PURPOSE: An assembly structure of a shutter plate in a draw-out type air circuit breaker is provided to simplify an assembling process by combining the shutter plate with a front side of a cradle within a short time. CONSTITUTION: A cradle of a draw-out type air circuit breaker includes a frame(2), a main circuit conductor(4), a shutter(5), a shutter unit assembly(6), and a shutter plate(7). The frame(2) has an open front side. The main circuit conductor(4) is installed within the frame(2) to connect a power line to a load line. The shutter(5) is used for opening or shutting a connection path. The shutter plate(7) is coupled to a front side of the shutter(5). A combination structure of the shutter plate in the drawer type air circuit breaker includes a combination structure of the shutter plate(7) and the frame(2) of a cradle(1). A screw combination portion is formed at an upper end of the shutter plate(7). An insertion section is formed at a lower end of the shutter plate(7). An insertion groove is formed at the frame(2) of the cradle(1). The insertion section of the shutter plate(7) is inserted into the insertion groove of the frame(2) of the cradle(1). A combination screw(10) is combined with the screw combination portion of the shutter plate(7).
