<p>The present invention aims to minimize the deformation during manufacturing (molding) or use, to secure sufficient stability and reliability of a bearing, to reduce the cost of parts and manufacturing, to secure mechanical strength, to decrease the weight of the product, to enhance the ease in manufacturing, and reduce the material costs. The bearing device of the present invention, in a bearing device having a bearing unit (4, 4) installed in the casing (3) for supporting a rotating shaft (2) to freely rotate, is molded to be one body with the casing (3) by a synthetic resin material (R) for making the bearing unit (4) into the shape of a ring having a certain thickness (Dt) toward the direction of the axis (Fs) and a certain ring thickness (Dr) toward the direction of the diameter (Fd). The bearing device of the present invention is placed on the end surface of the bearing unit (4) along the circumference (Fc) with a certain interval (La). In addition, a plurality of tolerance absorbing concave units (5...) selecting a floor unit (5d) with a certain thickness (Lb) is formed, thereby selecting the place between the tolerance absorbing concave units (5) and the inner circumferential surface (4s) of the bearing unit (4) with a certain thickness (Lc).</p> |
