Abstract
In a rotary joint A including an electric signal slip ring 31 for passing different electric signals between a stator 1 and a rotor 6, for the purpose of stable transmission of electric signals in the electric signal slip ring 31, stationary side electrode stacks 38a and 38b are provided individually by stacking each pair of axially adjacent two 36b to 36e of six ring-plate-shaped stationary side electrodes 36a to 36f arranged concentrically with the axis of the stator 1 and aligned axially with each other together with one of stationary side insulating seats 37a and 37b interposed between the pair of axially faced stationary side electrodes, rotating side electrode stacks 42a to 42c are provided individually by stacking each pair of axially adjacent two 40a to 40f of six ring-plate-shaped rotating side electrodes 40a to 40f arranged concentrically with the axis of the rotor 6 and aligned axially with each other together with one of rotating side insulating seats 41a and 41c interposed between the pair of axially faced rotating side electrodes, a group of the stationary side electrode stacks 38a and 38b and another group of the rotating side electrode stacks 42a to 42c are arranged…
