PROBLEM TO BE SOLVED: To provide a crawler frame provided with a machine body frame integrally formed by a molding means. SOLUTION: The machine body frame 25 consists of a pair of front legs 12 and rear legs 14, and a center frame 10 is integrally formed by a molding means as a continuous curved shape by a smooth curved surface. By this constitution, even if a load and a working load from an upper revolving body 3 applied to the center frame 10, and a working load applied to a track frame 16 at the time of traveling, revolving and working of a working machine 8 are applied to the machine body frame 25, the occurrence of a concentrated load by these loads is prevented, and these loads can be received evenly by the entire machine body frame 25.
