A rotary transmission mechanism is disclosed for use with an air/hydraulic cylinder or chuck, consisted of a cylindrical mount, an intermediate ring inserted in the cylindrical mount, a stepped inner socket inserted into the intermediate ring, a flow guide inserted in the stepped inner socket, a rear packing member covered on the flow guide, a front packing member connected to the rear packing member, a slide ring retained between the front and rear packing members, and a spindle fastened to the slide ring through a screw joint and inserted through all the aforesaid parts, wherein compressing a flow of compressed air through either of two inlet holes on the cylindrical mount causes the spindle to be moved forwards or backwards by the slide ring, and simultaneously causes the spindle, the flow guide, the stepped inner socket, and the rear and front packing members to be floated concentrically without producing any friction resistance.
