Abstract
Disclosed is a structure of a lower frame for a pivoted window, which prevents intrusion of rain water into the room. The lower frame has a grooved section, and a rotation shaft is mounted on the bottom plate of the groove portion to support the pivoted window. Ventilation holes are formed in a space defined by the lower frame and a lower rail of the pivoted window so that the ventilation holes are communicated with outer air and generation of a negative pressure in the above-mentioned space is prevented.
