<p>PROBLEM TO BE SOLVED: To reduce assembly cost of a roll blind provided with a detachable screen. SOLUTION: A roll blind is composed of a screen 1 on which one half part 3 of a jointing member 2 is installed at an upper edge part, and a roll pipe 5 on which the other half part 4 of the jointing member 2 is installed at a locking groove 6 formed in an outer circumferential surface. The jointing member 2 is formed of a thermoplastic synthetic resin having elasticity, a projected protrusion 7 having a swollen part 9 is formed at a tip of one half part 3, a recessed protrusion 8 having a receiving part 10 in which the swollen part 9 is elastically engaged is formed on the other half part 4, and depth of the locking groove 6 is set to be roughly similar to thickness of the jointing member 2 when coupled.</p> |
