また、第８図に示したように、ハトメ１１の座
部１２から貫通孔７付近の帯体８の一部が露出し
て、商品価値をなくすことがあつた。 Further, as shown in FIG. 8, a part of the band 8 near the through hole 7 was exposed from the seat 12 of the eyelet 11, thereby losing its commercial value.
この場合、ハトメ１１の座部１２から貫通孔７
付近の帯体８の一部が露出しないようにするた
め、この座部１２の厚さを厚くする必要があつ
た。 In this case, from the seat 12 of the eyelet 11 to the through hole 7
In order to prevent a portion of the band 8 in the vicinity from being exposed, it was necessary to increase the thickness of the seat 12.
