2. Description of the Related Art As an adsorption tool using a permanent magnet, one having various shapes and structures is used in various fields. This type of suction tool, which is previously fixed to a target object such as a sheet, and the target object is used as a means for attaching the target object to another target object, for example, a wall surface, For example, there is a suction tool as shown in FIG. 12 and a stop structure for the suction tool.

The suction tool F shown in FIG.
Exceeds the peripheral side of the circular plate portion 101, and the peripheral side plate portion 102
And a permanent magnet 120 housed in the case 100. The attraction tool F is attached to an object to be attached G such as a sheet.
It is configured to include a stopper 130 as a means for fixing to.

The suction tool F used here is magnetized in the thickness direction, and moreover, the hole 121 is directed in the magnetization direction.
Of the permanent magnet 120 and the case 100 having a hole 103 communicating with the hole 121 of the permanent magnet 120, and the permanent magnet 120 is provided in the peripheral side plate portion 102 of the case 100. The magnet 120 is housed in the hole 121 of the permanent magnet 120 and the case 100.
Of the permanent magnet 120 so as to communicate with the hole 103 of the
Is adhered to the case 100 with an adhesive 140.

The stopper 130 used for fixing the suction tool F has a collar-shaped head portion 131 and the head portion 131.
And a resilient locking piece 133 provided at the tip of the leg portion 132, which is inserted into the hole 103 and surrounds the hole 103. It is configured to be locked to the surface of the plate portion 101 of 100.

[0007]

The suction tool F having such a structure has the hole 103 through which the leg portion 132 of the stopper 130 is inserted.
Is a hole 12 formed between the magnetic poles of the permanent magnet 120.
Since the leg portion 132 of the stopper 130 inserted into the hole 103 has a feature that it can be visually recognized from the hole 121, the hole 121 extends across the magnetic pole direction of the permanent magnet 120. Must be provided, causing various inconveniences to the suction tool F due to the provision of the hole 121.

First, when the permanent magnet 120 is formed in the shape of an annular plate, for example, when it is manufactured by sintering like a ferrite magnet, it is placed in a mold formed in the shape of an annular groove.
Since it is necessary to uniformly fill the sintered powder, manufacturing is difficult,
In addition, there is a problem that the molding cost of the permanent magnet 120 is relatively high, such as a defective product caused by distortion during sintering. In addition, such a ring-shaped permanent magnet 1
When 20 is manufactured by, for example, a method of forming a hole in a ferrite magnet formed into a plate shape, the permanent magnet has a problem of being broken during the perforating process, and a large amount of defective products are generated due to the perforating.

Further, in the case of the permanent magnet 120 which is a sintered magnet such as a ferrite magnet and has a relatively large hole extending in the magnetic pole direction, the permanent magnet 120 is handled. At the time of, for example, attachment to the case 100, or when the configured suction tool F is attached to the attachment object G, and a slight amount caused by the use of the attachment object G with the suction tool F attached. Since it can be cracked by impact, it has the difficulty of being handled and restricted in many ways.

Further, the permanent magnet 120 having the holes 121 as described above has a relatively small magnetism with respect to the bulkiness of the outer shape thereof, and thus has a smaller magnetism than the bulkiness of the outer shape. However, there was a problem that the adsorption force became weak.

Further, on the suction side of the suction tool F, the peripheral side plate portion 102 of the case 100, the permanent magnet 120, the hole 121 of the permanent magnet, and the leg portion of the stopper 130 in the hole 121. All of the tip portions of 132 are shown, and as a result, the suction surface side of the suction tool F is not neat and has an inconvenient appearance.

In addition, a hole 1 is also formed in the suction tool F that is constructed.
Since 21 is opened, dust and the like are likely to adhere to the inside of the hole 121, and it is difficult to remove the attached dust and the like, and as a result, it becomes difficult to become a suction tool for a dirty image. It was

In view of the inconveniences of the conventional suction tool and its mounting structure, the present invention is easy to manufacture and assemble, and does not cause any inconvenience such as damage and has a good appearance and appearance. At the same time, it is an object of the present invention to provide a holding structure for an attraction tool that does not impair the attraction force of a permanent magnet.
