設けたことを特徴とするリクライニング装置。 A base plate and an arm plate that are rotatably supported on the same axis and have internal teeth in opposing circular holes; a plurality of planetary gears that have teeth that mesh with the internal teeth of each of these plates; A rotating shaft of both plates having a control gear that meshes with the teeth of the planetary gear, and a holding body that is fitted onto the rotating shaft and holds each of the planetary gears at a predetermined orbital position. This holding body is formed by dividing it into a plurality of parts so that the parts holding each planetary gear face in the radial direction, and the parts holding these divided holding bodies face toward one side in the axial direction to have a small diameter. What is claimed is: 1. A reclining device, characterized in that the reclining device is formed in a tapered surface shape and includes a biasing means for biasing the rotating shaft toward a smaller diameter portion thereof.
