The invention provides a track main body, which can ensure the bendability of the track main body and can prevent vertical vibration of rollers when the rollers span the extension parts of the core bars as much as possible. The crawler main body is provided with core bars (10) buried in the crawler main body (9) at substantially equal intervals, and rolling paths (12, 13) for rollers disposed on both sides of the crawler main body (9) in the width direction of the crawler on the side opposite the ground contact surface. Protruding parts (24-27) are provided on both sides of each core bar (10) in the direction of rotation of the track, the protruding parts (24-27) protruding from the core bars (10) toward both sides in the direction of rotation of the track and supporting the rolling paths (12, 13), and at least the tip parts of the protruding parts (24-27) of each core bar (10) corresponding to the rolling paths (12, 13) are disposed so as to be offset from each other in the width direction of the track within the width of each rolling path (12, 13). The tip of the protruding section (25) of one of the core bars (10) and the tip of the protruding section (26) of the other core bar (10) are disposed close to or overlapping with each other in the direction of rotation of the crawler belt.

    本发明提供一种履带主体,能够确保履带主体的弯曲性,并且能够尽可能防止滚轮在跨越各芯骨的伸出部时的上下振动。履带主体具备在履带本体(9)内空开大致相等间隔地埋设置有芯骨(10)和在履带本体(9)的接地相反面侧的履带宽度方向上的两侧配置的滚轮用的滚动路(12、13),在各芯骨(10)的履带转动方向上的两侧具备从各芯骨(10)向履带转动方向上的两侧伸出并支承各滚动路(12、13)的伸出部(24~27),各芯骨(10)的与各滚动路(12、13)相对应的各伸出部(24~27)的至少顶端部彼此在各滚动路(12、13)的宽度内在履带宽度方向上错开配置,各芯骨(10)中的一个芯骨(10)的伸出部(25)的顶端和另一个芯骨(10)的伸出部(26)的顶端在履带转动方向上靠近或重叠配置。
