PROBLEM TO BE SOLVED: To provide a spacer for a lock bolt, capable of enhancing versatility by coping with two kinds of outer diameter dimensions, capable of reducing cost by reducing the specification number by half thereby, and capable of improving fitting workability by easily distinguishing by visual observation when installed on the lock bolt.SOLUTION: A spacer comprises a belt-like base part 7, four guide parts 6 for partitioning a first space S1 formed at the same opening angle by facing to the base part and a second space S2 formed at the same opening angle on both sides of the base part and a recessed part 8 formed by one so as to communicate with all of the first and second spaces and inserting lock bolts 1A and 1B, and a first lock bolt receiving groove R1 of a large groove width dimension regulated by the mutual guide parts for partitioning the first space is formed by the recessed part, at the same time, a second lock bolt receiving groove R2 of a small groove width dimension regulated by the mutual guide parts for partitioning the second space is formed. |
