Zusammenfassung:	To provide a mold clamping device capable of precisely detecting a mold tightening force without increasing the number of components of a mechanical part.SOLUTION: A mold clamping device 10 is provided with a fixed platen 11 for holding a fixed mold 14; a movable platen 12 for holding a movable mold 15; a toggle link mechanism 23 for allowing the movable platen to approach or separate from the fixed platen; and a strain sensor 26 for detecting a strain of a link element included in the toggle link mechanism. The strain sensor is installed on a holding area where extension or shrinkage caused by a bend generated on the link element are cancelled.SELECTED DRAWING: Figure 2 【課題】機構部分の部品数を増加させることなく型締力を精度よく検出できる型締装置を提供する。【解決手段】型締装置１０は、固定金型１４を保持する固定盤１１と、可動金型１５を保持する可動盤１２と、可動盤を固定盤に対して接近または離間させるトグルリンク機構２３と、トグルリンク機構に含まれるリンク要素のひずみを検出するひずみセンサ２６と、を備える。ひずみセンサは、リンク要素に生じる曲げによる伸びおよび縮みが相殺される保持領域に取り付けられる。【選択図】図２
