PURPOSE: An automatic draft quantity measuring device for a tundish nozzle is provided to automatically measure the airtightness and draft of a tundish nozzle by sealing the tundish nozzle and supplying compressed air into the tundish nozzle. CONSTITUTION: An automatic draft quantity measuring device for a tundish nozzle comprises a rotating body(110), a plurality of fixing members(120), a support body(130), a moving body(140), a first motor(133), an auxiliary body(150), a second motor(143), and a measuring sensor(151). The rotating body is equipped with a driving member(111) on a side. The fixing members fix a tundish nozzle. A horizontal rail(131) is formed on the top of the support body. A vertical rail(141) is formed in the vertical direction on a side of the moving body. The first and the second motor rotate a first and a second helical axis, respectively. The measuring sensor measures the draft of gas generating inside the tundish nozzle.
