Bicycle wheel securing device

A bicycle wheel securing device comprising:

• a shaft having a first shaft end, a second shaft end, and a longitudinal center axis, the shaft extending between the first shaft end and the second shaft end along the longitudinal center axis;
• an axial abutment structure disposed at the first shaft end;
• a bicycle-body engaging structure disposed at the second shaft end;
• a manual actuator operatively connected to the axial abutment structure to bias the axial abutment structure against a first wheel attachment part of a bicycle body in response to operation of the manual actuator in a securing state where the bicycle-body engaging structure is engaged with a second wheel attachment part of the bicycle body;
• and
• a shaft-end retaining structure at least partly disposed at the second shaft end to retain the second shaft end in the first wheel attachment part in a maintenance state where the second shaft end is positioned in the first wheel attachment part of the bicycle body,
• wherein the shaft-end retaining structure comprises a first retaining structure and a second retaining structure, the first retaining structure is disposed at the first wheel attachment part, and the second retaining structure is at least partly disposed at the second shaft end to be engaged with the first retaining structure in the maintenance state,
• wherein a middle of the shaft has a first outermost diameter and the second retaining structure has a second outermost diameter, the second outermost diameter does not exceed the first outermost diameter,
• wherein the shaft-end retaining structure includes an elastic retaining member, and
• wherein the elastic retaining member comprises a snap ring.
