1. A torque damper apparatus comprising:
driving clutch discs and driven clutch discs of a multiple disc clutch configured to transmit torque of an engine when press-contacted to each other and to cut-off the transmission of the torque when released from the press-contacted condition; a hub gear formed with a spline for holding the driven clutch discs and adapted to receive the torque under the press-contacted condition of the driving and driven clutch discs; damper springs having spring characteristics for damping variation of the torque transmitted via the hub gear; an urging member united to the hub gear by fastening means for transmitting the torque from the hub gear to the damper springs by urging the damper springs; and a torque transmitting member holding the damper springs and outputting the torque transmitted from the urging member via the damper springs; wherein the torque transmitting member comprises windows having a thickness dimension of the torque transmitting member sufficient to receive the fastening means, and wherein the hub gear and the urging member are fastened together by the fastening means within the windows, wherein at least a portion of the hub gear, at least a portion of the urging member, and at least a portion of the fastening means are disposed within the window.
