Abstract: A universal joint which retains a lubricant, is capable of suppressing the exudation of a lubricating component to a minimum amount and preventing the lubricant from scattering from an open portion when the lubricant is deformed by an external force, and a method for producing the universal joint. In the universal joint, a rotational torque is transmitted by engagement between a torque transmission member (6) and tracks (4, 5) provided on an outer member (2) and an inner member (3); the torque transmission member (6) rolls along the tracks (4, 5), thus moving in an axial direction; and a porous solid lubricant (10) is enclosed on a periphery of the torque transmission member (6). The porous solid lubricant (10) containing a lubricating component and a resin component is a solid made porous by foaming and hardening the resin component.

Abstract: It is an object of the present invention to provide a cage that can be used in a cryogenic-temperature environment or a vacuum without providing the cage with a complicated construction and without performing special treatment and a bearing using the cage. A cage made of resin has an annular main body having a plurality of pocket portions radially penetrating the main body; and a plurality of pocket members, provided on the annular main body, which hold rolling elements of a rolling bearing. The main body is a molding of a first resin composition consisting of a first resin and a solid lubricant mixed therewith; and at least a rolling element-retaining surface of each of the pocket members is made of a second resin composition containing fluorocarbon resin as a main component thereof. The molding of the first resin composition has a tensile strength of not less than 30 MPa and a heat-resistant temperature of not less than 200° C. The second resin composition is a fluorocarbon resin composition.
