FIXED CONSTANT VELOCITY UNIVERSAL JOINT

摘要

A fixed constant velocity universal joint (1) having a plurality of torque transmission balls (30), wherein a twist angle is approximately zero when an input torque is 0 Nm in the torque-twist angle diagram. Also, in the torque-twist angle diagram, a torsional rigidity near the input torque of 0 Nm is within the range of 1.5 to 6 Nm/deg.
