A three-dimensional power transmission device is disclosed. The device has drive and driven yokes (11, 12) connected to drive and driven shafts (1, 2) and a middle yoke (3) hinged to both the drive and driven yokes (11, 12). First and second joint units (100, 200) connect the two yoke parts of the middle yoke (3) to the drive and driven yokes (11, 12) respectively. The two joint units (100, 200) transmit the rotating force of the drive shaft (1) to the driven shaft (2) through the three yokes while allowing the drive and driven yokes (11, 12), with the drive and driven shafts (1, 2) to be rotated around the first and second joint units (100, 200) at the same rotating angle and in the same direction as said drive yoke (1) being rotatable around the first joint unit (100) at an angle theta of 0 DEG < theta </= 90 DEG in any direction. |
