description	[Problem] To provide a gyratory crusher serviced through an opening at the top for excellent serviceability, in which the amount of oil supplied can be controlled to maintain a sound oil film in a bearing portion; also to provide an oil supply structure and an oil supply method for such a gyratory crusher. [Solution] An oil supply structure (30) is a structure for supplying lubricating oil to both a first bearing part (41) and a second bearing part (42), the oil supply structure having an annular thrust seal (33) arranged on the inner side of a lower frame assembly (13) and supporting the bottom end of an inner cylinder bush part (14a) from below, a first oil supply inlet (31) opening in the bottom part of the lower frame assembly (13) so as to supply oil to the first bearing part (41), and a second oil supply inlet (32) opening in the inner peripheral surface of an outer cylinder bush part (13a) so as to supply oil to the second bearing part (42). The thrust seal (33) separates the flow channel of lubricating oil supplied from the first oil supply inlet (31) to the first bearing part (41), and the flow channel of lubricating oil supplied from the second oil supply inlet (32) to the second bearing part (42).
