Abstract:
1. A bicycle wheel securing structure comprising: a bicycle fork having a pair of axle support portions that are spaced apart to receive a bicycle hub therebetween and with one of the axle support portions having an adapter receiving bore that includes an enlarged section, a reduced section and an abutment surface, the reduced section being concentrically and axially arranged relative to the enlarged section, the reduced section having a smaller diameter than the enlarged section, the abutment surface being formed between the enlarged section and the reduced section such that the abutment surface faces in an axial direction of the adapter receiving bore; an adapter disposed in the enlarged section of adapter receiving bore in one of the axle support portions, with the adapter including a threaded axle mounting opening, an axially facing surface that faces in an axial direction of the threaded axle mounting opening, and an outer circumferential surface, the abutment surface of the adapter receiving bore contacting the adapter to prevent first axial movement of the adapter with respect to the bicycle fork in a first axial direction along an axis of the axle mounting opening; and a holding member operatively coupled between the adapter and the one of the axle support portions with the adapter, the holding member including an attachment portion that is attached to the bicycle fork, and an engagement portion that is selectively movable between a retaining position and a releasing position, the engagement portion prevents both rotational movement of the adapter with respect to the bicycle fork and second axial movement of the adapter with respect to the bicycle fork in a second axial direction that is opposite of the first axial direction along the axis of the axle mounting opening while the holding member is in the retaining position with the engagement portion contacting the axially facing surface of the adapter to prevent the second axial movement of the adapter, the axially facing surface being a visible surface as viewed along the axial direction of the threaded axle mounting opening from one axial end face of the adapter while the holding member is in the releasing position, and the adapter being rotatable within the adapter receiving bore without moving axially with respect to the bicycle fork while the holding member is in the releasing position.
