の案内板と同じものである。In the drawing, reference numeral 8 denotes a sprocket disposed at the tip of the guide plate 1 and co-rotates with the sliding of the saw chain A to reduce wear of the sliding contact portion between the saw chain A and the guide plate 1 at the tip of the guide plate 1. It is for reducing. Reference numeral 9 denotes a mounting hole provided at the base of the guide plate 1, and the length of the saw chain A can be adjusted by mounting the guide plate 1 on a chain saw body (not shown). In the vicinity of the mounting hole 9, the punching frame 2 and the two steel plates 3 and 4 are both formed in a flat plate shape.
The punching frame 2 and both steel plates 3 and 4 are joined by spot welding or the like. The configuration of these guide plates is the same as a conventionally known guide plate.

耐用寿命を延長できる。(2) A punching frame having an outer surface as a bottom surface is in the guide groove to reinforce the guide grooves on both sides of the guide plate, and each steel plate is expanded outward at a steel plate joint formed inside the punching frame. Since it is reinforced by forming a plurality of reinforcing ribs elongated in the longitudinal direction in the shape of a protrusion, the rigidity as a guide plate is high,
Also, since the wall thickness of the guide groove can be set to the required thickness,
The service life can be extended.
