The rear of the concavity is open with a wall surface has a mazelike path comprising an inner wall surface 9 and an outer wall surface 9b. As a result, water drops or the like in the air sucked is forced to hit against the wall surface thereby preventing them from entry into the cowling 2. COPYRIGHT: (C)1981,JPO&Japio
