The master pin (22) is inserted into first and second through holes (21a 31a). In the master pin (22) an insertion hole (22b) is formed. The rotation stop pin (25) is pressed into the insertion hole (22b) and both ends thereof protrude from the master pin (22). The snap ring (26) has a C shape has a larger outer diameter than the first through hole (21a) and is located on the opposite side to the second crawler link (31) with respect to the first through hole (21a) and attached to the master pin (22). A groove (31b) has a width narrower than the diameter of the master pin (22). The rotation stop pin (25) is disposed within the groove (31b). |
