例では横断面が凸形状である無端の鋸（２）の鋸身（２

状としている。A plate-shaped base (6) with the plate surface facing up and down is placed on the left side of the endless saw (2) in the cutting action line area, and a plate-shaped base (6) with the plate surface facing up and down is placed between the plate-shaped base (6) and the frame body (1). Lifting guide mechanism (7)
After the lower surface of the plate-shaped base (6) is in contact with the upper surface of the material to be cut and the machine body is placed on the material to be cut, the cutting operation begins, that is, the handle part (IC) is manually moved downward. A frame body (1) by pressing, an endless saw (2) arranged or attached to the outside of the frame body (1), a suspension wheel (3), an electric motor (4 pieces) and a guide plate (10 pieces). The structure is configured to guide the lowering of the movable part consisting of other parts, etc., and the raising of the movable part to return to the original position after the cutting operation is completed, and as shown in Fig. 3.4, this is carried out. In the example, the saw blade (2) of an endless saw (2) with a convex cross section is shown.
Corresponding to b), the lower end of the guide plate (1) has a concave cross section.
上記のように鋸機は構成され、その構成要素の一つであ

の切断作用時の上方への逃げ、左・右横方向への振れを
制止することになるがこの切断作用時の逃げ振れとは別
個に、無端の鋸（２）自身による振れが存在する。The saw machine is constructed as described above, and one of its components, the guide plate (10), is connected to the endless saw (2) in the cutting action area.
This prevents upward escape and left/right lateral deflection during cutting, but apart from this escape deflection during cutting, there is also deflection due to the endless saw (2) itself.
当然無端の鋸（２）には緊張機構（９）により強く緊張
が与えられている。Naturally, the endless saw (2) is strongly tensioned by the tensioning mechanism (9).
しかし なおその振れは存在しつづけるものであり こ

（３）上での曲線走行と、懸架ホイール（３）間での直
線走行の反復運動に対応するために設定された無端の鋸
（２）の細さにその大部分を由来する。However, the vibration continues to exist, and this is due to the repetition of the endless saw (2) running in curves on the suspended wheels (3) and running in straight lines between the suspended wheels (3) as it rotates. Most of this comes from the slenderness of the endless saw (2), which is set to accommodate the movement.
本発明はこの振れを解消することを目的の一つとしてい
る。One of the objects of the present invention is to eliminate this vibration.
この無端の鋸（２）自身による振れの幅は、切断作用線
域にあっては、前、後脚柱部（１ａ）、（１ｂ） ＩＣ
接する前後端ではゼロでアシ、真央で最大となる。The width of the swing caused by this endless saw (2) itself is the same as that of the front and rear pillars (1a) and (1b) in the cutting action line area.
At the front and rear ends where they touch, it is zero at the reed, and at the center it is maximum.

その下端部の前後方向の形状が前、後端から真央部方向

真央と曲線状の形状の頂点とが一致する。FIG. 5 is a side view showing that the lower end of the guide plate (10) has been expanded downward by an amount corresponding to the width of the swing of the endless saw (2) in the cutting action line area, with the plate thickness unchanged. ,
The shape of the lower end in the front-rear direction is a curved shape that swells downward from the front and rear ends toward the center, and the center of the cutting action line area coincides with the apex of the curved shape.

面と案内板（１０）の凹形状ないし凸形状に形成された
下端面との接触の度合を切断作用線域の全斌にわたって
均一に計ることができる。In this way, if the shape of the lower end of the guide plate (10) in the front-rear direction is made into a shape (curved) corresponding to the runout of the endless saw (2), it is possible to absorb and eliminate the runout of the endless saw (2). However, at the same time, the degree of contact between the back surface of the saw blade (2b) of the endless saw (2) and the concave or convex lower end surface of the guide plate (10) should be adjusted over the entire cutting action area. It can be measured evenly across the entire length.

異ってくる。However, this downwardly swollen curved shape with the center and apex of the cutting action line area coincident with the cutting action line area shows the case of no load state where no cutting action is performed, and it does not reflect the actual cutting action. The situation is different when cutting resistance is applied.

る。Applying this to the embodiment shown in Fig. 1.2, the rotation of the drive suspension wheel (3) placed on the upper part of the rear leg column (1b) is counterclockwise, and the endless rotation in the cutting action line area is Assuming that the direction of travel of the saw (2) is from the front leg column (1a) to the rear leg column (1b), the cutting operation actually starts and cutting resistance is applied to the endless saw (2). In this case, a strong tensile force is received at a position closer to the rear pillar part (1b) in the cutting action line, and the cutting resistance and the suspension wheel are (3)
It receives compressive force from both directions due to the rotational force from the opposite direction.

