摘要 PCT No. PCT/JP87/00930 Sec. 371 Date Jul. 27, 1988 Sec. 102(e) Date Jul. 27, 1988 PCT Filed Nov. 30, 1987 PCT Pub. No. WO88/04373 PCT Pub. Date Jun. 16, 1988.A damper disc having a hub flange divided into a peripheral side flange divided into an inner peripheral side flange having a hub and an outer peripheral side flange which are meshed with each other with a circumferential clearance therebetween. Annular sub plates, holding both side flanges, are installed on opposite sides of the flanges. A relatively weak torsion spring is interposed in a recession and a rectangular hole is provided at a positon where the sub plates face on the inner peripheral side flange. Inner peripheral parts of the sub plates are pressed on opposite side faces of the inner peripheral side flange. A retaining plate and a clutch plate are provided on outside faces of the sub plates opposite to a flange through a friction material having a relatively high friction coefficient. An intermediate member and a second friction material having a relatively low coefficient, the retaining plate and the clutch plate are coupled by a stop pin at an outer peripheral part so as to compress both the friction materials. The intermedate member has claws fitted in holes in the retaining plate and the clutch plate in such manner that the claws can move freely in a circumferential direction within a specified torsion angle. Relatively strong torsion springs are compressively installed in rectangles holes in the retaining plate, the clutch plate and the outer peripheral side flange at a position where the retaining plate and the clutch plate face the outer peripheral side flange. A key piercing the outer peripheral side flange, the inner peripheral side flange and both sub plates, in an approximately center line direction is positioned so as to be urged toward an outer periphery of the damper disc. Notches on the inner peripheral side flange and the sub plates hold the key freely slidingly in a radial direction of the disc. A force for holding the key at circumferential end faces of both notches sets and holds the key between both sides end faces for relatively high torsion angular velocity of the damper disc and for releasing the key from the end faces for relatively low torsion angular velocity of the damper disc.
