PURPOSE:To prevent heat generation due to slippage and improve transmission capacity by forming the contact surface of a friction wheel with a molded item in which 0.1-10wt% of silicone oil is added and mixed to an elastomer having affinity for said silicone oil. CONSTITUTION:The friction surfaces of friction wheels A, B are formed with an elastomer. The elastomer is formed with an item in which 0.1-10wt% of silicone oil such as polysiloxane, etc. is valcanized to an elastomer material such as urethane, etc. having affinity for silicone oil. Its surface friction coefficient can be adjusted by the adding quantity of the silicone oil, enabling the friction coefficient on the contact surface to be adjusted without varying the hardness and elasticity modules of the elastomer. Accordingly, a friction wheel with high transmission capacity can be obtained without increasing contact pressure while preventing heat generation, etc. due to surface friction.
