Title:
VEHICLE STABILIZER, MACHINING DEVICE FOR EYE SECTION OF STABILIZER, AND MACHINING METHOD FOR EYE SECTION
Document Type and Number:
WIPO Patent Application WO/2017/068994
Kind Code:
A1
Abstract:
Provided is a vehicle stabilizer in which an annular reference surface (52) is formed around a through hole (45) in an eye section (21). A leading end-side curved section (55) is formed on the outer side of the annular reference surface (52) at a first corner (C1) at which a first flat surface (41) and a leading end surface (50) intersect. The thickness of the leading end-side curved section (55) decreases across the length (H1) thereof from the first flat surface (41) toward the leading end surface (50). A hole-side curved section (60) in which the thickness decreases as proximity to the inner surface (46) of the through hole (45) increases is formed on the inner side of the annular reference surface (52) at a second corner (C2) at which the first flat surface (41) and the inner surface (46) intersect. The length of the hole-side curved section (60) is smaller than the length (H1) of the leading end-side curved section (55). The hole-side curved section (60) is curved so as to have a larger curvature (a smaller radius of curvature) than the leading end-side curved section (55).
