PROBLEM TO BE SOLVED: To provide a safe bicycle wheel installing metal fitting aggregate, simple in attaching-detaching a wheel, hardly derailing and small in protrusion in the vehicle width direction.SOLUTION: An installing metal fitting aggregate is constituted of a first installing metal fitting 1 having a hollow structure by applying counterbore processing to a neck part 11, a second installing metal fitting 2 for forming a female screw on a hollow inner wall, a flush bolt 3 with a hexagonal hole having a male screw part in a shaft part and first-second spacers 4 and 5 having a through-hole and an auxiliary hole and sandwiched between the installing metal fitting and a frame. Since a plane is formed in neck lower parts 12 and 22 of the first-second installing metal fittings and is fitted-fixed to an U-shaped installing part on the frame side, corotation is not caused when using a wrench. Since the first-second spacers are fastened by a bolt to a washer claw engaging hole of the frame by using the auxiliary hole, derailment can be surely prevented. Since a head part 31 of the flush bolt 3 is stored in a seat part of the first installing metal fitting 1, it becomes a thin type safe structure.SELECTED DRAWING: Figure 2

    【課題】ホイールの着脱が簡単で、脱輪しにくく、車幅方向への出っ張りが小さい、安全な自転車用ホイール取付け金具集合体を提供する。【解決手段】首部11に座ぐり加工が施され中空構造を有する第1の取付け金具1、中空の内壁に雌螺子が形成された第2の取付け金具2、シャフト部に雄螺子部を有する六角穴付き皿ボルト3、通し穴と補助穴を有し取付け金具とフレームの間に狭設される第1・第2のスペーサー4・5によって構成される。第1・第2の取付け金具の首下部12・22には平面が形成されフレーム側のコの字形状の取付け部に嵌合・固定されるため、レンチ使用時に供回りが発生しない。第1・第2のスペーサーが補助穴を使用してフレームのワッシャー爪係合用穴にボルト止めされるため、脱輪を確実に防止できる。皿ボルト3の頭部31が第1の取付け金具1の座部に収まるため、薄型の安全構造となっている。【選択図】図2
