PURPOSE: To enhance strength and its workability by simply and certainly attaching a holding body to be mounted at the center bending part of plural line stripes fixed and held, bent toward outside between upper and lower frames so as to be parallel with each other by using the upper and lower frames consti tuting the shade.

CONSTITUTION: A thinly shaped holding body 8 in which a recessed part 10 is groove-provided on an inner wall surface 9 is wound and attached with above recessed part 10 engaged with line stripe bodies 6 against a dressing frame composed of plural line stripe bodies 6 to be fixed and held, bent toward the outside between the upper and lower frames so as to parallel to each other by using upper and lower frames 3 and 4 constituting a shade. Thereby, attachment work of the holding body which enhances strength is made easier, and the strength can be improved certainly by means of engagement of the line stripe body constituting the dressing frame with the recessed part.
