Abstract
A torque transmission coupling includes a rotating shaft and a drive pinion shaft for carrying out input and output transmission of a torque. A torque control part is arranged between the rotating shaft and the drive pinion shaft for controlling torque transmission between the rotating shaft and the drive pinion shaft on the basis of a frictional engagement caused by an electromagnetic force of an electromagnet. At least a portion of the torque control part is arranged in an outer periphery of a taper roller bearing rotatably supporting the drive pinion shaft, thereby allowing a shortening of an entire length of the torque transmission coupling.
