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.
