2. Description of the Related Art Fasteners that utilize the attractive force of permanent magnets are
The male and female fasteners are brought into a connected state by the attraction and attraction of the permanent magnets, and the male and female fasteners in the coupled state can be separated by a pulling operation against the attraction and attraction.
It is easy to handle, and the structure for locking with male and female fasteners can be relatively simple.As a result, it is possible to cover bags such as handbags, school bags, shoulder bags, and lids such as bags. For various purposes, such as a means to fasten the main body in the closed state, a means to fasten the lids of various boxes to the box main body in the closed state, a means to fasten various belts to each other or to a bag, etc. Used.

However, this kind of permanent magnet attraction,
The fastener using the attractive force has a disadvantage that the male and female fasteners are easily separated when a force greater than the attraction and attractive force of the permanent magnet acts on the male and female fasteners. Even when the tool is impacted, there is a disadvantage that the male and female fasteners in the fastening state are easily separated.

From this point of view, it has a ferromagnetic female fastener having a hole through which the protrusion of the male fastener is inserted, and a protrusion having a head projecting laterally beyond the shaft portion. A fastener including a male fastener having a permanent magnet attached to a seat portion provided is used. In this type of fastener, while inserting the protrusion of the male fastener into the hole of the female fastener, the female fastener is attracted to the permanent magnet of this male fastener to make it the temporary fastening state, and then the male fastener By twisting the protrusion, the head portion that projects to the side of this protrusion is positioned on the plate part surface around the hole of the female fastener so that the protrusion of the male fastener does not come out from the hole of the female fastener. It was used in the state that it was fixed.

[0005] With such a fastener, while the fastening state of the male and female fasteners can be reliably maintained, it is necessary to twist the projections of the male fastener inserted into the female fastener one by one, and especially the fastening of the male and female fasteners. When releasing the state, it is necessary to twist the protrusions of the male fastener and pull the male and female fasteners apart from each other, which makes the engaging and disengaging operation of the male and female fasteners complicated.

In this respect, attempts have been made to improve this type of fastener, particularly to provide a handle that is easy to handle. As a typical fastener, the engagement tool of Japanese Patent Publication No. 3-14983 has been proposed. .

The ferromagnetic plate attracted and attracted to the projecting portion is scratched by the projecting projecting portion on the projecting portion.

[0008]

However, this type of engaging device has the disadvantages that it is not always easy to assemble the parts constituting the engaging device, and the appearance itself is not neat.

The present invention aims to further improve the invention of Japanese Patent Publication No. 3-14983. That is, the structure of the female fastener, which is one of the fasteners, is simplified, the number of components is reduced, and moreover, the components of the female fastener are correctly assembled and inserted into this female fastener.
