The fixing holes 425 are formed at a plurality of locations in the longitudinal direction of the lower frame 4 and are formed at positions that do not overlap the handle attachment holes 415 in the prospective direction.

[Composition of lower frame cover material]
A synthetic resin lower frame cover member 50 is attached to the finding surface 41, the prospective surface 42, and the flange portion 44 that are indoor exposed surfaces of the lower frame 4. The lower frame cover member 50 includes a finding covering portion 51 that covers the finding surface 41, a prospect covering portion 52 that covers the prospective surface 42, and a flange covering portion 54 that covers the flange portion 44. It is arranged between the frame 4 and the operator handle 20.
The finding covering portion 51 and the prospecting covering portion 52 are connected so as to be substantially orthogonal at a corner portion 53 (corner portion), and are configured to have a substantially L-shaped cross section.

A handle attachment hole 515 that opens at the same position as the handle attachment hole 415 when the lower frame cover member 50 is attached to the lower frame 4 is formed in the finding covering portion 51.
The prospective covering portion 52 is formed with a fixing hole 525 that opens at the same position as the fixing hole 425 when the lower frame cover member 50 is attached to the lower frame 4.
An engaging portion 521 that engages with the protrusion 421 is formed at the tip of the prospective covering portion 52. On the lower surface of the flange covering portion 54, an engaging groove portion 541 that engages with an end portion of the flange portion 44 is formed.

A watertight material 60 is bonded to the lower frame cover material 50. The watertight material 60 is made of a sheet material made of ethylene, propylene, diene rubber (EPDM) or the like, and is bent around the corner portion 53 of the lower frame cover material 50 so as to be formed into the appearance covering portion 51 and the expected covering portion 52. By bonding, the cross section is substantially L-shaped. The watertight member 60 is disposed over the entire length of the lower frame cover member 50 in the longitudinal direction (the width direction of the lower frame 4), and is bonded to the lower frame cover member 50.
The watertight member 60 includes a vertical portion 61 that is bonded to a surface of the find covering portion 51 that faces the finding surface 41, and a horizontal portion 62 that is bonded to the lower surface of the prospective covering portion 52. 62 is continuous at the corner 63. Here, the upper end of the vertical portion 61 is configured to be positioned below the handle mounting hole 515, and the tip on the indoor side of the horizontal portion 62 is configured to be positioned on the outdoor side of the fixing hole 525. Yes.

When the lower frame cover material 50 to which such a watertight material 60 is bonded is attached to the lower frame 4, the protrusions 411, the protrusions 421, and the protrusions 422 are found and covered 51 as shown in FIG. 2. , Abuts against the expected covering portion 52. For this reason, gaps 71 and 72 are formed between the finding surface 41 and the finding covering portion 51 and between the prospective surface 42 and the expecting covering portion 52, respectively. The watertight material 60 is disposed in the gaps 71 and 72.
At this time, since the thickness dimension of the watertight material 60 is set larger than the dimension of the gaps 71 and 72, the watertight material 60 is compressed and is in close contact with the lower frame 4. That is, the vertical portion 61 is in close contact with the finding surface 41, the horizontal portion 62 is in close contact with the prospective surface 42, and the corner portion 63 is in close contact with the corner portion 43.
Further, the protrusion 412 of the finding surface 41 bites into the vertical portion 61, and the protrusion 423 of the prospective surface 42 bites into the horizontal portion 62. For this reason, especially the corner | angular part 63 closely_contact | adheres to the corner | angular part 43 reliably.
Further, the vertical portion 61 of the watertight material 60 is disposed below the height position of the lower ends of the handle mounting holes 415 and 515, and the horizontal portion 62 of the watertight material 60 is located on the side of the finding surface 41 of the fixing holes 525 and 425. It is arrange | positioned rather than the edge position on the finding surface 41 side. Therefore, the watertight member 60 is provided between the lower frame 4 and the lower frame cover member 50 between the height position of the lower end of the handle mounting hole 415 and the edge position of the fixing hole 425 on the side of the finding surface 41. It has been.

[Joint of lower frame and vertical frame]
As shown in FIGS. 1 and 4 and 5, both ends of the lower frame 4 are joined to the vertical frames 5 and 6. Here, as described above, the vertical frames 5 and 6 are provided with the vertical frame cover members 8 and 9 made of synthetic resin. The vertical dimension of the vertical frame cover members 8 and 9 is shorter than the vertical dimension of the vertical frames 5 and 6. For this reason, the lower end of the vertical frame cover material 8 is located above the lower end of the vertical frame 5.
On the other hand, in the lower frame 4, both end portions of the finding surface 41 and the prospective surface 42 are cut out, and the length dimension in the left-right direction of the finding surface 41 and the prospective surface 42 is made shorter than the other lower frame 4 portions. ing. The length of the lower frame cover member 50 in the left-right direction is substantially the same as that of the finding surface 41 and the prospective surface 42. For this reason, inclined upper surface portions 45 that are continuous with the outdoor side of the finding surface 41 are exposed at both ends of the lower frame 4. A watertight material 70 for bonding is bonded to the upper surface portion. The bonding watertight material 70 is a watertight material made of EPDM or the like, similar to the watertight material 60.

