The taper part 7 of the side surface inclined in the direction is a rail shape.

In this reference example, as shown in FIG. 2, the width of the upper flange portion 2A of the joint plate 2 fixed to the rail 1 by the joint plate bolt 4 via the adhesive layer 3 is increased, and the joint plate abdomen 2B The cross-sectional shape is such that the width is narrow and the length of the joint plate bolt 4 is shortened so that the joint plate bolt 4 is protected from the collision of the wheel or carriage member from the outside. Here, the width of the flange 2A at the top of the joint plate 2 is wide, the width of the joint plate abdomen 2B is narrow, and the length of the joint plate bolt 4 is shortened, but instead, Simply widen the width of the collar 2 </ b> A at the top of the joint plate 2. Alternatively, the seam plate abdomen 2B is partially shaved so that the short seam plate bolts are hidden in the flange 2A on the upper part of the seam plate 2, that is, the seam plate bolt is viewed from above by the upper part of the seam plate. Just hide it.

Further, in this reference example, as shown in FIG. 1, since the tapered portion 6 of the side surface inclined so as to gradually spread in the line direction is formed at the joint plate end portion 5, when the wheel is derailed, Even if the member of the carriage collides with the joint plate end portion 5, the impact on the joint plate 2 can be reduced. When the tip of the seam plate is perpendicular to the track direction as in the past, if the wheel is derailed, the wheel or carriage member will collide with the end of the seam plate. Is large, leading to breakage of the joint plate bolt.
