The present invention relates to an air supply device for water saving shower, which is connected between a shower head and a hose and, more specifically, is used by reducing water injection quantity while maintaining water pressure by supplying the outside air to the inside through a gap (30) between a rotational body (10) and a fixing body (20). An outside wing of ring-shaped packing, which is coupled to an outer circumferential surface of an insertion unit (21) of the fixing body (20), sporadically adheres to an inner circumferential surface of an assembly groove portion of the rotational body to seal and block the gap to open the gap in case the outside air flows due to opening a hydrant. In case the outside air hardly flows by closing or slightly opening a hydrant, a gap is sealed and blocked again to prevent a conventional water leakage phenomenon through the gap, thereby providing excellent use efficiency. |
