Abstract: A hollow stabilizer disposed in a vehicle suspension mechanism part comprises a torsion part (20); a bent part (21, 22) continuous with the torsion part (20); and an arm part (23, 24) continuous with the bent part (21, 22), and including, when a center of bending inside is 0° and a center of bending outside is 180° in a cross section in a pipe radial direction of the bent part (21, 22), eight regions (S1 to S8) defined in a circumferential direction of the cross section.

Abstract: A hollow stabilizer (10) includes a curved part (21) having eight regions (S1 to S8) defined in a circumferential direction in a cross section taken in a pipe radial direction. A first region (S1) includes a 90° first part (No. 1) when the center of the inside of the curve is taken to be at 0° and the center of the outside of the curve is taken to be at 180°. A third region (S3) includes a 0° third part (No. 3). A fifth region (S5) includes a 270° fifth part (No. 5). A seventh region (S7) includes a 180° seventh part (No. 7). The radii of curvature (R3, R7) of the respective outer surfaces of the third part (No. 3) and the seventh part (No. 7) are larger and the radii of curvature (R2, R6) of the respective outer surfaces of the second part (No. 2) and the sixth part (No. 6) are smaller than the radii of curvature (R4, R5) of the respective outer surfaces of the fourth part (No. 4) and the fifth part (No. 5).
