First Claim
1. A bearing device for a manual beauty and health roller having a grippable main unit and a roller arranged at an end portion of the grippable main unit, the bearing device rotatably supporting the roller on a support shaft on said end portion of the grippable main unit,the bearing device characterized in comprising:
- a radial bearing into which the support shaft is fitted, the radial bearing rotatably supporting the roller on the support shaft;
a thrust bearing arranged toward one end face of the radial bearing, a preload-applying member interposed between the radial bearing and the thrust bearing, said radial bearing being adapted to rotate synchronously with said roller when said roller is pressed against bare skin and said roller is caused to rotate,wherein the preload-applying member is in contact with the thrust bearing and each of the radial bearing and the thrust bearing is a slider bearing obtained by being molded from a resin composition andwherein the entire preload-applying member is a single piece elastic ring that is elastically deformed and said elastically deformed ring is interposed between the radial bearing and the thrust bearing,characterized in that the elastic ring comprises a cylindrical portion fitted to a sleeve portion of the radial bearing, and a flared portion in contact with the thrust bearing.
