。[Problem to be Solved by the Invention] However, such a bearing device does not pose much of a problem if the bearing has a relatively thick wall and has excellent rigidity, but it does not require flexible lubrication. In the case of flexible bush bearings with extremely thin walls, such as rolled bush bearings formed by winding a sheet into a cylindrical shape, bearing devices using the above-mentioned fixing means have various problems. cause

じる、という種々の問題がある。That is, as shown in FIGS. 14 to 17, an expanded metal with a regular mesh (for example, thickness t=0.5 mm) is used as the base material 1, and the mesh 2 and the surface of the base material 1 are lubricated. A flexible lubricating sheet 4 filled with and coated with a synthetic resin composition 3 having properties of elasticity was wound into a cylindrical shape to form a cylindrical portion 5 and an enlarged-diameter flange portion 6 integrally at one end of the cylindrical portion 5. In a bearing device using a flanged cylindrical bushing bearing 7, it is extremely difficult to form a key hole using a locking means because the bushing bearing 7 has an extremely thin wall (thickness t = approximately 0.7 mm). Even if a key holder could be formed, the bush bearing is flexible, so it would be difficult to securely hold the key in the key holder, and the key might fall off while the bearing device is in use. On the other hand, when fixing by press-fitting into the hole of the shaft mounting member, the bush bearing is flexible and has extremely low rigidity, so the press-fit itself is difficult and it is difficult to obtain a strong fixing effect. However, there are various problems in that relative rotation easily occurs between the bush bearing and the shaft mounting member during use of the bearing device.
