PURPOSE: A vibration preventing device for coke oven chamber temperature measuring instrument is provided to produce coke of high quality by installing a temperature instrument at one side of ram for extruding coke in such a way that vibration generated in the ram is not transferred to the temperature instrument to prevent measurement error of the temperature instrument. CONSTITUTION: The vibration preventing device for coke oven chamber temperature measuring instrument comprises a supporting rod(20) installed at the center of the ram so that the supporting rod is exposed to a through hole formed at a selected position of a ram reciprocated inside coke oven chamber; a fixed ring(30) inserted onto the outer circumferential surface of the supporting rod with being spaced apart from the supporting rod in a certain distance; at least two or more of thermometers(11) inserted into the fixed ring; a plural inner fixing means installed in the supporting rod in such a manner that the inner fixing means are capable of being projected to the outer circumferential surface of the supporting rod; and a plural outer fixing means installed in the fixed ring in such a manner that the outer fixing means are capable of being projected to the inner circumferential surface of the fixed ring so that the outer fixing means correspond to the inner fixing means, wherein a protection plate(40) is installed on the outer surface of the fixed ring to protect the thermometers, wherein four of the inner and outer fixing means are installed in an angle distance of 90 degrees, and wherein the inner fixing means comprise inner moving block(21), inner magnet and inner spring(23), and the outer fixing means comprise outer moving block(31), outer magnet(32) and outer spring(33).
