    摘要: In an air intake device, a throttle body is sandwiched between an air cleaner case and an intake manifold which are connected in direct contact with each other. A gasket for preventing an air leakage is provided between the air cleaner case and the intake manifold radially outside the throttle body. Alternatively, crushable thin projections are provided on the top and the bottom surfaces of the flange. When the flange is sandwiched between the case and the intake manifold, the thin projections are crushed to provide seals therebetween.
