  The window disclosed in Patent Document 1 uses a window frame in which an upper frame, a lower frame, and a vertical frame having hollow portions are connected in a rectangular shape by a known connection technique. That is, both the longitudinal ends of the upper and lower frames are in contact with the opposing surfaces of the upper and lower ends of the inner vertical wall among the vertical walls forming the hollow portion of the vertical frame, and the vertical wall outside the vertical frame Screws that penetrate from the outside into the vertical frame are screwed into and connected to the screw holes formed in the upper and lower frames. The rainwater drainage device forms a concave groove for collecting rainwater received by the upper frame on the upper surface wall of the upper frame, uses the hollow portion of the vertical frame as a drainage passage, and uses the upper end of the vertical wall inside the vertical frame. A notch is provided in the groove, and rainwater is introduced into the drainage passage from the concave groove through the notch.

Therefore, first, since a notch is formed in the inner vertical wall that forms the hollow portion, it is necessary to confirm the orientation of the vertical frame during processing, and the processing operation is not easy. Second, since the screw penetrates the hollow portion of the vertical frame and is screwed into the screw hole of the lower frame, it takes time to connect and there is no problem in connection strength. Thirdly, since the screw head is exposed to the outside, there is a problem in appearance, so in the prior art, the corner that covers and shields the upper and lower ends of the vertical frame and the upper and lower ends of the drainage passage. A block is mounted, and the screw is passed through and screwed from the outside of the corner block, and a corner cover for hiding the screw head is further mounted on the outside of the corner block.
Therefore, conventionally, there have been problems in connection strength of window frames, workability for drainage device configuration, the number of parts, and labor.

  Thus, the problem to be solved by the present invention is to solve the above problem, that is, to improve the connection strength of the window frame and drainage in a window in which rainwater received on the upper frame is prevented from flowing along the front surface of the window. An object of the present invention is to provide a window capable of facilitating processing for device configuration, reducing the number of parts, and simplifying construction.
