PURPOSE:To absorb vibration in a damper disc by contacting a planetary rotary member against the innercircumferential side of an internal rotary member and the outercircumferential side of sun rotary member while placing an expandable/ shrinkable resilient member in circumferential direction between the sun rotary member and a planetary carrier. CONSTITUTION:A planetary roller mechanism 5 is provided with a sun roller 6, a planetary roller 7, a planetary carrier 8 and an internal roller 9. The planetary roller 7 is contacting against the outercircumferential face of sun roller 6 and the innercircumferential face of internal roller 9. A springboard 15 in an insertion hole 12 of holder 11 is provided at the carrier section of each planetary roller 7. Consequently, said spring 15 is compressed between the insertion hole 12 of carrier 8 and the notch section 16 of sun roller 6 through rotation of carrier 8, to absorb the torsional torque. |
