The door member 3 is pressed against the frame member 2 by the tightening force. Since the corner | angular part of the latching | locking part 22d is tapering at this time, the 2nd fastening handle | steering-wheel 6 can be easily climbed and engaged with the latching | locking part 22d.

  The door-side convex portion 32 faces an appropriate position in the width direction of the receiving portion 22 c, and the first water stop member 26 on the frame member 2 side becomes the door-side convex portion 32 by the pressing of the door-side convex portion 32. It is deformed and adhered in a watertight manner. Further, the frame-side convex portion 22 e (20) faces an appropriate position in the width direction of the groove portion 34 provided in the door main body 30, and the second stopper that is internally fitted in the groove portion 34 by pressing of the door main body 30. The water member 36 is deformed and adhered in a watertight manner to the frame-side convex portion 22e (20).

  As described above, the water tightness can be maintained by the first water stop member 26 and the door-side convex portion 32, and further, the water tightness can also be maintained by the second water stop member 36 and the frame-side convex portion 20. Even if any one of the first water stop member 26 and the second water stop member 36 is damaged, it is possible to prevent water from entering the inside.
