摘要：
A track chain assembly (22) has a track shoe (25) and a pair of parallel links (26) that are fixed to a non ground-engaging surface of the track shoe (25) with bolts (36). A connecting shaft (27) is fixed to shaft holes (31) that are provided on end portions each of which is included in the links (26). A reinforcing member (48) connects the links (26) with the bolts (36) so as to reinforce an open side between the links (26). Therefore, the links (26) are prevented from being damaged due to concentration of stress on a specific portion of each link (26).
