Abstract
Disclosed is a rotatable-and-swingable type of rotary joint device according to the present invention comprises at least an input shaft rotatably fixed to the casing of the device, a precession spherical body responsive to the rotation of the input shaft for rotating and swinging, and an output shaft operatively connected to the precession spherical body for rotating. This arrangement permits the crossing of the input and output shafts to change freely within certain angular limits, thereby substantially increasing the versatility of designing, and contributing to the down-sizing of the drive transmission.
