Title:
ARC SPRING AND DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/146659
Kind Code:
A1
Abstract:
A spring housing space (3) for housing an arc spring (1) has a prescribed curvature radius (R1) and attachment angle (θ0). By bending the arc spring (1) to house it within the spring housing space (3), the curvature radius (Ra) is smaller, and the attachment angle (θ0) of the arc spring (1) exceeds the free angle (θa). Negative torsional stress is thereby imparted to the wire material constituting the inside peripheral part of the arc spring (2).
