Claim:
A sliding gate assembly comprising: an upside frame including a fixed plate formed with a first nozzle hole; a suspending frame which equips a pressing member; a slide frame adapted to be slidingly moved along said suspending frame, said slide frame being provided with an inclined block on the longitudinal side surface thereof and a sliding plate formed with a second nozzle hole; a pressing member for pressing an elastic body to said suspending frame; and a cotter adapted to be detachably inserted through said pressing member onto a slide frame, wherein said inclined block is adapted to be brought into slide contact with said cotter to compress said elastic body so as to load a given surface pressure on the opposed surfaces of said fixed and sliding plates, said sliding gate assembly being characterized in that: said inclined block is located at a position on said longitudinal side surface of said slide frame, said inclined block being formed with an inclined surface which is reduced in height in a direction allowing said first and second nozzle holes to be fully closed, and said slide frame includes a stopper member which is located at a position on said longitudinal side surface thereof and close to said second nozzle hole of said sliding plate, so as to prevent said first and second nozzle holes from being fully opened in the state as said cotter is inserted through said pressing member onto a slide frame.
