To provide a tightening member that can always tighten an object at a constant torque.SOLUTION: A tightening member 1 includes a torque limit mechanism that notifies a user of that tightening has been performed with a torque greater than or equal to a predetermined level by idle rotation of a first member 10 with respect to a second member 20, and a display 3 that displays an unusable state of the tightening member 1 when the torque limit mechanism has operated a specified number of times. The display 3 includes an opening 16 and a mark 29, in which the mark 29 becomes visible through the opening 16 to display the unusable state when the tightening member 1 has been used a specified number of times.SELECTED DRAWING: Figure 2
【課題】常に一定のトルクでの締め付けが可能な締め付け部材を提供する。【解決手段】締め付け部材1は第一部材10が第二部材20に対して空回りすることによって所定以上のトルクでの締め付けが行われたことを通知するトルクリミット機構と、前記トルクリミット機構が規定回数作動した時に、前記締め付け部材1の使用不可状態を表示する表示部3を備える。表示部3は開口16及び印29から成り、締め付け部材1が規定回数使用された際に、開口16から印29が視認可能となることで使用不可状態を表示する。【選択図】図2
