The present invention relates to a height adjustment ring spacer, including a ring-type gasket with at least one upper ring body and one lower ring body, in which plural staircase-type ladders formed in a side of each of the upper ring bodies and a side of each of the lower ring bodies make the ladders of the upper ring body and the lower ring body individually be placed at different linking engagements to increase or decrease the height in circumferential direction; the features of the present invention are that: there are a recess formed in every ladder of the above upper ring body, and a convex body formed in every ladder of the lower ring body, thus the recess of the upper ring body and the convex body of the lower ring body relatively plug and link each other to avoid the relative movement in circumferential and radial direction therein. |
