The ceiling side lid 30 is a plate type for opening and closing the ceiling side check window 12. The side wall side lid 40 is formed extending from one side end of the ceiling side lid 30 toward the bottom at right angles, And opens and closes the inspection window 13. The ceiling-side check window (12) has a handle.

In addition, a support base 50 may be constructed in which both side portions in the longitudinal direction are connected to the ceiling cover portion 30 and the side wall cover portion 40, respectively.

The support base 50 is connected to the ceiling lid 30 and the side wall lid 40 on both sides in the longitudinal direction when the ceiling lid 30 and the side wall lid 40 are integrated, Side lid 30 and the side wall-side lid 40 are separated from each other, only one side is connected to the ceiling-side lid 30 and the other side is not connected to the side-wall-side lid 40.

The lid 20 is formed with a rotary shaft 60 at the lower end of the side wall side lid 40.

The rotary shaft 60 is slidably inserted into the rail groove of the rail 14 from the upper portion to the lower portion thereof and rotates in the rail groove to guide opening and closing of the lid 20.

Such a right angle type lid 20 is supported by the angle side of the ceiling side lid portion 30 and is supported by the side wall side lid portion 40, so that there is no dispersion due to the load because of the dispersion effect.
