To produce a mixture of a lubricating oil and a lubricating oil carrier, which is not aggregated to form a mass, and to provide an oleo bearing with stable quality, which is free from the generation of poor dispersibility in the step of mixing with a synthetic resin powder and a reinforcement filling agent.

The oleo-resin composition contains the lubricating oil, the lubricating oil carrier, the reinforcement filling agent, and a self-lubricating resin. The composition contains a 10 to 15 vol.% styrene-butadiene-radial tereblock copolymer as the lubricating oil carrier in the entire oleo-resin composition, wherein the weight ratio of styrene to butadiene ranging from 25/75 to 35/65, MFR(G)[200°C, 5 kg] is 1 g/10 min or less, and the viscosity of a 25 wt.% toluene solution is 20,000 cps or more. The composition contains the lubricating oil and the lubricating oil carrier at a volume ratio of 1.5 to 2 : 1.
