Abstract
PURPOSE: To prevent vibration of a tone arm and to prevent change of the conductor capacity of lead wires, by providing a surface hardened layer by compressing and shaping a felt material, consisting of fibers derived from a thermoplastic resin as main fibers, and by forming slits having the surface hardened layer in the direction of circumference face axis.
CONSTITUTION: Lead wire holder 10 uses thermoplastic resin fibers as main fibers and is formed by a felt material, and most of them are arranged along the longitudinal direction of the holder, and the surface holds the form due to a surface hardened layer melted slightly. Slits 11 where lead wires 3 are stored are formed along the circumference face axis direction with a depth in the radial direction, and the surface hardened layer is formed on the wall and the bottom of the slits 11. Since slits 11 are inserted into tone arm 1 under the state where lead wires 3 are stored in slits 11 of holder 10 obtained in this manner, the distance between twisted lead wires is not changed in tone arm 1 in respect to lead wires 3, and original sound can be reproduced faithfully, and resonance of the tone arm can be prevented.
