PROBLEM TO BE SOLVED: To provide a draining fitting for a sash, which can positively prevent leakage of dew condensation into a room. SOLUTION: The draining fitting for the sash is formed of a draining fitting main body 6 attached to a drain hole 25 formed in a sill 1, and a float 15. The draining fitting main body 6 has a peripheral wall 8 forming a drainage channel 13 along an inner periphery of the drain hole 25; a partition wall 11 protruding from the entire inner periphery of the peripheral wall 8 into the drainage channel 13 to narrow an opening 12 of the drainage channel 13, and having a flat lower surface formed thereon; and guide portions 14 formed in the inner periphery of the peripheral wall 8 at a plurality of locations, for guiding the float 15 upward and downward. The float 15 has a flat abutting surface 17 formed thereon, for abutting on a lower surface of the partition wall 11, and engaging portions 16 engageable with the respective guide portions 14. Each engaging portion 16 holds the float 15 in the drainage channel 13 along the guide portion 14 in a vertically movable manner, and abuts on the partition wall 11 to block the opening 12 when the float 15 is located at an uppermost floating location.
