PROBLEM TO BE SOLVED: To inhibit failures caused by vibrations of a control device (a CPU substrate) in an operation part when a roll gap is measured by using a roll gap measuring apparatus installed at a dummy bar.SOLUTION: A roll gap measuring apparatus of the invention includes: a roll gap measuring sensor; an operation part 23 in which a control device (a CPU substrate) 23a for calculating a roll gap from an output signal of the roll gap measuring sensor and storing the calculated roll gap is installed; and a power source which supplies electric power to the control device. The roll gap measuring apparatus is attached to a dummy bar. The operation part 23 comprises: an outer case 26; an inner case 27 which is stored in the outer case; and the control device (the CPU substrate) 23a. The control device (the CUP substrate) is fixed to the inner case, and a vibration control material for inhibiting vibrations of the control device (the CPU substrate) is disposed between the outer case and the inner case.SELECTED DRAWING: Figure 5 【課題】 ダミーバーに設置されたロール開度測定装置を用いてロール開度を測定するにあたり、演算部内の制御装置（ＣＰＵ基板）の振動に起因する故障を抑制する。【解決手段】 本発明のロール開度測定装置は、ロールギャップ計測センサと、ロールギャップ計測センサの出力信号からロール開度を演算し、演算したロール開度を記憶するための制御装置（ＣＰＵ基板）２３ａを内装する演算部２３と、前記制御装置に電力を供給する電源とを備え、ダミーバーに装着されたロール開度測定装置において、前記演算部２３は、外箱２６と、該外箱の内部に収納される内箱２７と、制御装置（ＣＰＵ基板）２３ａとで構成され、前記制御装置（ＣＰＵ基板）は内箱に固定され、外箱と内箱との間に、制御装置（ＣＰＵ基板）の振動を抑制するための防振材料が配置されている。【選択図】 図５
