Therefore, in order to remove these dusts from the outside air, measures are taken such as passing the outside air taken as cooling air through a filter. For example, an inertia separation filter is one of the filters. Outside air is taken into the air passage from an opening provided on the side surface of the vehicle, and the outside air that has flowed into the air passage is blown to the inertia separation filter by a blower. The outside air blown to the inertia separation filter flows into the inertia separation filter from the intake port of the inertia separation filter, enters the tube connected to the intake port, and rotates spirally in the tube. The inertial separation filter is a system that removes dust contained in the outside air by centrifugal force generated during rotation. About arrangement | positioning with the air blower of an inertial separation filter, when installing in the inhalation | air_intake side of an air blower, it may install in the exhaust side of an air blower. In order to facilitate maintenance work on the inertial separation filter when installed on the exhaust side of the blower,
It has been proposed that an inertial separation filter is placed adjacent to the side of the vehicle, and an inspection port is provided on the side of the vehicle adjacent to the inertial separation filter to facilitate maintenance such as removal, repair, and cleaning of the inertial separation filter. ing.

When the outer skin on the side surface of the vehicle body forms a part of the air passage as in the conventional case, the connection portion between the outer skin of the vehicle body and the air passage requires airtightness and watertightness, and the structure is complicated. In addition, very high accuracy is required for the production and assembly of the car body, and if there are any errors in the connecting parts from the design stage, it will be difficult to assemble, and it will be necessary to repair and repair the connections. There was a problem.

は、一切の合わせ作業やシール作業が不要である。 In the structure proposed in the past, it is necessary to proceed with the can making operation while adjusting the dimensions of the vehicle body outer plate and the air passage 5 and to ensure the airtightness and water tightness of the air passage 5 and the vehicle body outer plate. It was. For example, if the verticality of the airway 5 and the verticality of the outer plate do not match, a gap occurs, and in order to prevent the gap, it is necessary to adjust the dimensions with the actual object every time, Requires time and effort. If there is a gap left, it will be flooded in the car when it rains. In the present embodiment, the air passage 5 can be configured to be completely independent from the vehicle body outer plate that constitutes the side surface of the vehicle body. The panel on the side of the vehicle body attached to the vehicle can be raised on the upper part of the vehicle body frame. That is, it is not necessary to weld the vehicle body outer plate and the air passage 5 and individual can making assembly is possible. Although there is a method using a sealant instead of the welding method, a working space necessary for the sealing work must be secured around the airway 5. In the present invention, no alignment work or sealing work is required.

して組込んだ取外し屋根２を車体１にかぶせるだけで組立作業が完了する。 In the present embodiment, it is possible to avoid a right angle structure that is difficult to assemble by separating the connection positions of the intake port 11, the intake air passage 4, and the blower 6 as much as possible inside the vehicle body 1. By assembling the cooling mechanism 20 on the side of the vehicle body opposite to the side of the vehicle body where the intake port 11 is provided, the connection of the intake air passage 4, the blower 6, and the air passage 5 can be assembled as a vertical structure. Therefore, even if vertical and flatness errors and eccentricity occur, the elastic packing and flange surface provided between the upper part of the blower and the intake air passage 4 on the roof side absorb the error, and airtightness, Ensure water tightness. The blower 6 is attached to the upper portion of the air passage 5 in advance, and the assembly work is completed simply by covering the vehicle body 1 with the removal roof 2 in which the intake air passage 4 is integrated.

Therefore, it is necessary to process an opening on the outer plate of the vehicle body 1. Absent.
Since the vehicle body 1 does not have an opening, the production of the vehicle body 1 is facilitated, and corrosion of the vehicle body due to dust from the outside can be prevented.

を構成する間隙に入り、腐食等を引き起こすことがない。 Further, by making the inspection port provided on the passage side of the machine room sufficiently larger than the inertia separation filter 9, it is possible to easily incorporate the inertia separation filter from the passage side. The inertia separation filter 9 is inserted into the air passage 5 from the inspection port 10, the tip is inserted into the alignment fitting, and the fixing hole 9 c provided around the inertia separation filter 9 is tightened with a bolt or the like. By using packing for each of the cooling air vent 5a for the airway and the exhaust air vent 5b for the airway on the inertial separation filter mounting surface 50 inside the airway 5, it is possible to achieve airtightness by simply tightening the fixing screw. Watertightness can be secured. At the time of inspection / cleaning, since the inertia separation filter 9 fixed in the air passage 5 from the inspection port 10 provided on the passage 15 side can be easily cleaned, maintainability is also improved. As described above, since the inspection port 10 is not a connection portion with the outside, dust from the outside air is collected by the cooling mechanism 20 and the vehicle body 1.
It does not enter into the gaps that make up and cause corrosion or the like.
