Abstract
A stabilizer is a stabilizer including: a main body cylinder portion which is elastically deformable and a pair of connection plate portions respectively connected to a pair of left and right suspension devices, wherein the connection plate portion includes a pair of base material portions located on both sides in the connection plate portion in a plate thickness direction T and an alloy oxide region which is disposed between the pair of base material portions and in which alloy oxides are scattered, and wherein crystal grains constituting the pair of base material portions straddle the alloy oxide region in the plate thickness direction and the pair of base material portions are joined.
Claims6
A stabilizer comprising:
- a main body cylinder portion which is elastically deformable;
- and
- a pair of connection plate portions respectively connected to a pair of left and right suspension devices,
- wherein each connection plate portion of the pair of connection plate portions includes a pair of base material portions located on both sides in the connection plate portion in a plate thickness direction and an alloy oxide region which is disposed between the pair of base material portions and in which alloy oxides are scattered,
- wherein crystal grains constituting the pair of base material portions straddle the alloy oxide region in the plate thickness direction and the pair of base material portions are joined,
- wherein the connection plate portion is made of a Fe alloy containing an easily oxidizable element that is more easily oxidized than Fe, and
- wherein the alloy oxides are made by combining oxygen, which is obtained by reducing Fe oxides present on an inner peripheral surface of the base material portions prior to joining, and the easily oxidizable element.
