Abstract
Official abstract text for this publication.
A stabilizer includes a main body cylinder portion which is elastically deformable; and a pair of connection portions respectively connected to a pair of left and right suspension devices. Each of the pair of connection portions is provided with a fixed shaft portion which is solid and fixed to the main body cylinder portion. The fixed shaft portion includes a fitting portion fitted into the main body cylinder portion and a large diameter portion connecting the fitting portion and a connection portion of the pair of connection portions and formed to have a diameter larger than that of the fitting portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A stabilizer comprising: a main body cylinder portion which is elastically deformable; and a pair of connection portions respectively connected to a pair of left and right suspension devices, wherein each of the pair of connection portions is provided with a fixed shaft portion which is solid and fixed to the main body cylinder portion, wherein the fixed shaft portion includes a fitting portion fitted into the main body cylinder portion and a large diameter portion connecting the fitting portion and a connection portion of the pair of connection portions and formed to have a diameter larger than that of the fitting portion, and wherein the stabilizer is provided with a first welded portion joining an opening end edge of the main body cylinder portion and the large diameter portion and continuously extending over the entire length thereof in a circumferential direction around a center axis of the main body cylinder portion and a second welded portion joining an inner peripheral surface of the main body cylinder portion and an outer peripheral surface of the fitting portion. 2. The stabilizer according to claim 1 , wherein the first welded portion and the second welded portion are connected to each other and continuously extend. 3. The stabilizer according to claim 2 , wherein the second welded portion continuously extends over the entire length thereof in the circumferential direction, wherein an intermediate welded portion is provided between the first welded portion and the second welded portion to join the inner peripheral surface of the main body cylinder portion and the outer peripheral surface of the fitting portion, and wherein the first welded portion, the second welded portion, and the intermediate welded portion are connected to each other and extend in an endless shape. 4. The stabilizer according to claim 3 , wherein the intermediate welded portion extends in the circumferential direction over an angle range exceeding 360° around the center axis of the main body cylinder portion.
