Abstract
This invention provides a female-male engaging device with tapes having a flat shape and a good appearance, wherein a female engaging device and a male engaging device can be easily engaged and disengaged with each other. The female engaging device and the male engaging device are mounted to a side edge of a tape at intervals, the female engaging device is defined with a leg portion for sandwiching the edge portion of the tape, a cavity portion in front face of the leg portion, and a laterally long engaging hole in a front wall, and the male engaging device is defined with a leg portion for sandwiching the edge portion of the tape, a neck portion at a front face of the leg portion having a size substantially corresponding to that of the engaging hole, and a bulging engaging head at a front face of the neck portion having a constant width and a front face in a shape of a Rugby ball, a thickness of a center portion of the engaging head is larger than that of the engaging hole, and a thickness of each of opposite ends of the engaging head is smaller than that of the engaging hole. The engaging head is inserted from its opposite ends and engaged with the engaging hole, and the engaging head is disengaged from the engaging hole by pulling an end portion side. Because the engaging and disengaging operations are only in a plane direction, the operations are easy.
