摘要

The bar has a hollow tube (5) extended by a bend part (6) forming a support base on a body shell. The tube has an opening (11) placed at the right of a passage (9) which evacuates air contained in a cab interior. An extraction unit (12) mounted in the opening is open at one of its ends that is directly coupled to the passage so that the evacuated air is received in the unit (12) which allows the flow of air towards outside the vehicle.
