Abstract

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.

First claim

The invention claimed is:

1. A carbody of a railcar,
the carbody comprising:
a roof bodyshell;
a supporting rod provided under the roof bodyshell, the supporting rod having an axis extending in a vertical direction and 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 rod and rotates relative to the supporting rod about an axis extending in the vertical direction to be displaced relative to the supporting rod in the vertical direction; and
a support target member supported by the roof bodyshell through the supporting rod 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 rod,
an upper external thread portion being formed at an upper end portion of the supporting rod,
a lower external thread portion being formed at a lower end portion of the supporting rod,
the upper end portion of the supporting rod being threadedly engaged with the roof bodyshell,
the rotating body being threadedly engaged with the lower end portion of the supporting rod to be rotatable relative to the lower end portion of the supporting rod about the axis; and
the support target member being connected to a region of a lower surface of the rotating body, the region being located around the axis.

2. The carbody according to claim 1 , wherein:
an attachment hole having an axis extending in the vertical direction is formed at the rotating body;
an adjustment hole is formed at the support target member, the adjustment hole communicating with the attachment hole and being larger than the attachment hole; and
the support target member is fastened to the rotating body by attaching a fastening member to the attachment hole through the adjustment hole.

3. The carbody according to claim 1 , wherein:
a plurality of attachment holes are formed at the rotating body, the attachment holes being arranged on a virtual circle around the axis of the supporting rod.

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