くしたことを特長とする軸受部構造。 A pin is inserted through a boss with two left and right bushes and a dust seal on the outside of the boss, and a fixed side bracket is inserted into the fixed side bracket so that they can rotate freely. In a bearing structure in which grease is supplied from the outer periphery of the boss via a grease reservoir formed by the inner end surface of the bush, the inner diameter of the boss, and the outer periphery of the pin, the inner surface of the bush has a continuous groove whose inner end is open to the grease reservoir. ,
A sash-shaped oil groove is provided, and a spiral oil groove or parallel to the axis of the pin is provided on the outer periphery of the pin in a range slightly shorter than the lip contact interval of the left and right dust seals. A bearing structure characterized in that the terminal part is opened on the inside of the lip abutting part of the dust seal.
