ABSTRACT:
A bearing device includes a slidemember made of porous-sintered-metal for slidably supporting a rotational shaft, and a holding member made of the same porous-sintered-metal and holding the slide member. The two members are constructed of the same material, and yet the density of the slide member is greater than that of the holding member so that lubricating oil is supplied continuously from the holding member to the slide member due to the capillary phenomenon. The bearing device constructed as above prevents the lubricating oil from flowing out, improves abrasion-resistance, and thereby extends the service life. Further, this construction allows the bearing device to be smaller and thinner.
