The brace part connects motor and housing and has a length measured in a direction from motor to housing. The brace part is arranged on edge in an airflow direction and has a width measured in the airflow direction. The brace part has two limbs extending lengthwise in length direction of the brace part. The limbs are spaced apart from each other and delimit opposite sides of an opening formed by a punch-out in the flat material and extending along some of the length. The limbs are arranged one behind the other in airflow direction.
