PURPOSE:To facilitate disassembling and assembling by forming a stepped part on one end part of a master pin which connects regular links to master links in a crawler belt used in a crawler vehicle, and engaging a stopping member with the stepped part to prevent said pin from coming off. CONSTITUTION:A crawler belt 1 has each pair of regular links 2, 2... which are connected to each other in order via track pins, and master links 41, 42 which connect the regular links 2, 2 which are adjacent to each other in the connected direction. The outside link parts of the master links 41, 42 are connected to the regular link 2 on the other side in the connected direction, by means of a master pin 47. And, a shoe 19 is fixed to the outside of the links. A fitting hole 43 into which one end part 47A of the pin 47 the other end part 47B of which is press fitted in the fitting hole 44 of the master ring 42, is loosely fitted, is formed on the master link 41, while also forming an annular groove 46 on a part near its outside, and a C-shaped stopping member 50 is fitted in the annular groove 46 to make the stepped part 49 of the one end part 47A of the pin engagedly stopped. |
