Further, the first and second vertical partition walls 31 and 33 are gradually thickened from the front to the rear.

That is, the inner side surface 25, the outer side surface 27, and the first and second vertical partition walls 31 and 33 gradually become thicker from the front to the rear.

The first and second horizontal partition walls 35 and 37 are disposed in parallel with the rear surface 23 to connect the inner side surface 25 and the second vertical partition wall 33 with each other.

At this time, the first and second barrier ribs 35 and 37 are formed at regular intervals by dividing the inner surface 25 into three equal parts.

Further, each of the partitions has a change in thickness t from front to rear.

That is, the thickness t37 of the second horizontal barrier ribs 37 is thicker than the thickness t35 of the first horizontal barrier ribs 35. The first and second horizontal barrier ribs 35, The thicknesses t35 and t37 of the front surface 21 and the rear surface 23 are thinner than the thicknesses t21 and t23 of the front surface 21 or the rear surface 23, respectively.

The first and second outer inclined partition walls 41 and 43 are formed by connecting the first and second horizontal partition walls 35 and 37 from the second vertical partition wall 33.

That is, the first outer inclined partition wall 41 is connected to one side of the outer side surface 27 connected to the front surface 21 at one side of the second vertical partition wall 33, And is connected to the central portion of the outer side surface (27) from the other side of the second vertical partition wall (33).
