摘要： PURPOSE:To provide a bolt turn stopping device which is easy to mount and dismantle and which can be reused. CONSTITUTION:A hexagonal hole 6a-1 is formed in the head 6a of a bolt 6 which penetrates an object to be fastened 7 and is put in screw engagement with another object to be fastened 8, and a hexagonal rod 1 is inserted in this hexagonal hole 6a-1 and becomes unrotatable relative to the bolt 6, and an axial direction through hole 2a to be fitted on the hexagonal rod 1 and become unrotatable relative to the hexagonal rod 1 and a peripheral threaded part 2b in leftwise threads are provided, and this is put in screw engagement with a leftwise threaded part 7a-1 formed at the peripheral surface of a countersunk hole 7a bored in the object 7. The arrangement further includes a lock plate 2, which is thereby put in contact with the oversurface of the head of the bolt 6, and a holder plate 3 which is attached to the lock plate 2 and engaged by the hexagonal rod 1 inserted in the through hole 2 in the lock plate 2 so that the hexagonal rod 1 does not slip off from the through hole 2a.
