Abstract
A personal care appliance which includes at least one flexible spring. The flexible spring having an grounded section with an outer surface and an inner surface, a rotational member arranged radially within the grounded section, wherein the rotational member is arranged to rotate within the grounded section in a first rotational direction about an imaginary rotational axis, and a compliant member having a first end and a second end, wherein the first end is operatively engaged with the inner surface of the grounded section and the second end operatively engaged with the rotational member. The compliant member has a first stiffness such that the compliant member is arranged to resist rotation of the rotational member in at least the first rotational direction.
