  However, in such a conventional vehicle, since the internal combustion engine is installed so that the brake booster is opposed to the throttle body and the intake manifold, an external force is applied to the front portion of the vehicle from the front of the vehicle. When the internal combustion engine moves backward toward the dash panel, the throttle body and the intake manifold may interfere with the brake booster.

  Here, in order to prevent the throttle body and the intake manifold from strongly interfering with the brake booster, the longitudinal distance between the intake manifold and the throttle body and the brake booster is increased. However, in this case, the distance in the front-rear direction of the vehicle in the engine room becomes long, and the vehicle becomes large.
