PURPOSE: A device for adjusting the ascending/descending of a smoke intake pipe is provided to prevent the upper part of a roaster from becoming contaminated due to the oil components flowing along the inner circumferential surface of the smoke intake pipe. CONSTITUTION: A device for adjusting the ascending/descending of a smoke intake pipe comprises an upper pipe(110), a lower pipe(120), a connecting pipe(130), an elastic support(140), and an oil blocking ring(150). The upper pipe guides the smoke and the smell from a roaster to a discharge duct along the intake air. The upper end of the upper pipe is connected and fixed to the discharge duct. Some sections of the lower pipe are inserted into the inside of the upper pipe and are installed to be able to move vertically with respect to the upper pipe. The connecting pipe connects the upper pipe to the lower pipe, the lower end of the connecting pipes is integrally formed with its upper end of a different diameter, the lower end is inserted and fixed to the upper end of the lower pipe and the outer diameter of the upper end is larger than the outer diameter of the lower pipe. The inner diameter of the upper end is smaller than the inner diameter of the upper pipe. The elastic support is fixed to an operating hole formed in the connecting pipe. The oil blocking ring is installed in a ring groove formed on the connecting pipe and blocks the oil components flowing along the inner surface of the upper pipe from directly falling onto the upper part of the roaster.
