A bicycle rim includes a plurality of elongate slots each of which is composed of a first diameter portion and a second diameter portion which is smaller than the first diameter portion. A tube having threaded outer periphery is inserted in each elongate slot and a core piece is inserted through a passage in the tube. The tube has a flange engaged with an inside of the rim and a cover member covering each elongate slot has a threaded hole for being threadedly connected to the threaded outer periphery of the tube. A protrusion extends from a side of the cover member so as to be engaged with the first diameter portion while the tube is shifted to the second diameter portion. A spoke is inserted in the core piece and threadedly connected to a threaded inner periphery of the core piece.
