Basically, the column head cover 10 of the first embodiment is divided into two parts at both sides at the vertical center. The head cover is divided into two parts on both sides at a vertical center part to form a pair of divided head covers 12a, and the upper end fitting part is formed at the center of the divided edge of the upper plate divided parts 12e formed along with the division. A pair of divided fitting portions 13a provided on the lower surface of the portion, and the column fitting holes are formed by both lower plate divided portions 12f formed along with the division.
Are formed in a pair of semicircular fitting holes 14a provided at the center of the divided edge. The upper connecting portion 16 has basically the same structure as the connecting portion 5 of the first embodiment, and is opposed to both upper plate divided portions 12e formed along with the division. As described above, the lower connecting and cover fixing portion 15 has basically the same structure as the connecting portion 5 of the first embodiment, and is formed of two lower plate divided portions 12e formed along with the division. The upper connecting portion 16 and the lower connecting / cover fixing portion 15 are opposed to the lower surface, and both the washer and the bolt / nut 6
The upper plate dividing portion 12e and the lower plate dividing portion 12f are tightened and connected by bolts, nuts and the like of the concave portions 16b, 15b.
The split head cover 12a is disposed in the
The structure is fixed to 1. The diameter of the column fitting hole formed by the pair of semicircular fitting holes 14a is equal to the column cover 30.
Alternatively, it is formed corresponding to the diameter of the column head a1.

The above-mentioned divided strut head cover 20 is attached to the strut a if necessary by covering the strut a with a strut cover 30, and then the pair of split head covers 12a, which are divided into two on both sides, are attached to the strut a.
1 and the upper connecting portion 16 and the lower connecting / cover fixing portion 15 and the both upper plate dividing portions 1
By tightening and connecting 2e and both lower plate divisions 12f, it is possible to more easily and accurately cover the back side of the rail mounting portion together with the column head a1 or the column a total length,
Basically, the same operation and effect as those of the first embodiment can be obtained.

The specific structure of the cover fixing portion 5, the lower connecting / cover fixing portion 15, the upper connecting portion 16, and the like in each of the above-described embodiments is not limited to the illustrated example but can be variously modified.
Further, the pillar cover 30 can be used not only for guardrails but also for covering pillars of various facilities.
