締結して車軸う把持する。In order to achieve the above object, the front fork axle mounting device of the present invention has a combination of a fixed boulder and a cap rotatably attached to the fixed holder with a pin at the lower end of the front fork. The fixed boulder and the cap are each formed into a half-shape, and an axle mounting groove is provided in the abutting part, so that the ends of the fixed holder and the cap are connected to each other. In an axle mounting device that holds an axle by tightening bolts and nuts, the cap is formed in a shape that grips the axle from below, and the base of the cap is designed to hold the axle by the pressing force of the axle when the axle is inserted. The cap rotates and closes with its own blade, and when the cap is opened, the axle is ejected by the pressing force as the cap rotates.[Function] Inserts the axle. When the axle is inserted and the axle presses the protrusion, the cap automatically rotates and closes using the pin as a fulcrum. Then, the axle is fitted into the axle mounting groove so that the abutting portions of the fixed holder and the cap come into contact with each other, and bolts and nuts disposed at the ends of the fixed holder and the cap are fastened to grip the axle.
