PURPOSE: A pin fusion system for CRT panel is provided to allow the elevating position of post member to be easily adjusted in accordance with the size of CRT panel. CONSTITUTION: A pin fusion system comprises a support unit(30); a post member(31) coupled to the support unit, and which has a measurement tip(32) arranged at an end of the post member, in such a manner that the measurement tip contacts an inner surface of a panel(22) and measures displacement in the axial direction of the panel; and an elevating unit interposed between the support unit and the post member, and which permits the post member to elevate with respect to the support unit in such a manner that the measurement tip is movable between an operating position where the measurement tip contacts the inner surface of the panel and a retrieval position where the measurement tip deviates from the panel. The elevating unit includes a transmission shaft(37) shaped as a long rod, and disposed beneath the post member; a rotatable adjustment piece(38) disposed at the transmission shaft; and a gear assembly(40) interposed between the transmission shaft and the adjustment piece, and which converts a rotating motion of the adjustment piece into a linear motion of the transmission shaft.
