeve () is moved and driven by the link-lever mechanism () and a rotation-translation conversion mechanism (). The spool () is moved and driven by a spool actuator () according to a set height value.
