[0100] Under the action of the first contraction portion 291a of the first sidewall 291 and the second contraction portion 292a of the second sidewall 292, the flow path of the airflow entering from the cooling fan 240 (the planar cross-section of the flow path formed by the first sidewall 291 and the second sidewall 292) can narrow as the airflow travels in the discharge direction. Under the action of the first diffusion portion 291b of the first sidewall 291 and the second diffusion portion 292b of the second sidewall 292, the flow path of the airflow passing through the first contraction portion 291a and the second contraction portion 292a (the planar cross-section of the flow path formed by the first sidewall 291 and the second sidewall 292) can widen as the airflow travels in the discharge direction.

The boundaries of the inlet section 294a and the flow section 294b can be aligned with the boundaries of the contractions 291a, 292a and the diffusers 291b, 292b. The flow section 294b can be recessed from the exhaust pipe 290 toward the wheel 210. The flow section 294b can be a recessed semi-tubular shape. The depth of the recess in the flow section 294b can be inversely proportional to the flow path narrowed by the plurality of contractions 291a, 292a. Thus, the flow rate of the airflow from the inlet section 294a through the flow section 294b to the outlet section 294c can be kept constant. Furthermore, it can reduce the flow resistance generated in the airflow from the inlet 294a through the flow section 294b to the outlet 294c.
