徴とする多心光ロータリジヨイント。 In a multi-core optical rotary joint that connects an optical fiber on a rotating side and an optical fiber on a stationary side, a cylindrical rotating gear that rotates due to rotational input from the rotating side and has teeth formed on its outer peripheral surface; A plurality of gear mechanisms for trapezoidal prisms are disposed on the outer periphery of the stationary side of the rotating gear, each having a trapezoidal prism, and are rotationally driven by the rotating gear; It has a plurality of rod lenses arranged facing the trapezoidal prisms and coupled with optical fibers on the rotating side, and a rotating side gear mechanism that is rotationally driven by a rotating gear, and fixed on the stationary side in correspondence with each trapezoidal prism. A rod lens that faces the trapezoidal prism and is connected to an optical fiber on the rotating side is provided to optically oppose the rod lens via the trapezoidal prism, and an optical fiber is connected to each rod lens on the stationary side. A multi-core optical rotary joint characterized in that the rotation ratio between the rotation speed of the rod lens of the side gear mechanism and the rotation speed of the trapezoidal prism of the trapezoidal prism gear mechanism is set to 1/2.
