TRAVELING TRUCK CARRIER RAIL WITH INTEGRALLY FORMED FLUID PROPULSION PASSAGE

摘要

PROBLEM TO BE SOLVED: To stably run a traveling roller and improve workability of installation and dismantling. SOLUTION: In a traveling truck carrier rail 3 utilizing fluid such as compressed air so as to move an internal moving body within a fluid propulsion passage 1 by supplying fluid such as compressed air to the fluid propulsion passage kept in airtightness by a pressure receiving member and a slit sealing member and so as to transmit the moving to an external traveling truck 4 via a connecting member, an outer peripheral surface of the fluid propulsion passage 1 is formed flatly, contact area of the plurality of traveling rollers 16 mounted on the traveling truck 4 with an outer peripheral surface of the traveling truck carrier rail 3 is increased and the traveling truck 4 can be stably run.
