PROBLEM TO BE SOLVED: To provide a slide bearing which can be favorably assembled into a light distribution variable headlight device.SOLUTION: A method for manufacturing a sintered-metal slide bearing (sintered bearing) 10 for rotatably supporting a shaft to be supported attached to a light distribution variable headlight device 1 in no oil impregnated state includes: a raw material powder manufacturing process for manufacturing raw material powder which contains Cu powder as a main raw material, and Sn powder as a filler with a mixture ratio occupied in raw material powder as 7 to 11wt%, and does not contain Fe powder; a compression molding process for acquiring a green compact by performing compression molding of the raw material powder; a sintering process for acquiring a sintered body having a metallographic structure which is formed by allowing Cu powder to undergoes sintering bonding to each other by heating the green compact within the temperature range of 700 to 800°C and by dispersing Sn in Cu; and a correction process for finishing the sintered body in the shape of completed product by applying correction processing to the sintered body.SELECTED DRAWING: Figure 3 |
