<P>PROBLEM TO BE SOLVED: To improve the durability of a link member having a bifurcated bearing while suppressing the deformation of a bifurcated bearing part in a bearing structure of a link mechanism. <P>SOLUTION: A bearing structure of a link mechanism includes: a first member 100 having a bifurcated bearing part with bifurcated bearings 120a, 120b arranged oppositely to each other in a bifurcated shape; and a second member 13 having a bearing 13a arranged between the bifurcated bearings 120a, 120b. It is configured to connect the bifurcated bearings 120a, 120b and the bearing 13a to each other by a connecting pin 26. The connecting pin 26 is configured to have a double structure in which an internal connecting pin 26a and an external connecting pin 26b are coaxially arranged at least in one of the bifurcated bearings 120a, 120b. The external connecting pin 26b is configured such that the diameter is expanded by press-fitting the internal connecting pin 26a into the inner peripheral side while the same is being inserted into the bifurcated bearings 120a, 120b of the first member 100, thereby being press-fitted into and fixed to the bifurcated bearings 120a, 120b of the first member 100. <P>COPYRIGHT: (C)2013,JPO&INPIT |
