摘要
A friction damper, which is used for a gear transmission device including a shaft element (2), a gear (1) into which the shaft element (2) penetrates, and a rolling element (4) interposed between the shaft element (2) and the gear (1), the shaft element (2) and the gear (1) being provided to be relatively rotatable around the shaft (2) center, includes : a core (8) attached to the peripheral surface of a fixed member which is either the shaft element (2) or the gear (1); and an elastic member (9) integrally provided with the core (8). The elastic member (9) has a lip which slides in contact with the peripheral surface of a rotating member which is either the shaft element (2) or the gear (1), and a plurality of lubricating oil paths formed on the rotating member in a circumferential direction. The core (8) includes a cylindrical part (10) fitted onto the peripheral surface of the fixed member, and a disk part (11) provided on the edge portion of the cylindrical part (10) on the rolling element (4) side so as to extend in a radial direction. The surface of the core (8) is subjected to a hardening process.
