Abstract: In a housing of a vehicle control device are formed a suction port for taking outdoor air and a discharge port for discharging air taken in through the suction port. A flow passage that connects the suction port and the discharge port is formed inside the housing. A blocking member, a radiator, and a blower are provided in the flow passage. The blocking member is provided at a position where the blocking member faces at least a portion of an opening face of the suction port in the flow passage and a distance between the blocking member and the suction port is in a predetermined range.

Abstract: Fixing holes are formed around an opening of a housing. Holding members are each inserted into a corresponding fixing hole and are fixed to the housing by swaging. Two or more holding members are each provided with a corresponding protrusion member. Fitting holes and first insertion holes are formed around a central opening of a packing and the protrusion members are each fitted into a corresponding fitting holes. The packing is attached to the housing by fitting each of the protrusion members into the corresponding fitting hole. Fastening members are each inserted through a corresponding first insertion hole and a corresponding second insertion hole formed in a cover and are inserted into and fixed to holding members other than the above-described two or more holding members, so that the cover is attached to the housing.
