In this case, the arc angle of the third inner circumferential surface panel 130 or the fourth inner circumferential surface panel 140 becomes smaller than 32 °, and the outer diameter of the first and second outflow pipe members 710 described above becomes smaller. In this case, an arc angle of the third inner circumferential panel 130 or the fourth inner circumferential panel 140 may be greater than 32 °.

That is, when the arc angle of the third inner circumferential surface panel 130 or the fourth inner circumferential surface panel 140 is in the range of 22 ° to 42 °, most of the first and second outflow pipe members 710 and 720 It is an acceptable range for the outside diameter.
