摘要： A bicycle crank fixing structure is arranged to fix a left crank with a mounting bore and a slit extending radially from the mounting bore to a crank axle. The mounting bore is non-rotatably coupled to the crank axle. The slit is provided with two mounting bolts that perpendicularly intersect to adjust a width of the slit to fasten the crank to the crank axle. The crank axle has a retaining hole formed on the outer circumferential surface thereof which faces the slit of the crank. A retaining member with a retaining projection is disposed in the slit such that the retaining member rotates by rotation of the mounting bolt. The retaining projection of the retaining member is retained in the retaining hole formed on the crank axle to prevent the crank from detaching from the crank axle even when a fastening bolt is loosened.

摘要： A bicycle crank arm assembly for a bicycle is designed for mounting a sprocket thereto. The crank arm has a centrally located hub portion, a crank portion extending radially outwardly from the hub portion and at least three fastening fingers extending radially outwardly from the hub portion. The fastening fingers are designed to have substantially the same stiffness at their free ends. This can be accomplished in a variety of ways such as change the cross-section of the fastening fingers adjacent the crank portion or changing the shape of the sprocket mounting portions of the fastening fingers. Also, in certain embodiments, the fastening fingers adjacent the crank portion are constructed such that their rear surfaces lie in the same plane as the rear surface of the crank portion adjacent thereto, or in a lower plane.
