description	PROBLEM TO BE SOLVED: To solve a problem that it is difficult to know a tightening force (an axial force) of a bolt easily and accurately during tightening or maintenance of the bolt.SOLUTION: An axis is provided inside a bolt to install an enlargement mechanism of a displacement difference using fluid that enlarges the displacement difference between the axis and the bolt during tightening for visual check, thereby enabling a user to know a tightening force (an axial force) of the bolt easily. 【課題】ボルトの締付け時およびメンテナンス時に簡単にかつ精度よくボルトの締付け力（軸力）を把握することが困難であった。【解決手段】ボルト内部に軸を設け、締付け時に発生する軸とボルト変位差を目視できるように拡大するため、流体による変位差の拡大機構を設けることによって容易にボルトの締付け力（軸力）の把握が可能となった。【選択図】図１
