A casing locking structure of an electronic device is provided to increase reliability of products by providing a stable casing through the support in three axial directions. A casing locking structure of an electronic device includes a front casing(10), and a middle casing(20). The front casing(10) has a side wall(12) and a connection hook(14) which is downwardly formed on the side wall(12). The middle casing(20) has a side wall(22), a connection groove(24), and a connection protrusion(26). The side wall(22) is assembled to be closely adhered to an outer side of the side wall(12) of the front casing(10). The connection groove(24) is formed on the side wall(22). The connection protrusion(26) is formed on the side wall(22) to form a connection groove unit on an upper part between the side wall(22) and the connection protrusion(26). The front casing(10) and the middle casing(20) regulate upward/downward and front/rear movements in a state that the connection hook(14) is connected to the connection groove(24). Left/right movement are regulated by connecting the side wall(12) to a connection groove unit.
