ABSTRACT:
A bearing device includes a bush and a pin inserted into the bush, whereby an outer peripheral face of the pin and an inner peripheral face of the bush contact each other. At least two oil reservoirs are formed on the outer peripheral face of the pin are and elongated along the length of the pin. The interval between the reservoirs is such that an angular range centered on the pin axial center between the first reservoir and the last reservoir is not more than a center angle of 40 degrees centered on the pin axial center. At least one of the reservoirs is configured by a plurality of punctate concave portions.
