補助具本體（4)係將長方形的彈性金屬板實施沖切及 彎折加工而形成者，且在其中央部開設有供上述螺釘（6)穿 通用的穿透孔（41)，而穿過該穿透孔（41)的螺釘（6)即得以 螺入上鞍座夾（21)上面中央之螺絲孔（25)。 於補助具本體（4)之長度方向的兩端部施以彎折加 工，而作為形成有朝下方敞開之大致半圓筒狀螺帽保持部 的外嵌凹部（42)(42)。該外嵌凹部（42)(42)之内周具有吻 合柱狀螺帽（23) (23)外周的形狀，同時在上述外嵌凹部 (42) (42)的形成部上，形成有於前後端開放的缺口 (43) (43)。 其次，說明鞍座（5)的安裝作業。 進行鞍座（5)的安裝作業前，先在上鞍座夾（21)上裝設 柱狀螺帽（23)(23)。 具體而言，將柱狀螺帽（23)裝入於上鞍座夾（21)上面 12 1290890 所形成的凹部（213)(213)，且在該狀態下，將補助具本體

[3]·上述第1實施型態中，係在上鞍座夾（21)的上面 形成供裝設柱狀螺帽（23)(23)的凹部（213)(213)，然而不 一定要設置該凹部。此乃因為柱狀螺帽（23) (23)得以藉著 補助具本體（4)的外嵌凹部（42)(42)保持在穩定狀態之故。 名2貫施举辑 第4圖係關於本發明第2實施型態之補助具（A)的說明 圖’圖（a)係補助具本體（4)的俯視圖，圖（b)係其侧視圖。

折而形成第2結合用嵌合凸部（44b)(44b)。 此外，柱狀螺帽（23)係具有貫穿於直徑方向的螺絲孔 (231)以及形成於其兩侧且與轴線形成直角的一對扣合溝 (230)(230)。 在此構造中，將柱狀螺帽（23)(23)嵌入補助具本體（4) 的外嵌凹部（42)(42)内，同時將補助具本體（4)的長邊部 (46)(46)嵌入柱狀螺帽（23)上面的扣合溝（230)(230)。在 此狀態下，與第4圖同樣的，將第2結合用嵌合凸部（44b) 強制嵌入形成於上鞍座夾（21)隆起部（24)的第1結合用嵌 合凹部（215)時，補助具本體（4)即得以安裝於上鞍座 (21)。因此，被補助具本體（4)之外嵌凹部（42)(42)握持的 柱狀螺帽（23)(23)可保持於上鞍座夾（21)上面的螺帽座位 置。在此構造中，具有與上述第2實施型態相同的效果。

(6)穿通用的穿透孔（49)係穿設於上下方向。另一方面，在 柱狀螺帽（23)的兩端，形成有供外嵌於上述第2嵌合凸部 (480)(480)之第1嵌合凹部（232)(232)，同時在軸向的中 央部形成有貫穿於直徑方向的螺絲孔（231)。 在此構造中，將柱狀螺帽（23)插入強制擴張的彈性臂 架（48)(48)前端之間，其次，藉由令彈性臂架（48)(48)恢 復原本的形狀，即可令第2嵌合凸部（480)(480)嵌合於該 柱狀螺帽（23)兩端的第1嵌合凹部（232)(232)。在此狀態 下，將補助具本體（4)疊合於上鞍座夾（21)上面，並以螺釘 (6)將其固定於上鞍座夾（21)上時，柱狀螺帽（23)即可保持 於上鞍座夾（21)上面的螺帽座位置。然後，利用與第1圖 17 1290890 相同的方式來安裝鞍座（5)。 <變形例> [1]
