PROBLEM TO BE SOLVED: To safely, effectively mount an outdoor unit by providing a rail engaging member having a recess for intruding a rail, and a rail retaining part having an elastic pawl engaged with a side extended axially of the rail, and forcing the rail into the recess of the member. SOLUTION: Fitrst, a rail engaging member 11 in which a rail retaining part 22 is connected by spot welding S is placed at a predetermined position of the rail 3 of a window sash 2, and pressed down downward. Thus, the rail 3 is inserted into a rail inserting part 22a at a center of the part 22. Then, an elastic pawl 23 is bitten to an axially extended side of the rail 3, and engaged so that the rail is not to be retracted to be drawn out from the rail 3. Accordingly, even if screws 12, 13 are not engaged with th member 11, there is no fear that the member 11 is removed from the rail 3 unless a considerably strong force is applied to the member 11. |
