According to the present invention, at the position of both side surfaces 13 and 14 of the rim 10, a crest 20 having a wavy or saw-tooth shape with a cross section is formed. When traveling on a wet and slippery road, mud and water droplets are introduced into the concave portion 21 between the stripes 20 and discharged, so that the normal operation of the brake 30 is not affected.
【０００８】 上述のリム１０及び条紋２０はアルミ押し型で一体成形方式で同時に製造され 、機械（旋盤）による二次加工の煩わしさがなく、また製造コストを下げること ができる。The rim 10 and the stripe 20 described above are simultaneously manufactured in an integral molding system using an aluminum stamping die, so that there is no need for troublesome secondary processing by a machine (lathe) and the manufacturing cost can be reduced.

Among them, wave-shaped stripes 20 having high and low sides are formed on the side surfaces 13 and 14 of the aluminum alloy rim 10, and the stripes 20 are formed by directly extruding the aluminum alloy, and the side surfaces of the rim 10 are formed. No special CNC machining is required for the parts 13 and 14, and the wavy stripes 20 having a difference in height after direct extrusion have a function of increasing the frictional force during braking.
【００１０】 リム１０の側面１３、１４に直接押し出し成形された高低差のある波状の条紋 ２０中の低い条紋２２はリム１０の側面１３、１４が、泥道或いは雪道、或いは 湿った滑り易い道を走行する時にかかる泥や水滴を二つの低い条紋２２間の凹部 ２１内に導入する。高い条紋２３は、ブレーキ３０と接触する。こうして高低差 のある条紋２０によりブレーキ３０が汚泥や水滴のついたリム１０の側面１３、 １４に接触する時の空滑りの現象が防止される。[0010] The lower ridges 22 in the wavy ridges 20, which are directly extruded and formed on the side surfaces 13, 14 of the rim 10, are formed when the side surfaces 13, 14 of the rim 10 are covered with muddy or snowy roads or wet sliding. The mud and water droplets that occur when traveling on an easy road are introduced into the recess 21 between the two low stripes 22. The high stripes 23 come into contact with the brake 30.
