Elastic crawler with core metal

A construction vehicle including a crawler traveling device including a driving sprocket, rollers, and an elastic crawler (10) with core metals (20) embedded in an endless belt-shaped elastic body (11) made of an elastic material at constant intervals in a crawler circumferential direction, the elastic crawler with core metals having a configuration in which

• a core metal main body (21) elongated in a crawler width direction of the core metal (20) includes a central engagement portion (21a) with which a driving sprocket (2) is engaged, a pair of guide protrusion bases (21b) formed at opposite ends of the central engagement portion (21a), and a pair of core metal blade parts (21c) extending laterally to opposite sides to each other from the pair of guide protrusion bases (21b),
• a pair of guide protrusions (22) protrudes from the pair of guide protrusion bases (21b) to a crawler inner circumference side,
• the core metal (20) is embedded in the endless belt-shaped elastic body (11) except for at least the guide protrusions (22), and
• rollers (5) arranged along a longitudinal direction of the elastic crawler and roll on a top of the guide protrusion (22), wherein
• the elastic crawler (10) comprises:
• roller disengagement preventing protrusions (23A, 23B;
• 24A, 24B) respectively protruding in opposite directions of the crawler circumferential direction from each of the pair of guide protrusion bases (21b, 21b) of the core metal main body (21), each of the roller disengagement preventing protrusions (23A, 24A;
• 23B, 24B) meshing with the corresponding roller disengagement preventing protrusions of the adjacent core metal in the crawler width direction;
• and
• ribs (25, 25) connecting each of the roller disengagement preventing protrusions (24A, 24B) located at the side of the core metal blade parts (21c, 21c) with the corresponding core metal blade part (21c, 21c).
