摘要： The present invention has an object to provide a balance shaft friction damper (1) capable of preventing a torque reduction of a lip sliding surface while ensuring an axial flow path for a lubricant to stably circulate the lubricant. The object is achieved by a balance shaft friction damper (1) including: a metal mounting ring (10) that is mounted in an annular gap (300) between a shaft portion (100) of a balance shaft of an engine and a gear portion (200) provided on an outer periphery of the shaft portion (100), and has a fitting surface (11a) fitted and secured to one of an outer peripheral surface (101) of the shaft portion (100) and an inner peripheral surface (201) of the gear portion (200); and an annular elastic ring member (20) made of a rubber-like elastic material and provided on the mounting ring (10), and has a lip sliding surface (21a) brought into close contact with the other of the outer peripheral surface (101) of the shaft portion (100) and the inner peripheral surface (201) of the gear portion (200), wherein an oil flow path portion (30) that allows axial circulation of a lubricant is formed in a position across the mounting ring (10) and the elastic ring member (20) and apart from the lip sliding surface (21a), and/or an oil flow path portion (30) that allows axial circulation of a lubricant is formed in a position in the mounting ring (10) and apart from the lip sliding surface (21a).