部分的な緊張の“ゆる札あるいは１曲がシ□を生じる。Therefore, in this embodiment, the endless saw (2) in the cutting action line area has a partial saw at a position closer to the front pillar (1a), that is, at a position upstream in the running direction from the position where the cutting action is applied. A tense ``loose note'' or one song causes a shi□.

To solve this problem, add 1. slack 2. Alternatively, one song may overlap shapes corresponding to the number 9, but in this case, the apex of this overlapped shape is, in terms of the greatest common divisor, the running direction of the endless saw (2) at the front pillar ( 1
If the direction is from a) to the rear leg column (1b), the rear leg will move to a position closer to the front leg column (1a) than the center of the cutting action line area, and if the running direction is the opposite direction, the rear leg Pillar part (1b
) will be moved to a position close to

あるいは無端の鋸（２）の切断（ｉ’１１１）能力等、
種々の要因が関係する。The exact shape corresponding to this 'looseness' or '9 bend' is determined by the rigidity of the thin end of the endless saw (2), the suspension wheel (3) rotational force and rotational speed;
Or the cutting (i'111) ability of the endless saw (2), etc.
Various factors are involved.
ゆえに、下方に除々に脹らんだ形状の頂点を単なる一点

に直線状部分を取入れた形状とも充分になりうる。Therefore, instead of making the apex of a shape that gradually swells downward as just a single point, it may be sufficient to have a shape that partially incorporates a straight portion, such as having a flat straight top portion.

わけだが無端の鋸（２）との嵌合の形態を必ずしも切断
作用線域の全線域でとる必要はない。As mentioned above, the guide plate (10) is fitted with the saw blade of the endless saw (2) at its lower end, and the shape of the lower end in the front-rear direction is centered between the front and rear ends. The endless saw (2) absorbs its own runout and "looseness 5." or "1 bending" by creating a curved shape that gradually swells downward in the direction of the cutting edge, or a shape that also includes some linear parts. However, it is not necessary to form a fit with the endless saw (2) over the entire cutting action line area.

なる。As mentioned above, the endless saw (2) itself has rigidity even though it is thin, so if it is fitted at intervals that match its rigidity and the unnecessary parts in between are cut off. Naturally, the shape of the lower end in the front-rear direction becomes a continuous waveform.

先で切りひらくことにより軽減する。Figure 6 is a side view showing that the lower end of the guide plate (10) has a curved shape that gradually swells downward from the front and rear ends in the front-rear direction, forming a continuous waveform. As a result of the continuous waveform shown in the figure, the bottom end surface of the guide plate (10), which is formed in the shape of a concave or convex contact, comes into contact with the back surface of the saw blade (2b) of the endless saw (2). The area is reduced by the amount corresponding to the corrugated space, and the space can also be used as a saw dust discharge area or a discharge hole. However, if this continuous waveform is shaped like a cutting edge or a saw blade, the synergistic effect with the saw teeth of the endless saw (2) will result in cutting C.
F! ! I) In addition to improving the performance, the burden of entering the guide plate (10) into the groove formed in the material to be cut is reduced by cutting with the cutting edge of the guide plate (10).

。(Effects of the Invention) Although the saw machine having the guide plate of the present invention as a component has a limited cutting width and cutting depth depending on the size of the frame body, it can be used for portable purposes as shown in Fig. 1.2, for example. As shown in the embodiment configured as shown in FIG. 2, the purpose is to perform the cutting operation with the machine body fixed at a fixed position, thereby obtaining precise dimensional cuts and smooth cut surfaces using the small saw blade of the endless saw.
したがりて案内板の切断作用線域にある無端の鋸の切断

忠実に実現することになる。Therefore, the shape of the lower end of the guide plate in the front-rear direction is designed to gradually swell downward from the front and rear ends toward the center of the guide plate.
．． Absorbing and resolving the problem, and maintaining the proper fit between the saw blade of the endless saw and the guide plate over the entire cutting action area allows the guide plate to accurately perform its intended role. This also prevents phenomena such as breakage and disengagement of the endless saw during cutting operations, thereby faithfully realizing the purpose of the saw.

。Furthermore, the depth of cut into the material to be cut at the start of cutting work is
By starting from the apex or apex portion and gradually moving to the front and rear ends, it is possible to avoid the temporary and excessive impact that would occur when the entire line area of the cutting action area is made straight, and to gradually move to the front and rear ends. This results in a smooth start of cutting work.
