Fastening structure

Abstract

To obtain a fastening structure capable of improving holding force of holding two fastened members.SOLUTION: Bolts 30, 32 are inserted into first bolt holes 18X, 18Y and second bolt holes 26X, 26Y to fasten caliper mounting parts 18A, 18B of a knuckle 18 to arm parts 26A, 26B of a caliper bracket 26. Bolt insertion parts 40, 42, each composed of the first bolt holes 18X, 18Y and the second bolt holes 26X, 26Y, are provided in pairs. Each of the bolt insertion parts 40, 42 is formed so as to penetrate inclined contact surfaces 18C, 26C, 18D, 26D, which are contact surfaces between the knuckle 18 and the caliper bracket 26 and are inclined relative to a direction perpendicular to axial lines of the bolts 30, 32. Each of the inclined contact surfaces 18C, 26C, 18D, 26D is inclined toward the knuckle 18 side toward a center side between the paired bolt insertion parts 40, 42.SELECTED DRAWING: Figure 2
