とする軸受構造。 At a pin joint portion where a boss member is connected to the bracket member via a pin and the boss member is rotatably connected to the pin, opposing contact surfaces of the two members, the bracket member and the boss member; A sealing member is provided all around the outer circumference of the gap, and a clamping ring member having a split portion is further fitted along the outer circumference of the sealing member, while the end face of the bracket member is in contact with the sealing member. A cutout groove is formed in a part of the boss member to communicate the gap between the contact surfaces of the two members and the outside of the bracket member, so that when the pin connection part is greased, excess grease is removed after the grease reservoir inside the boss member is filled. A bearing structure characterized in that it is configured to be able to overflow to the outside through a gap between opposing surfaces of the two members, a notch groove of the bracket member, and a split portion of the clamping ring member.
