Abstract

PURPOSE: To manufacture a rail of small weight and high strength, by dividing the cross section of the rail at a roller chain guide part, shaping the top, bottom and side of the rail to guide a trolley and providing a strength reinforcing part on the top or bottom of the rail.
CONSTITUTION: A roller chain is moved back and forth as an unendless line in a roller chain driver which is applied to a garage door opening and closing unit or the like. A rail 20 for guiding the reciprocation of the roller chain 22 is divided at a roller chain guide part 20-a. The side 20-b, top 20-c and bottom 20-d of the rail are so shaped that they are surrounded by a trolley 21. The increase in the width of the roller chain guide part 20-a is restricted by the roller chain 22, which is coupled by trolley pins 21d, attachments 23, etc. to move the trolley 21. A bending strength reinforcing projection 20e is provided on the top 20c of the rail to heighten its bending strength.
