PCT No. PCT/JP86/00038 Sec. 371 Date Nov. 10, 1986 Sec. 102(e) Date Nov. 10, 1986 PCT Filed Jan. 31, 1986 PCT Pub. No. WO86/04654 PCT Pub. Date Aug. 14, 1986.In an operation chamber 19 filled with silicone oil, there is provided a first resistance plate 21, which is spline-mated to the outer circumference of a first transmission shaft 3, and a second resistance plate 23, which is spline-mated to a second transmission shaft 9. These two resistance plates 21, 23 are clamped at both sides thereof by a clamp means formed from a pair of ring members 27, 29. The ring members 27, 29 are joined to a piston formed from the first transmission shaft 3, the sideplate 11, and a stopper ring 25. Then, when this piston moves in thrust and the clearance between the ring members 27, 29 shrinks, the blocks of the first resistance plate 21 and the second resistance plate 23 arranged side by side are clamped and abutted closely to produce a friction force at the resistance plates 21, 23. |
