The magnet member 16 is composed of a hollow disk-shaped magnet 161 and a magnet cover 162 mounted on the surface of the magnet 161 that abuts the attraction plate 20. The magnet 161 uses ferrite, but may be a magnet alloy such as KS class, new KS class, MK class, and Alnico. The magnet cover 162 protects the magnet 161 from friction and impact, and is formed of a non-magnetic thin plate such as brass, so it does not weaken the magnetic force of the magnet 161. Further, the magnet cover 162 is provided with a through hole 164 having substantially the same diameter as the hollow portion 163 of the magnet member 16.

The suction plate 20 is made of a ferromagnetic material and is formed into a disc shape. The ferromagnetic material is, for example, iron, nickel, or an alloy containing these. A protruding edge 201 is provided on the peripheral edge of the suction plate 20. The inner diameter f at the portion of the protruding edge 201 in contact with the attraction plate 20 is formed to be equal to or slightly larger than the outer diameter e of the magnet member 16. The inner diameter of the protruding edge 201 gradually increases as the distance from the suction plate 20 increases. Therefore, the inner peripheral surface 203 of the projecting edge 201 acts as a guide surface for the magnet member 16. Further, it is desirable that the flange 201 is also made of the same ferromagnetic material as the attraction plate 20. This is because it can surely act as a guide surface.

The male member 22 is composed of a shaft 221 protruding from the center of the suction plate 20, and a rectangular corner piece 222 provided at the tip of the shaft 221. The base end 223 of the shaft 221 is crushed after being inserted into the through hole 202 formed in the center of the suction plate 20 and the through hole 341 formed in the mounting piece 34. As a result, the male member 22 is fixed to the suction plate 20. The mounting piece 34 is for mounting on the main body 18, and is fixed to the suction plate 20 by brazing or the like.

The female member 24 is composed of a disc-shaped bottom plate 241 provided in the hollow portion 163 of the magnet member 16 and a pair of hook-shaped pieces 242 and 243 projecting from the peripheral edge of the bottom plate 241. ing. The hook-shaped pieces 242 and 243 are provided at positions facing each other with the center of the bottom plate 241 interposed therebetween, and are bent toward the center of the bottom plate 241 near the center thereof. Therefore, the hook-shaped pieces 242, 243 are composed of vertical pieces 246, 247 vertically protruding from the peripheral edge of the bottom plate 241, and horizontal pieces 248, 249 horizontally bent near the center. There is. The gap c between the horizontal pieces 248, 249 is formed smaller than the long side b of the square piece 222 of the male member 22 and larger than the short side d of the square piece 222. The gap a between the vertical pieces 246 and 247 is formed to be larger than the long side b of the square piece 222. The height g of the vertical pieces 246, 247 from the bottom plate 241 is formed to be larger than the thickness h of the square piece 222. When these relationships are expressed by equations, a> b> c> d ..., g> h. Therefore, when the short side d of the square piece 222 is inserted into the gap c between the horizontal pieces 248 and 249 and the hook-shaped pieces 242 and 243 are rotated by 90 degrees, for example, the square piece 222 is inserted between the hook-shaped pieces 242 and 243. It is held by and cannot be pulled out. As a result, the female member 24 and the male member 22 are fitted together.

The picking member 26 is formed in a disc shape so that it can be picked easily. The rotating shaft 262 projecting from the bottom plate 241 is inserted into an insertion hole 261 formed at the center of the knob member 26 and fixed with a screw 263. Further, the hook-shaped pieces 242, 243 are fixed to the bottom plate 241 by being fitted into the notches 244, 245 formed in the bottom plate 241. Therefore, when the knob member 26 is rotated, the bottom plate 241 and the hook-shaped pieces 242 and 243 are rotated.

Further, a mounting piece 30 for mounting on the lid 14 is fixed to the rotating shaft 262 by a retaining ring 32. Since the rotating shaft 262 is loosely inserted in the through hole 301 of the mounting piece 30, the mounting piece 30 does not hinder the rotational movement of the rotating shaft 262.

Next, the operation of the locking tool 10 will be described. The magnet member 16 is attracted to a predetermined position of the attraction plate 20 while being guided along the inner peripheral surface 203 of the projection edge 201. At this time, the female member 24 is attached to the male member 22. Subsequently, when the female member 24 is rotated about 90 degrees by the picking member 26, the male member 22 and the female member 24 are fitted together. Therefore, in this state, the magnet member 16 and the attraction plate 20 do not separate even if the locking tool 10 hits something (FIG. 4). Then, when the female member 24 is rotated by about 90 degrees by the picking member 26, the male member 22 and the female member 24 are separated from each other. Therefore, in this state, the magnet member 16 and the attraction plate 20 can be separated from each other by human power (FIG. 5).
