PROBLEM TO BE SOLVED: To provide a bearing device in which pre-load and a clearance can be properly adjusted with a spacer, and in which drag turning of the spacer can be suppressed, and thereby generation of noise can be suppressed.SOLUTION: The bearing device is provided that comprises: a bearing 6; a C-shaped spacer 83 which abuts on a one-side axial end face of the ball bearing 6 and has an axially extending through-hole; an axially extending axial extension groove 36 formed in an outer circumferential surface of the ball bearing 6; a one-body pin 50 which penetrates the through-hole of the C-shaped space 83, and the one-side projecting portion 25 of which is accommodated in the axial extension portion 36. The pin 50 has a columnar metallic body portion, and a soft metal film covering an outer circumferential surface of the body portion, and composed of soft metal having hardness lower than that of the body portion.SELECTED DRAWING: Figure 9 |
