Zusammenfassung:	To provide a jig for displacement measurement allowing installation work of PC steel strands to be carried out easily and securely and accurate measurement to be performed to measure displacement of the PC steel strands when introducing tension force for the PC steel strands by applying tension with a tension jack.SOLUTION: A jig 3 for displacement measurement is for measurement when introducing tension force for the PC steel strands W by applying tension with a tension jack 1. The jig for displacement measurement is provided with; a fixation part 30 detachably fixed on the PC steel strands; a bar-like part 4 attached so as to project from the fixation part; and an engaging part 5 making an end part 211 of a measurement wire 21 extending from a displacement meter 2 attached on a tension jack engaged with the bar-like part.SELECTED DRAWING: Figure 1 【課題】緊張ジャッキによりＰＣ鋼より線を緊張して緊張力を導入する際にＰＣ鋼より線の変位を計測するために、簡易かつ堅固に設置作業を行うことが可能であるうえに、正確な計測を行うことができるようになる変位の計測用治具を提供する。【解決手段】緊張ジャッキ１によりＰＣ鋼より線Ｗを緊張することで緊張力を導入する際に計測される変位の計測用治具３である。そして、ＰＣ鋼より線に着脱自在に固定される固定部３０と、固定部から突出するように取り付けられる棒材部４と、緊張ジャッキに取り付けられた変位計２から延伸される計測用ワイヤ２１の端部２１１を棒材部に係止させる係止部５とを備えている。【選択図】図１
