The tool box includes a first cover and a second cover pivoted with and correspondingly coverable on each other on a side thereof The first cover has a pivoting base, and the second cover has a clasping base. The anti-off structure includes an engaging member and a positioning member. The engaging member includes an engaging portion, and an end thereof is pivoted to the pivoting base via a pivoting connection mechanism; therefore, the engaging portion is buckleable with the clasping base when the first and second covers cover on each other. The positioning member is connected with the pivoting connection mechanism and the pivoting base to positionably restrict the pivoting connection mechanism.
