PROBLEM TO BE SOLVED: To provide a cab structure of a working machine that can easily and effectively enhance the strength of a cab and flexibly deal with a demand for constituting the cab more robustly. SOLUTION: A cab structure (A) of the working machine is formed so that a plurality of pillars 6 (7 and 8) and a plurality of beam members 9 are assembled in a box shape by installing gusset plates 11 with corners S1, S2, and S3 where the pillars 6 (7 and 8) are coupled to the beam members 9. The cab structure includes gusset reinforcement members 13 attached to the gusset plate 11 (12) of the corner part S1, respectively, which receives a compression force when the working machine falls down in order to enhance the strength performance of the gusset plates 11 (12).
