PROBLEM TO BE SOLVED: To provide a slide bearing which can be favorably assembled into a light distribution variable headlight device.SOLUTION: A sintered-metal slide bearing (sintered bearing) 10 is formed by sintering a green compact of raw material powder with metal powder as a main raw material, and rotatably supports a shaft (shaft part 4a and a shaft part 5a) which is attached and supported to a light distribution variable headlight device 1. As raw material powder for manufacturing the sintered bearing 10, Cu powder is used as the main raw material, and Sn powder, C powder and Ni powder are blended as fillers to the Cu powder. The raw material powder does not contain Fe powder at all. Blending ratios of the Sn powder, the C powder and the Ni powder occupied by the whole raw material powder are 7 to 11 wt%, 3 to 7 wt%, and 4 to 6 wt%, respectively. |
