In parallel with this, the slope portion 61 and the bracket portion 62 are raised. That is, the slope portion 61 is cut out along the slope portion cut line 52, and the slope portion 61 is temporarily bent at a substantially right angle with respect to the fifth side surface 35 along the slope portion fold line 53. In addition, the bracket portion 62 is cut out along the bracket portion cut line 54, and the bracket portion 62 is bent at a substantially right angle with respect to the fourth side surface 34 along the bracket portion fold line 55.

  Next, as shown in FIG. 3, the slope portion 61 is supported by the bracket portion 62. That is, it mounts on the bracket part 62, returning the inclination angle (bending angle) of the slope part 61. FIG. At this time, the latching piece 62 a of the bracket portion 62 is latched to the notch 61 a provided in the slope portion 61, thereby fixing the two to each other.

  Subsequently, the planar material 10 is sequentially bent at a substantially right angle along the third mountain fold line 23, the second mountain fold line 22, and the first mountain fold line 21. The fifth side surface 35 and the first side surface 31 are overlapped with each other. At this time, the L-shaped cut 41 and the L-shaped cut 43 are engaged with each other, and the L-shaped cut 42 and the L-shaped cut 44 are engaged with each other.
