A tool box includes a housing having a number of orifices formed in an upper wall, and a carrier slidably received in the housing and having a number of socket openings for receiving tool members. The carrier is slidable relative to the housing for selectively moving the tool members in and out of the housing. A spring member may be engaged between the housing and the carrier, for biasing the carrier to move the tool members out of the housing. The carrier includes a bore for slidably receiving a guide post of the housing, and for guiding the carrier to move up and down relative to the housing. An anchoring device may anchor the carrier to the housing at the inwardly storing position.
