More Information
Summary:A joint mechanism includes a motor including a motor shaft and a hypoid pinion provided at a tip end of the motor shaft and a speed reducer configured to reduce a rotation speed of the motor at a speed reduction ratio. The speed reducer includes a screw-shaped input shaft and a ring-shaped gear meshing with the screw-shaped input shaft and three-dimensionally intersecting the screw-shaped input shaft at a right angle. Further, the screw-shaped input shaft includes a shaft body provided with a screw portion and a hypoid gear arranged at one end of the screw-shaped input shaft and configured to mesh with the hypoid pinion. Furthermore, the screw-shaped input shaft has an axis three-dimensionally intersecting the motor shaft at a right angle. Most Illustrative Drawing: Fig. 2
