It has a structure in which outer panels are stacked. Grooves are formed along the longitudinal direction of the intermediate plate. A lid member having a U-shaped cross section is inserted from the outside of the groove, and a lubricant passage for flowing a lubricant is formed between the groove and the lid member. Further, as described above, grooves are formed along the longitudinal direction on the inner surface sides of the left and right outer plates instead of the middle plate.
In some cases, a lubricant passage is formed by inserting a lid member having a U-shaped cross section from the outside of the groove.

A fitting step is formed on the outer periphery of the groove, and a lid member is attached to the fitting step by an adhesive, brazing, or welding so as to be flush with the side surface of the guide plate. The lid member closes the opening of the groove to form a lubricant passage between the groove and the lid member.

Along with this, the peripheral edge of the thin plate which is the lid member is tapered to this tapered portion so as to match the tapered portion, and is fastened and fixed to the guide plate with bolts or nuts.

Regarding No. 79508, the thickness of the middle plate of the guide plate is 1.
35 mm to 1.70 mm, while the outer plate has a thickness of 1.20
It is from mm to 1.70 mm, and both plates are thin plates. Even if the lubricant passage is provided within this thickness, it is actually very difficult to process, and the lubricant passage is shallow and easily clogged.
It has not been put to practical use at all. Further, when the lubricant passage is blocked, there is no method for cleaning or repairing the lubricant passage, and there is no choice but to discard the lubricant passage.

Since the lid member is a thin plate having a narrow width, lateral bending and twisting are likely to occur during the production of the lid member, resulting in poor productivity.
Further, since the lid member is a thin plate, it is difficult to attach the lid member to the guide plate, and as described above, the method of fitting the lid member into the fitting step portion causes the timber to be immediately peeled off during cutting work such as wood. There was a problem. That is, in the attachment method using an adhesive, when the entire guide plate is sandwiched by wood or the like and bent, the lid member is also bent, so that there is a problem that it is immediately peeled off. Further, in the mounting method by brazing or welding, there is a problem that the guide plate that has been hardened to improve rigidity is softened and the quality of the guide plate deteriorates.

Further, the quenching of the guide plate causes deformation and distortion, but it is very difficult to correct the distortion of the processed product having the above-mentioned shape. When the distortion remains, it is difficult to fasten the wide thin plate to the guide plate body without oil leakage, because the partial unevenness easily forms a gap.

A locking groove 15a is formed on the same side as the side where it is provided. When the first nesting member 21 and the second nesting member 31 are inserted from both side surfaces of the guide plate 4 in the through hole 10 and face each other and are fitted, the locking projection 1 of the first nesting member 21 is inserted.
4a is engaged with the engaging groove 15a of the second insert member 31, and the engaging groove 15a and the engaging protrusion 14a are also engaged in the remaining engaging portions 14, 15. Locking surface 1
6 abuts on the locking surface 12 of the guide plate 4 to prevent the closing portion 13 from entering the through hole 10 and completely closes the through hole 10. In other words, the first insert member 21 and the second insert member 31 are locked to the guide plate 4 by sandwiching the locking surface 12 which is a part of the guide plate 4. Then, by assembling the first insert member 21 and the second insert member 31, both members 2
A hollow portion 24 to which a lubricant is supplied is formed between 1 and 31.

A U-shaped member 23 as a channel-shaped lid member made of synthetic resin is removably tightly fitted in the groove portion 22 along its longitudinal direction by its elastic force. By assembling the U-shaped member 23 in the groove 22 as described above, the lubricant passage 18 for flowing the lubricant is formed. Further, as shown in FIG. 1, the supply pipe 19 is attached to the first insert member 21 closest to the base end of the guide plate 4, and the hose 20 extending from the lubricant supply source (not shown) is attached to the supply pipe 19. You can cut hard wood or stone while connecting and supplying lubricant.

And through the supply pipe 19 to the hollow portion 24 at the base end of the guide plate 4. Then, the lubricant is supplied to each lubricant passage 18
It is supplied to the hollow portion 24 at the tip end portion of the guide plate 4 via and is discharged from each discharge hole 17. The discharged lubricant with significantly alleviate the guide plate 4 a frictional resistance between the object to be cut to flow on both sides of the guide plate 4, reaches the saw chain 5 to slide the guide plate 4 bottom surface therewith guide plate 4 and the Increase lubricity.

When wood sawdust or the like enters the inside of 8 and becomes clogged, the U-shaped member 23 and the second nesting member 31 are disengaged first, and then the U-shaped member 23 at the clogged part is removed. It is removed from the groove 22 against the elastic force. Then, the sawdust and the like clogged in the groove portion 22 is removed by a brush or the like (not shown), and after the removal, the U-shaped member 23 and the first nesting member 21 are in the reverse order of the above description. Attach to 31.
