In a steering wheel comprising a rim portion having a core metal and a covering portion 5 covering the core metal, and a mat material 6 provided between an outer surface material 9 and the covering portion 5 of the rim portion and having a conductive portion 7 on a part facing the outer surface material 9, and the outer surface material 9 has a joined portion 91 formed in a direction intersecting a circumferential direction of the rim portion, the covering portion 5 is provided with a groove 51 in which the joined portion 91 and a part of the mat material 6 are housed, and between the outer surface material 9 and the conductive portion 7, a sliding member 8 is interposed at least in a vicinity of the joined portion 91.

Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catechol-amine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.

A bearing laminate can include a metal support layer, a foam layer overlying the metal support layer, the foam layer including a polymeric foam; and a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix. Bearing articles made from the bearing laminate can have exceptional damping properties, such as a high damping ratio combined with a low dynamic stiffness.
