To provide a steering knuckle capable of inhibiting impairment of a border between an attachment part and an arm.SOLUTION: A steering knuckle 1 includes a body 2 to be attached to an axle, an attachment part 3 having a shaft hole 31 into which a shaft member penetrates, and an arm 4 linking the body 2 and attachment part 3. The attachment part 3 has a planar attachment bearing surface 32 in which the shaft hole 31 opens. The arm 4 has a cross surface 41 that adjoins and crosses the attachment bearing surface 32. A borderline 5 between the attachment bearing surface 32 and cross surface 41 has plural specific points 6, at which the distance to the center of the shaft hole 31 is the shortest, only in the middle of the borderline 5.SELECTED DRAWING: Figure 2
