<P>PROBLEM TO BE SOLVED: To prevent large thermal distortion from occurring on a discharge chute while restraining the rise of the manufacture cost of the discharge chute. <P>SOLUTION: A regulation wall 507 is provided on side frames 501 and 502, and a projection portion 305 projecting to the regulation wall 507 side is provided on the fixing device side of a portion to be supported 303. When the temperature of the discharge chute 300 rises, the projection portion 305 comes into contact with the regulation wall, so as to regulate elongation and displacement of the portion to be supported 303 in a direction parallel with a rotation center axial line L3, whereby the large thermal distortion is prevented from occurring on the discharge chute 300 without changing the material of the discharge chute 300. Therefore, the large thermal distortion is prevented from occurring on the discharge chute 300 while restraining the rise of the manufacture cost of the discharge chute 300. <P>COPYRIGHT: (C)2009,JPO&INPIT |
