<p><P>PROBLEM TO BE SOLVED: To provide a torque fluctuation absorber capable of stabilizing a function of a limiter section while suppressing the wear and deterioration of a friction material. <P>SOLUTION: A transmission torque limiter includes: a first plate member 11; a second plate member 14 which is urged toward the first plate member 11 and which can be rotated with respect to the first plate member 11; and the friction material 16 which is disposed between the first and second plate members 11 and 14, which is slidably brought into pressure contact with the first plate member 11, and which is held by the second plate member 14. The first plate member 11 is set to satisfy either or both of the condition that surface roughness Ra is in the range of 0.5-8.5 and the condition that the number Pc of surface projections per length of 4 mm is in the range of 10-120, on a surface 11b sliding with respect to the friction material 16. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
