The vertebral body 40 includes a mounting base plate 41 and a rising piece 42, including a pair of downward protruding pieces 41a of the mounting base plate 41.

41a are a pair of grooves 4 formed in the upper wall 2a of the upper frame 2.
The male body 40 is attached to the upper frame 2 by screwing the bolt 46 into the back plate 45 which is fitted to the upper frame 3.43 and fixed to the upper wall 2a with screws 44.
It is installed on.

The rising piece 42 is inserted and fitted into the downward recess 33 to connect the female body 30 and the male body 40 so as to be slidable only in the in-plane direction. In other words, the female body 30 and the male body 40 have insertion fitting portions that are slidable only in the in-plane direction.

In addition, 47 is a cushioning material that avoids direct metal contact between the pair of vertical plates 32 and the rising piece 42 to prevent squeaks and noises.
This prevents galling and the like.

Further, a drainer 50 is attached across the lower frame 4 and the upper frame 2, and the drainer 50 is located on the outdoor side of the connector C.

In other words, lower frame 4. A presser edge 52 is attached to the outdoor side of the upper frame 2 with screws 53 via a connecting body 51, and the drainer 50 has an indoor/outdoor vertical piece 54. The upper part of the piece 54 is placed in the downward recess 4b of the lower frame 4. The screw 5 is fitted through the sealing material 58.
