The lower frame upper surface cover 222 has a U-shaped engaging portion 222a formed in a sheet shape and formed at an end portion on the outdoor side. The U-shaped engaging portion 222a is engaged with the lower frame 22 at the end portion of the upper surface of the lower frame 22 on the outdoor side in the indoor / outdoor direction. The lower frame top cover 222 is made of, for example, a stainless steel material.

The side guide 26 has an inverted U-shaped inverted U-shaped portion 261 that opens downward, and an extended mounting piece 265 that extends rearward from the indoor end of the inverted U-shaped portion 261.
The extended mounting piece 265 is fixed to the upper surface of the lower frame 22 in a state of being arranged between the lower portion of the rubber fixing frame 27 and the lower frame upper surface cover 222.

As shown in FIGS. 9, 11 and 13, a front surface 262 is formed on the outdoor side surface of the inverted U-shaped portion 261. The front surface 262 has a width in the vertical direction and extends in the horizontal direction. As shown in FIG. 9, a packing member 34 attached to the lower part of the slide door 3 is pressed against the front surface 262. A horizontally long gap 263 extending in the left-right direction is formed in the lower part of the front surface 262.

The horizontally long gap 263 is a gap between the lower end portion of the front surface 262 and the upper surface of the lower frame 22. The horizontally long gap 263 is formed on the outdoor side surface of the side guide 26, at the lower part of the front surface 262, is formed so as to open toward the front side, and extends in the left-right direction. When the door end side guide roller 36 moves in the left-right direction, the arm portion 363 of the door end side guide roller 36 is inserted into the horizontally long gap 263 so as to be movable in the left-right direction. The length of the horizontally long gap 263 in the vertical direction is formed to be larger than the thickness of the arm portion 363 of the door end side guide roller 36 and smaller than the height of the portion of the roller portion 361 of the door end side guide roller 36. As a result, the roller portion 361 of the door end side guide roller 36 cannot be inserted from the horizontally long gap 263, and the roller portion 361 of the door end side guide roller 36 inserted from the guide roller insertion portion 264 is inserted into the horizontally long gap. Never go out of 263.

As shown in FIG. 14, a guide roller insertion portion 264 (guide member insertion portion) is formed at one end of the horizontally long gap 263 on the vertical frame 23 side in the left-right direction.
