A bearing device for uniformly distributing lubricating oil between first and second bushing sliding surfaces and a connection pin is provided. The connection pin is inserted into the first bushing that is inserted into a boss member. The second bushings are inserted into a pair of bracket members. An oil storage portion is formed at a middle part of the connection pin, and is communicated to an oil feed channel that feeds lubricating oil from the outside. First sealing members and second sealing members are disposed in the first bushing and the second bushings, respectively. A pair of first channels and a second channel are formed inside the connection pin. The first channels are opened in locations in proximity to the first sealing members. The second channel is communicated to this first channel and the oil storage chamber.
