<p>PURPOSE:To obtain a number of signal passes simultaneously with a simple structure by providing plural signal wire slip rings in a mutually insulated condition in the same track while providing a common slip ring having an arc-shape with the same center angle as that of each of said slip rings. CONSTITUTION:On the top face of a slip ring substrate formed with a glass fiber reinforced epoxy resin, give arc-shaped slip rings 2a for first signal wires are print wired while being mutually insulated on a circular track R close to its outer periphery, and a slip ring 25 for a common wire having an arc shape with the same center angle as that of each of the first signal wire slip rings 2a is provided on the inside of the track R and, when a steering wheel is in a neutral position, a sliding piece 18 is positioned on its center part. At the time of steering within a defined angle theta, electrification can be carried out through the first signal wire slip rings 2a and the common wire slip ring 25. Thereby, a number of signal wire passes can be simultaneously formed with a simple structure.</p> |
