ンＡの案内溝５を形設する。In the drawings, reference numeral 1 indicates a guide plate according to the present invention. The guide plate 1 is composed of a punching frame 2 having a hollow shape and two pressed steel plates 3 and 4. The punching frame 2 is sandwiched, and both steel plates 3 and 4 are integrally joined in a palm shape,
The peripheral edges of both steel plates 3 and 4 are projected in parallel from the side surface of the punching frame 2 to form the guide groove 5 of the saw chain A having the outer surface of the punching frame 2 as the bottom surface.

の案内板と同じものである。In the figure, reference numeral 8 denotes a sprocket arranged at the tip of the guide plate 1, and the sprocket co-rotates with the sliding motion of the saw chain A to wear 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 mitigation. Reference numeral 9 is 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 the chain saw body (not shown). Near the mounting hole 9, the punching frame 2 and the two steel plates 3 and 4 are both formed into a flat plate shape,
The punching frame 2 and both steel plates 3 and 4 are joined by spot welding or the like. The structure of these guide plates is the same as that of conventionally known guide plates.
