<p>A track belt assembly (22) has a track shoe (25) and a pair of parallel links (26) fixed by bolts (36) to that surface of the track shoe (25) which does not engage the ground. A connection shaft (27) is fixed to shaft holes (31) formed in end portions of the links (26). A reinforcement member (48) connects the link (26) together with the use of bolts (36), thus reinforcing an opening between the links (26). As a result, breakage of the links (26) caused by concentration of stress to a specific portion of the links (26) is prevented.</p> |
