As shown by the same reference numerals in FIGS. 3 and 4, the left and right vertical stiles 12, 13 are an outdoor part 22 and an indoor part 23, each of which is divided into two parts in the expected indoor / outdoor direction, except for the mating side frame. Consists of Although the cross-sectional shape and the size of the horizontal frame and the vertical frame are different, they are basically the same structure. Therefore, the upper horizontal frame 10 will be described below.
Regarding the lower frame 11 and the left and right vertical frames 12, 13, the vertical and horizontal relationship may be considered with this as the center.

The outdoor portion 22 is an extruded material (metal portion) of an aluminum alloy, and a dovetail groove 24 is formed in a lower portion of the indoor side surface.
Is provided with a receiving groove 25 in the upper part. The dovetail groove 25 of the outdoor portion 22 is open to the indoor side, and has an outer (inner peripheral surface) wall 26 constituting the groove. The receiving groove 25 has a U-shaped cross section and opens to the inner peripheral surface. I have. As described above, the dovetail groove 24 and the receiving groove 25 have different groove cross-sectional forms.

The indoor side portion is a hard vinyl chloride extruded product (synthetic resin portion). A convex portion 27 having a narrow base portion and a wide distal end portion is provided at a lower portion of the outdoor side surface, and an insertion portion 28 is provided at an upper portion.
In the present embodiment, a tight material 29 made of soft vinyl chloride is integrally formed on the upper edge of the outdoor side surface in a cross section.
