摘要

PROBLEM TO BE SOLVED: To provide a guide rail for an overhang door, the manufacturing cost of which can be reduced. SOLUTION: A downwards U-shaped sectional rail body section 5 composed of an upper plate section 2 and both-side plate sections 3 and 4 is formed of one steel plate material while the first flange section 6 is bent and extended inwards horizontally from the lower end of one side plate section 3 of the rail body section 5 and the first rail section 7 is folded back and superposed so as to form a sideways T-shaped cross section together with the first flange section 6 at the front end section of the first flange section 6 and formed in an I-shaped cross section. The second flange section 8 is bent and extended inwards or outwards horizontally from the lower end of the other side plate section 4 of the rail body section 5, and the second rail section 9 is folded back and superposed so as to form the sideways T-shaped cross section together with the second flange section 8 at the front end section of the second flange section 8 and formed in the I-shaped cross section.
