PROBLEM TO BE SOLVED: To provide a pin connecting structure for a working machine, which is improved in sealing performance of a seal fitted onto a peripheral portion of abutting end faces of relatively rotatable two members, the seal preventing infiltration of earth and sand, to thereby prevent damage of a pin by earth and sand. SOLUTION: The pin connecting structure is formed of the pin rotatably connecting the two members in a relatively rotatable manner, the annular seal fitted onto a peripheral groove defined by the peripheral portions of the respective abutting end faces of the two members, and a cylindrical seal cover covering the seal. According to the pin connecting structure, the seal cover is fitted onto one of the two members beforehand, and then the seal is compressed into the peripheral groove, followed by moving the seal cover to the peripheral portion of the seal, to thereby cover the seal. |
