Title:

BUSH FOR STABILIZER, FASTENING TOOL, AND FASTENING METHOD

Document Type and Number:

WIPO Patent Application WO/2014/065186

Kind Code:

A1

Abstract:

Provided is a technique for fastening a bush to a bar of a stabilizer, in which the necessary fastening strength can be obtained by equalizing surface pressure in a fastening surface (inner peripheral surface) of a hole section of the bush. In a hole section (100A) of a bush (100), a first arc section (101) is formed on the side opposite an opening section of a U-shaped part (41) of a bracket (40) (FIG. 3(B)) used during fastening, and a second arc section (102) is formed on the side of the opening section of the U-shaped part (41). The first arc section (101) and the second arc section (102) are arc sections of, e.g., arcuate or substantially arcuate shape, or ellipsoidal arc sections of, e.g., ellipsoidally arcuate or substantially ellipsoidally arcuate shape. In the hole section (100A), the center (O1) of the first arc section (101) and the center (O2) of the second arc section (102) are set apart. The curvature radius (r2) of the second arc section (102) is set smaller than the curvature radius (r1) of the first arc section (101). The hole section (100A) preferably has, e.g., an egg shape as shown in FIG. 6.
