A leaf chain (3) comprises a plurality of connected links (31) each includes at least two aligned pins (311), first inner plates (312), second inner plates (313), and two outer plates (314) . A washer (315) is disposed at both peripheries of each hole (3121) of the first inner plate (312), and a bushing (316) is sleevedly disposed on the pin (311) and inserted into each hole (3121) of the first inner plate (312). Such arrangement prevents the lubricant held within the first inner plate (312) from leaking and attains a preferable lubricating effect and a stable transmission to efficiently prevent the leaf chain (3) from being worn away at the first inner plates (312) and pins (311) and increase the life of the leaf chain (3). |
