Abstract
To provide a bearing device, which can be easily processed, and whereby, its durability is capable of being improved and a load (tractional force) can be remarkably increased till the burn-in occurs and a pin for the bearing device. The bearing device is provided with a bush and a pin to be inserted in this bush. When an external force is acting in a certain direction, the bush and the pin are relatively rocked, and a slidable range H is formed, in which an outer peripheral face of the pin and an inner peripheral face of the bush partially and slidably contact with each other. An oil reservoir is provided at the side of the pin in order to prevent a no-lubrication portion, to which no lubrication oil is supplied, from being formed in the slidable range H.
