To improve the durability of a link member having a bifurcated bearing by suppressing the deformation of a bifurcated bearing, in a bearing structure of a link mechanism.
This bearing structure of the link mechanism has a first member 100 having the bifurcated bearing of oppositely arranging bearings 120a and 120b in a bifurcated shape, and a second member 13 having a bearing 13a arranged between the bifurcated bearings 120a and 120b, and is provided for connecting the bifurcated bearings 120a and 120b and the bearing 13a by a connecting pin 26. The connecting pin 26 is formed as a double structure of coaxially arranging an inside connecting pin 26a and an outside connecting pin 26b in one of at least the bearings 120a and 120b. The outside connecting pin 26b is brought into a state of being pressed in and fixed to the bifurcated bearings 120a and 120b of the first member 100 by expanding a diameter by pressing the inside connecting pin 26a at the inner peripheral side in a state of being inserted into the bearings 120a and 120b of the first member 100.
