PROBLEM TO BE SOLVED: To provide a window frame which, when a modification window is installed with the nearly entire part of a gap between an existing window frame and a newly installed window frame being filled with form hardened body, can temporarily fix the newly installed window frame to the existing window frame with great appearance and good efficiency, and also to provide a window frame which, when a window is newly installed with the nearly entire part of a gap between a wall part and the newly installed window frame being filled with form hardened body, can form a caulking groove with an appropriate depth between a peripheral part on the outdoor side of the newly installed window frame and an opening part in order to prevent intrusion of rain water.SOLUTION: The present invention relates to a window frame in the present invention, which comprises a shield part with a substantially straight-line cross section, substantially perpendicularly protruding to an outer peripheral direction from an outdoor-side tip part of a peripheral part of the window frame. The window frame preferably has a fixing part with a substantially straight-line cross section, substantially perpendicularly protruding to an outer peripheral direction from a position closer to indoor-side than the shield part from the peripheral part of the window frame. |
