▎ 摘　　要

NOVELTY - The component (6) has a composite material that is provided with a matrix and a multitude of a nanowire is distributed in the matrix. The nanowires are juxtaposed. The matrix is provided with a material for filling an interstices between the nanowires to join to each other. Each nanowire is provided for forming a solid one-piece tube. The nanowires are mounted parallel to an axis perpendicular to the main plane of component. The nanowires are provided with a diameter (D) within a range from 2 to 50 nm, and within a range from 3 to 15 nm, or from 5 to 10 nm. The component is a spiral balance spring (8). USE - Flexible timepiece component for barrel of horological movement (claimed). ADVANTAGE - The friction between two mobiles are reduced, and the addition of a standard lubricant degrades friction and increases wear in an anti-shock component. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a balance provided with a spiral spring of a mechanical oscillator mechanism. Flexible timepiece component (6) Spiral balance spring (8) Circular ring (9) Rectilinear arm (11) Fixed portion (17)
