PURPOSE:To keep the tilt angle of a blind constant for a long period of time, by making up plural insertion holes between an opaque part and a transparent part abutting upon a blind resinoid plate, while inserting a supporting arm, which has an engaging concave carrying the same angle as a bending angle of the resinoid plate, into the insertion hole. CONSTITUTION:A blind resinoid plate 1 using transparent plates is made up in alternate arrangement of opaque parts 2 and transparent parts 3 as a continuous pattern and installed in the rear window of a car so as to cause the opaque part 2 to intercept the solar rays from rearward, making the transparent part 3 interpose between a driver and the range of rearward vision after being bent in stairs form. And, at both sides of the resinoid plate 1, plural insertion holes 4 each of which consists of two large diametral oval shaped holes 5 and one small diametral connecting hole are extendedly formed up between the opaque part 2 and the transparent part 3. On the other hand, with soft resinoid members use, a trapezoidal concave 8 whose angle is congruous with the bending angle of the said resinoid plate 1 is made up at one side, forming a supporting arm 7, and this arm is inserted into one of the insertion holes 4 whereby the resinoid plate 8 is kept constant. |
