PROBLEM TO BE SOLVED: To provide a vehicle knuckle manufacturing method that ensures satisfactory castability that achieves both casting of a knuckle that is able to restrict vibration transmission from a front wheel to a vehicle body and improvement in manufacturing efficiency, and to provide a knuckle.SOLUTION: A manufacturing method is for a knuckle 50 having: a bearing mounting part 51 on which a hub bearing is mounted; a damper sandwiching part 541 griping a damper; and a damper mounting arm 542 connecting the bearing mounting part 51 and the damper sandwiching part 541. The manufacturing method includes integrally casting, by use of one ring 130: a cylindrical opening S1, which is an inner space of the damper sandwiching part 541; a continuous hollow opening S2 formed in an inner space in a hollow part 544 of the damper mounting part 542 extending from the damper sandwiching part 541 in a closed cross-sectional form and also formed in the damper sandwiching part 541; and an arm opening S3 surrounded by a front arm part 545 and rear arm part 546 of the damper mounting arm part 542 extended from the hollow part 544.SELECTED DRAWING: Figure 11
