PROBLEM TO BE SOLVED: To assembly a sash bar in a specific shape in the shape of a square frame without performing any complex machining. SOLUTION: A pair of glass slide frame sides 2 where a pair of recessed grooves 2b are connected via a protrusion 2a in an inverse recessed type are arranged oppositely, one end 2c of the glass slide frame sides 2 is fitted to a recessed large groove frame side 3 having a fitting recessed groove 3a having nearly the same width at right angle, the protrusion 2a of the other end 2d of the glass slide frame side 2 is fitted to a recessed small groove frame 4 having a fitting recessed groove 4a having nearly the same width at right angle for composing a square frame, one side 5a of an L-type connection piece 5 is inserted into bottom parts 3c and 4c of each of fitting recessed grooves 3a and 4a of the recessed large groove frame side 3 and the recessed small groove frame side 4 near each corner edge part of the square frame so that the other side 5b comes into contact with the outer surface of the bottom parts 3c and 4c of the other side 5b, one side 5a of the connection piece 5 is brought into contact with a front F or a rear R of the end parts 2c and 2d of the protrusion 2a, and at the same time, one side 5a of the connection piece 5 is connected to the projection 2a by a rivet.
