Title:
WHEEL BEARING DEVICE WITH BRAKE ROTOR
Document Type and Number:
Japanese Patent JP2014180984
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wheel bearing device with a brake rotor which avoids load concentration, and improves the strength of the brake rotor.SOLUTION: On a side surface on a flange portion 23 side of a brake rotor, recessed portions 11b are formed at positions corresponding to edges 23b. A flat surface 11e closely contacted with the side surface of the flange portion 23 is formed between a pair of the recessed portions 11b. The width of the recessed portion 11b is made to be smaller than the width of the flange portion 23. A curved surface 11d is formed on the flat surface 11e side on the side surface of the flange portion 23 side of the brake rotor so as to form a part of the recessed portion 11b. On a boarder line S of the curved surface 11d and the flat surface 11e, the curved surface 11d is formed so as to make a tangent of the curved surface 11d pass through the flat surface 11e.
