PROBLEM TO BE SOLVED: To provide a pin bearing structure that can resist horizontal force in the axial direction of a pin. SOLUTION: The pin bearing structure holds the horizontally extended pin 3 between a lower shoe 1 fixed to a lower structure and an upper shoe 2 fixed to an upper structure, and allows the relative rotation of the lower shoe 1 and upper show 2 around a pin axis O. The lower shoe 2 is provided with a pair of stoppers 15 respectively projected upward and arranged with a space in the direction of the pin axis O, and the upper shoe 2 is fitted between the pair of stoppers 15.
