ABSTRACT:
A flow straightening grid30is provided at an area where the air flow turns about 180 degrees in an air path23, or in the vicinity thereof. Because of this, the air flow can be prevented from being disturbed in the air path23and, therefore, noise caused by the disturbance of the air flow can be reduced effectively.
