That is, when the first fastening portion 24 of the first body fastening hole 20 corresponds to one end of the gate body 10 and is pushed together, one end of the gate body 10 is moved into the first fastening portion 24. The insertion is completed while being supported by the internal step.

Then, when the second fastening portion 35 of the second body fastener 30 corresponds to the other end of the gate body 10 and is pushed together, the other end of the gate body 10 is inserted into the second fastening portion 35. do. Therefore, as the first body fastening device 20 and the second body fastening device 30 are pushed into both ends of the gate body 10 in one operation, they can be easily and quickly combined with each other, thereby improving assembly performance.

The first body fastener 20 and the second body fastener 30 are coupled to the gate body 10, and then the fixing pin 80 is coupled to the first body fastener 20 and the second body fastener ( 30 is not to be separated from the gate body (10).

Guide jaws 46 are formed on both sides of the discharge port body 41 of the discharge port 40. And the first fastener sphere body 21 of the first body fasteners 20 is formed in a circular shape. Therefore, when the gate body 10 assembly formed by combining the gate body 10, the first body fastening device 20, and the second body fastening device 30 enters the casing 1, the first body fastening device The first fastener sphere body 21 of 20 is guided to the center side of the discharge hole 40 even if it is not located at the top center of the discharge hole body 41.

That is, even if the first fastening body 21 of the first body fastening hole 20 is lowered slightly to one side from the center of the discharge port body 41, the center of the first fastening part body 21 is the guide jaw. The first fastening body 21 which is lowered is guided between the pair of guide jaws 46 unless it deviates from 46.

Therefore, even if the center of the first body fastener 20 and the center of the discharge port 40 do not exactly match each other, the first body fastener 20 is guided to the center side of the discharge port 40 and is accurately set.
