TRACK AND ITS JOINT PART STRUCTURE OF COMPRESSED GAS PROPULSION CARRYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a track for a compressed gas propulsion carrying device connectable so as to minimize gas leakage, and very simply performing aligning in a joint portion. SOLUTION: This track has the hollow part 10 of a circular cross section also a slit part both the parts of which are continued in a lengthwise direction. One side end surface is formed of a protruded thread 12 continued along the inner peripheral shape of the hollow part 10, and having taperingly fitted taper surfaces 12a in both side surfaces. Another side end surface has taper surfaces 13a adaptable to the surfaces 12a, and is formed so as to correspond with the protruded part 12. The threads 12 of adjoining tracks 1 and 1 each other are guided to the grooves 13 to buttedly connect the end parts of the tracks 1 and 1 with each other in the continued condition of the slit parts 11 with each other.
