CRAWLER BELT AND SEAL FOR USE THEREIN

摘要

A seal (21) comprising a link side lip part (22) abutting against the outer link part (9) of a cover belt (7), a bush side lip part (23) abutting against a bush (11), and an intermediate linking part (24) for linking the lip parts (22, 23). A relation (T2≅T2'> T1≅T1') is set, where (T1, T2, T1', T2') are the thickness dimensions at the link side lip part (22), the bush side lip part (23), a link side linking part (24A) and a bush side linking part (24B). Maximum outside diameter part (24C) side of the intermediate linking part (24) is located on the radial outside of the radial intermediate position of the bush side lip part (23). The bush side lip part (23) is pushed entirely and uniformly toward the end face (11A) of the bush (11) by the intermediate linking part (24).
