Title:
RESIN ROTATIONAL BODY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/002014
Kind Code:
A1
Abstract:
Disclosed is a resin rotational body (1) configured by a ring-shaped resin ring (2), and a metal bush (3) fitted to the inner peripheral surface (2a) of the resin ring, wherein the metal bush is provided on its outer peripheral surface with a projection (3a) functioning as a rotation preventing means for connecting the resin ring and the metal bush while preventing mutual rotation. The resin ring is formed by thermal-compressing a blank body which is formed by laminating a plurality of resin sheets produced by a paper making process in the axial direction, and which is formed so that the diameter of its inner peripheral surface becomes substantially identical to the diameter of the outer peripheral surface of the metal bush, and the metal bush is integrally connected to the resin ring by press fitting the bush to the inner peripheral surface of the blank body along the axial direction. The projection of the metal bush is provided at a position forward biased in the press-fitting direction of the metal bush from the center in the axial direction of the metal bush. Provided is a resin rotational body which can be produced by simple steps, and can prevent the occurrence of dropping of the resin ring from the metal bush.
