Claims

[Claims for Utility Model Registration] A rod having a large diameter portion with a nut body screwed onto one end and a cam hole perpendicular to the axis at the other end, the rod being fitted into the large diameter portion so as to be relatively movable in the axial direction. and a cap-shaped presser fitting having a shaft support hole corresponding to the cam hole, a support shaft portion that is inserted in communication with the shaft support hole and the cam hole, and an arm portion for rotating the support shaft portion. a lever; and an eccentric cam portion formed to be eccentric with respect to the rotational axis of the support shaft at a portion of the support shaft located in the cam hole, and the lever is fixed to the hub fixed position. and the hub release position, the eccentric cam part reciprocates in the direction of the hub axis and presses the inner surface of the cam hole, and the rod and the cap-shaped holding fitting move relative to each other in the direction of the hub axis. In the quick release device for a bicycle hub, an engaging surface with unevenness is provided on the axial inner surface of the nut body and the holding metal fitting, and a hawk end is provided at a portion facing these engaging surfaces in the axial direction. A quick release device for a bicycle hub, characterized in that it is provided with a detent means that cannot be rotated relative to the nut and has projections and depressions that engage with the projections and depressions to prevent rotation of the nut body or the presser fitting.
