PROBLEM TO BE SOLVED: To provide the bracket mounting structure of a sash locking device, in which a mounting piece, which is not the hollow section of a window frame, need not be thickened and the deformation of the mounting piece can be prevented even when a bracket is fixed onto the mounting piece such as a case when a heat-insulating cover is installed. SOLUTION: A fixing section 72B for a bracket 72 is mounted on a surface on the indoor side of a mounting section 32C, and a reinforcing member 80 is arranged on the outdoor side of the mounting section 32C. Even when the air pressure of negative pressure is applied only to the bracket 72, with which a cam latch handle 71 is engaged, the load of the bracket 72 can be borne by the reinforcing member 80. Thus, the deformation of the first projecting piece 32 can be prevented, the first projecting piece 32 of a window frame 2 need not be thickened, and the window frame 2 can be used in common with other sashes.
