The gripping plate(12) of the jig is placed under the ceiling air duct(2). With the inner main supporter(10) supporting the air duct(2) at the inner position, the pedal which is fixed to the inner main support around the fixed shaft(26) is turned downward and stopped thereon, then the ceiling panel(1) and the ceiling air duct(2) located between the inner main support(10) and the panel(18) are pressed at the same time. At this time, the outer support bar(22) is pulled forward and the inner supporting bar(30) pressed down, then as the working main body(30) goes down, the benting roller(32) moves around the fixed shaft(26) in a circular move and bents the upper end of the ceiling air duct(2), fixing it to the ceiling panel(1).
