摘要： A coupler system includes: a coupler main body attached to a longitudinal direction end of a carbody of a railcar so as to be rotatable in a yaw direction; a curvature information acquiring portion configured to acquire curvature information of a track, the railcar being located on the track; a control portion configured to determine a target rotation angle of the coupler main body in accordance with the acquired curvature information and output a rotation signal regarding the determined target rotation angle; and a rotation angle changing portion configured to rotate the coupler main body to the target rotation angle based on the output rotation signal. When the railcar is stopped or when the railcar is traveling at a coupling speed, the control portion outputs the rotation signal to start rotating the coupler main body.

摘要： A carbody of a railcar includes: a roof bodyshell; a supporting body provided under the roof bodyshell, the supporting body being attached to the roof bodyshell in a state of being positioned in the vertical direction; a rotating body which is threadedly engaged with the supporting body and rotates relative to the supporting body about an axis extending in a vertical direction to be displaced relative to the supporting body in the vertical direction; and a support target member supported by the roof bodyshell through the supporting body and the rotating body, the support target member being attached to the rotating body in a state of being positioned in the vertical direction, a vertical distance between the roof bodyshell and the support target member being adjustable by displacement of the rotating body relative to the supporting body.
