Abstract
The seal structure includes a shaft member, a bush having a shaft hole for passing the shaft member, a pressure-receiving member having a facing surface facing an end surface of the bush on one side in the direction of the axis, and an elastic member that presses the bush against the pressure-receiving member from another side in the direction of the axis, in which a first coating layer is formed between an outer peripheral surface of the shaft member and an inner peripheral surface of the shaft hole of the bush, and a second coating layer is formed between the end surface of the bush on one side in the direction of the axis and the facing surface of the pressure-receiving member.
