動要因となっている。(Prior art) As shown in Fig. 6, a crawler type endless belt is constructed by hanging an endless belt 1 made of rubber or other elastic material around a drive wheel 2 and an idler wheel 3, each consisting of a sprocket or a drum wheel. 4, etc., and it is known to circulate by the engagement force or frictional interlocking of the engagement claws. At this time, lugs 5 are formed on the ground surface side of the endless band 1, and a core metal 6 is embedded, but there is a large difference in rigidity against vertical loads between the part where the core metal is embedded and the part where the core metal is not embedded. Therefore, the swing width is large and causes violent vibration.

分に取り除くことができなかった。 Therefore, in order to reduce the above-mentioned difference in rigidity and eliminate vibration factors, a lug pattern may be used that minimizes the area of the lug 5 within the projection area of the core bar 6 as shown in FIG. 7, or a lug pattern as shown in FIG. The thickness of the lug 5 has been changed as shown in FIG. 9, or the ground plane 5a of the lug 5 has been shifted from the projected area of the core bar 6 as shown in FIG. I couldn't do that.

As shown in the figure, core metals 6 are embedded in rows at regular intervals along the length of the endless band 1 made of an elastic material.
An engagement hole 7 is provided at the center of the strip between the core metals 6, and a main lug 5A is provided on the grounding surface side of the endless band 1. The main lugs 5A are distributed and formed at regular intervals in the longitudinal direction, and are separate from each of the main lugs 5A.
A shorter auxiliary lug 5B is arranged at the center of the band width within the projection area of the core bar 6, and the height of the ground surface of the auxiliary lug 5B is formed lower than the height of the ground surface at the starting end of each main lug 5A. be.

で充分でない。(Problems to be Solved by the Invention) The device shown in FIG.
B is located, and considering the symmetrical arrangement of the lugs 5A and the arrangement of the lugs 5B at regular intervals in the center, the ground planes are arranged approximately evenly, which is effective in terms of vibration generation. The existence of the lugs 5A and 5B means that the overlapping portion has very high rigidity, while the portion of the lug 5A that is outside the projection area, especially the starting end portion near the engagement hole 7, has a lower rigidity than the overlapping portion.
When the rollers 4 and the like pass through this portion, a depression phenomenon occurs, although this may be an exaggeration, and vibration occurs here. On the other hand, in the case shown in FIG. 11, the main lug 5A, including the slope surrounding the ground surface of the lug, is completely shifted from the projection area of the core bar 6, and the core bar 6 portion and the main lug 5A Although it is excellent in that there is little difference in rigidity between parts, and in addition to the presence of the auxiliary lug 5B, there is little vibration, it is not sufficient in terms of traction force and earth removal performance.
