Abstract
A V-spring member () for use in a driving system for a personal care appliance has regions () at the ends of the spring which are large enough to support a contact with an end clamping assembly, the spring member including a cross-piece () extending between the longitudinal edges of the spring at the end regions, such that the ends of the spring member define a closed line. End clamping assemblies () provided for such a V-spring member include a body portion () having a lower support portion () on which the V-spring is supported and a mating clamping member () positioned in registry with the support portion on top of the V-spring. The support portion and the clamping member include peripheral edges () which have a curved cross-sectional configuration, and which are in registry, making contact with the spring member in the end regions in such a manner as to reduce stress concentrations in the end regions of the spring, thereby reducing fretting fatigue and fretting damage in the spring.
