Patent ID: 7628416

Claim:
A bicycle wheel securing structure comprising: a shaft member having a first end portion and a second end portion with a longitudinal center axis extending therebetween; a head member coupled to the shaft member at the second end portion of the shaft member; a lever member operatively mounted between the shaft member and the head member to move the shaft member in an axial direction of the shaft member relative to the head member in response to movement of the lever member; a radial expansion structure disposed at the second end portion of the shaft member, the radial expansion structure including an expansion member and the second end portion of the shaft member, the expansion member having a first inclined surface and the second end portion of the shaft member having a second inclined surface that cooperates with the first inclined surface of the expansion member to radially expand an outer diameter of the radial expansion structure in response to the movement of the lever member from a release position to an attachment position, the first and second inclined surfaces being inclined relative to the longitudinal center axis; and an adjustment member axially adjustably coupled to the head member to move on the head member in the axial direction of the shaft member with respect to the head member, an axial position of the expansion member of the radial expansion structure being adjusted with respect to the head member in the axial direction of the shaft member in response to an axial adjustment of the adjustment member with respect to the head member, the shaft member moving with respect to the adjustment member in the axial direction of the shaft member in response to the movement of the lever member.
