PURPOSE: To make it possible to structure a guide plate so that the lubricant continuing function may be improved by scrap eliminating materials and manufacture a fill body matching to a groove size and lubricant bore by mounting the fill body in a guide groove of the edge side coupled with scraps eliminating materials on a saw chain to form a protruded portion of a groove bottom and further, lowering the end surface thereof with the lubricating bore portion. CONSTITUTION: A saw chain 3 is provided with a scrap eliminating material 4 mounted between side materials 5 and 6, and the bottom section 4A is coupled with a guide groove 8 of a guide plate 2. A fill body 10 is on a groove bottom 8A and the end surface 10A is protruded to the groove bottom, the center of which becomes like concave and a lubricating bore 9 is exposed thereon. The distance which the fill body 10 is extended to the elongated direction is several times the diameter of the lubricant bore so that the lubricant may be distributed to the chain pivotted section 7 before the scrap eliminating material 4 leaves the protruded portion 10A of the groove bottom 8A. A tool to form the fill body 10 in the guide groove 8 has a protruded section in the center of a narrow board to be inserted in the guide groove 8 and further, covers the lower region of the lubricating bore 9. |
