    Abstract: A stabilizer includes bend sections. With respect to positions in a circumferential direction of a radial cross section of each of the bend sections, a center of an inside of a bend is defined as 0°, and a center of an outside of the bend is defined as 180°. The bend sections each include a bend interior section located at 0°, a bend exterior section located at 180°, a first side section located at 90°, and a second side section located at 270°. The bend interior section has compressive residual stress from a surface to a first depth. The bend exterior section has compressive residual stress to a second depth. The first side section has compressive residual stress to a third depth. The second side section has compressive residual stress to a fourth depth.

    Abstract: A stabilizer includes a stabilizer main body, and eyes formed on both ends of the stabilizer main body. Through-holes are formed in fastening surfaces of the eyes, respectively. The stabilizer main body is covered with a main body coating film. The eye is covered with an eye coating film whose thickness is less than a thickness of the main body coating film. An inner surface of the through-hole is covered with an inner surface coating film. An incomplete coating portion is formed at a part of the inner surface of the through-hole in a circumferential direction. The incomplete coating portion is located on an extension of a straight line connecting a center of the through-hole and the center of gravity of the stabilizer main body in a side view of the stabilizer main body.
