A spike main body 11 is formed by punching a high-carbon steel plate material capable of resistance welding and bending it into an L-shape, and is provided with a mounting hole 13. The mounting seat plate 12 includes a protruding piece 14 that rises substantially at right angles to the mounting seat plate 12, and a reinforcing rib 15 is provided at a bent portion between the mounting seat plate 12 and the protruding piece 14. A notch 16 is provided at the center of the tip 14 a of the protruding piece 14. The notch 16 is provided for ensuring good and reliable welding of the cemented carbide tip 20 described later.

能である。As shown in FIG. 2, the cemented carbide tip 20 has a rectangular parallelepiped shape having a thickness slightly larger than that of the protruding piece 14, and has a joint portion 21 formed in a wedge shape.
2 and the end face 17 of the protruding piece 14 as shown in FIGS.
5 and 6, the wedge-shaped joint 21 is joined to the protruding piece 14 so as to be sandwiched from both sides by the molten meat 18 at the tip of the protruding piece 14, as shown in FIGS. When the tip 20 is resistance-welded to the tip 14a of the protruding piece 14 as described above, if the straightness of the ridge 22 of the wedge-shaped joint 21 is high, the entire length of the ridge 22 contacts the end face 17 of the protruding piece 14. Since it is difficult to obtain complete straightness on the ridge 22, when the ridge 22 is pressed against the end face 17 where the notch 16 is not provided on the tip 14 a of the projection 14, only one side of the ridge 22 is pressed. However, there is a possibility that poor welding may occur due to only contact with the end face 17. However, if the notch 16 is provided at the center of the tip 14a of the protruding piece 14 as described above, the ridge 22 will surely contact the end faces 17 on both sides of the notch 16, And the chip 20 is firmly and reliably joined so that the tip 20 is sandwiched by the molten meat 18 at the tip 14a of the protruding piece 14. Note that the notch 16 is used for the chip 2
The same effect as described above can be obtained even if it is provided at the central portion of the wedge-shaped joint 21 of zero. The tip 20 is preferably made of a cemented carbide, but may be made of another wear-resistant metal material.

必要がない。As described above, according to the spike of the present invention, the ridge of the wedge-shaped joint of the wear-resistant metal tip is resistance-welded to the tip of the spike protruding piece, and the wedge-shaped joint is formed by the protrusion. Since it is joined to the protruding piece so as to be sandwiched from both sides by the melted piece of the piece, it not only has excellent wear resistance, but also has a high joining strength, particularly acting on the tip of the protruding piece. It has large proof stress against bending stress. Therefore, there is no need to replace spikes over a long period of time.
