The invention discloses a front airplane wheel for an amphibious airplane, and particularly relates to the field of airplane wheel braking. Comprising an outer half hub and an inner half hub which are connected to a nose landing gear axle in a sleeving mode. Wherein an outer side bearing and an outer oil retainer are sequentially arranged in an outer bearing chamber of the outer half hub from inside to outside, and the outer edge of the outer oil retainer is in close contact with the side wall of the outer bearing chamber; a protective cover is connected to the outer half hub and is positioned on the outer side of the outer bearing chamber; an inner side bearing and an inner oil baffle mechanism are sequentially arranged in an inner bearing chamber of the inner half hub from inside to outside; wherein the inner oil baffle mechanism comprises an oil baffle ring bracket which is tightly sleeved on the axle of the nose landing gear, and the oil baffle ring bracket is positioned in the inner bearing chamber and is positioned on the outer side of the inner side bearing; the inner oil retainer is located between the oil retainer support and the inner half hub and makes close contact with the oil retainer support and the inner half hub. And liquid such as seawater can be prevented from entering the front airplane wheel under the action of pressure.