When the lower frame 4 and the vertical frames 5 and 6 are joined, as shown in FIG. 5, the lower surfaces of the vertical frame cover members 8 and 9 abut against the upper surface of the joining watertight material 70. It is sandwiched between the lower frame 4 and the vertical frame cover materials 8 and 9.
The side surface of the watertight material 70 for bonding is in contact with the side surface of the horizontal portion 62 of the watertight material 60. Thereby, the water stop line of the watertight material 60 and the water stop line of the watertight material 70 for joining continue.

In the present embodiment having such a configuration, when water enters the gap 71 from the handle mounting hole 415, the watertight material 60 is disposed and blocked in the gap 71, so that the water flows into the gap 72. Can be prevented. Since water does not flow into the gap 72, it is also possible to prevent water from flowing from the fixing hole 425 into the housing.
In addition, the water flowing along the surfaces of the vertical frame cover members 8 and 9 of the vertical frames 5 and 6 flows to the upper surface portion 45 of the lower frame 4, but since the bonding watertight material 70 is disposed, It is possible to prevent the frame cover materials 8 and 9 from flowing into the housing from the gaps between the lower ends and the upper surface portion 45.

[Effect of this embodiment]
(1) Since the watertight member 60 is provided between the lower frame 4 and the lower frame cover member 50, the watertight member 60 does not protrude from the lower frame 4 or the lower frame cover member 50 and is not exposed to the outside. For this reason, it can prevent that the designability of the vertical sliding window 1 falls.
(2) Since the water flowing into the gap 71 from the handle mounting hole 415 of the lower frame 4 is blocked by the watertight material 60 and stopped, it can be prevented from flowing into the gap 72 and flows from the fixing hole 425 into the housing. Can also be prevented.
(3) Since the watertight member 60 includes the vertical portion 61 and the horizontal portion 62 and is formed in a substantially L shape, the corner portion 63 can be easily adhered to the corner portion 43. For this reason, the water flowing in the vertical direction along the finding surface 41 and the water flowing in the horizontal direction along the prospective surface 42 can be stopped by the single watertight member 60, and the water stopping The performance can be easily improved.
(4) Since the watertight material 60 can be formed in an approximately L shape by bending and bonding the EPDM sheet along the finding covering portion 51 and the prospecting covering portion 52, the lower frame cover material 50 is securely attached. And can be stably fixed. Furthermore, since the variation in the thickness dimension of the watertight material 60 can be reduced, the watertight material 60 can be reliably attached to the finding surface 41 and the prospective surface 42.

(5) Since the watertight member 60 is in contact with the bonding watertight member 70, the water stop line in the lower frame 4 can be connected to the water stop line at the joint between the lower frame 4 and the vertical frames 5 and 6. For this reason, when the water stopped by the watertight material 60 flows in the left-right direction through the gap 71 and flows from the end face of the gap 71 to the vertical frames 5 and 6, the water is stopped by the bonding watertight material 70 and the housing side Can be prevented.
At this time, in particular, since the water-tight material 60 includes the horizontal portion 62, the contact area with the water-tight material for bonding 70 disposed on the upper surface portion 45 of the lower frame 4 can be increased, and the water stop line is reliably connected. Can be made.
(6) Since the protrusions 412 and 423 are formed on the finding surface 41 and the prospective surface 42 and bite into the watertight material 60, the position of the watertight material 60 can be prevented, and the adhesion of the watertight material 60 to the lower frame 4 is improved. The water stop performance can be improved. In particular, since the protrusions 412 and 423 are formed at positions sandwiching the corner portion 43, the corner portion 63 of the watertight material 60 can be reliably brought into contact with the corner portion 43.

(7) Since the horizontal portion 62 of the watertight material 60 is disposed closer to the finding covering portion 51 than the fixing hole 525 and is disposed at a position away from the fixing hole 525, screws are attached to the fixing holes 525 and 425. When screwed, it is possible to prevent a hole from being formed in the watertight material 60 by the screw. For this reason, the water stop performance by the watertight material 60 can be stabilized.
(8) Furthermore, since the watertight material 60 made of EPDM or the like is used, the working time can be shortened compared to the case where the sealing process is performed.
