A torque can be transmitted by a bushing 101 located between a pair of torque transmitting members. The bushing 101 is constructed out of resin and metal such that the part made of resin does not significantly contact the torque transmitting members. The bushing 101 includes an annular portion 102 m

A torque can be transmitted by a bushing 101 located between a pair of torque transmitting members. The bushing 101 is constructed out of resin and metal such that the part made of resin does not significantly contact the torque transmitting members. The bushing 101 includes an annular portion 102 made of resin and a connecting portion 103 made of metal. The connecting portion 103 is molded in an annular portion 102. The connecting portion 103 has parts (117 and 118), which are connected with the torque transmitting members so as to be able to transmit a torque therebetween. In a preferred embodiment, the bushing 101 is part of a dampening mechanism 6, which generates a friction between a hub flange 18 and a hub 3 when both of the portions rotate relatively. The bushing 101 supports a plurality of springs 21 to elastically couple a fixing plate 20 of the hub flange 18 to the hub 3. The bushing 101 rotates with the hub 3, while the fixing plate 20 rotates with the hub flange 18. The fixing plate 20 includes a first disk-shaped part 71 and a second disk-shaped plate 73. The second disk-shaped plate 73 engages bushing 101 to generate a friction therebetween when the hub 3 and the hub flange 18 rotate relative to each other.
