Cam follower and method for producing cam follower

A cam follower comprising:

• an outer ring which has an outer track surface on an inner circumference of the outer ring;
• a cam follower stud including
• a bearing support portion formed with an inner track surface opposed to the outer track surface,
• a flange portion abutting on one side of the inner track surface,
• a side plate fitting portion abutting on another side of the inner track surface, and
• a mounting shaft portion abutting on the side plate fitting portion, the side plate fitting portion being between the mounting shaft portion and the other side of the inner track surface,
• rolling elements arranged between the outer track surface and the inner track surface;
• and
• a side plate pressed into the side plate fitting portion for association with the flange portion in limiting axial movement of the outer ring and the rolling elements,
• wherein a relief is formed on a stepped portion between the flange portion and the bearing support portion, the relief having a forged surface and being recessed into the flange portion from the bearing support portion,
• the cam follower stud being formed so as to have a non-severed fiber flow formed continuously along a surface of the cam follower stud from the flange portion to the bearing support portion, where the fiber flow is densified and makes a curve along a shape of the recess of the relief, and continues toward the bearing support portion while becoming wider.
