Note that the stopper plate 3 is pulled upward by the magnetic force of the magnet 21 and the cover 41 is pushed up by the stopper plate 3 so that the cover 41 also tries to move upward, but the second engaging recesses 55 and 56 are formed. Since the lower ends 55b and 56b of the cover 41 are pressed into engagement with the engagement claws (engagement protrusions) 31 and 32 of the case 12, the regulation position of the cover 41 is held.

The tip 3b of the stopper plate 3 contacts the lower ends 43a and 44a of the cover 41, and is located between the locking projection 26 and the locking projection 27. When the door D is to be closed, the locking projection 27 is locked to the edge 5a of the locking opening 5 of the stopper plate 3, so that the door D cannot be closed. In this way, the door stopper 11 can completely prevent the door D from rotating in the opening/closing direction by the locking projection 26 and the locking projection 27. That is, the tip 3b of the stopper plate 3 is separated from the bottom wall 25 against the magnetic force of the magnet 21, and is in the locking position (regulating position) where it is locked by the locking projection 27 of the locking member 40. , It is impossible to enter/exit through the gap H. In the cover 41, the lower end 42a of the front plate 42, the lower end 43a of the left face plate 43, and the lower end 44a of the right face plate 44 are located below the bottom wall 25 of the case 12 (regulation position), and are engaged with the bottom wall 25 of the case 12. The gap H between the apex 27C of the stop projection 27 is closed.

As shown in FIG. 8D, when the door D rotates in the opening direction A, the stopper plate 3 prevents the door D from rotating because the tip 3b of the stopper plate 3 comes into contact with the locking projection 26. It will not open any further. When the door D rotates in the closing direction B, the edge 5a of the locking opening 5 of the stopper plate 3 abuts on the locking projection 27, so that the stopper plate 3 prevents the door D from rotating. No more closing. In this manner, the door D is prevented from rotating in the opening direction A and the closing direction B by the stopper plate 3, and is kept in the open state. The stopper plate 3 is pulled upward by the magnetic force of the magnet 21, and the cover 41 also tries to move upward, but the lower ends 55b and 56b of the second engaging recesses 55 and 56 are engaged with the cover 41. Since the claws (engaging protrusions) 31 and 32 are pressed into engagement with each other, the restricting position of the case 12 is held. Further, the second engaging recesses 55, 56 are formed longer than the first engaging recesses 53, 54, but may be formed shorter like the first engaging recesses 53, 54. .. In this case, the cover 41 is positioned in the case 12 when the second engagement recesses 55, 56 engage with the engagement claws (engagement protrusions) 31, 32 of the central wall 15.

As shown in FIG. 8E, the cover 41 is pulled up to engage the first engagement recesses 53 and 54 with the engagement claws (engagement protrusions) 31 and 32 of the case 12. The lower end 42a of the front plate 42, the lower end 43a of the left face plate 43, and the lower end 44a of the right face plate 44 are located above the bottom wall 25 of the case 12. In the cover 41, the lower end 42a of the front plate 42, the lower end 43a of the left face plate 43, and the lower end 44a of the right face plate 44 are located above the bottom wall 25 of the case 12 (non-regulated position), and The gap H between the apex 27C of the locking projection 27 is opened. The top of the tip 3b of the stopper plate 3 is attracted by the magnetic force of the magnet 21 and abuts on the bottom wall 25 of the case 12. The locking projection 27 is released from the locking opening 5 of the stopper plate 3. The stopper plate 3 moves to the non-locking position with the tip 3b disengaged from the locking projection 27, does not block the rotation of the door D in the closing direction B, and can close the door D.

The door D can be closed because rotation in the opening direction A is blocked by the stopper plate 3 but rotation in the closing direction B is not blocked by the stopper plate 3. When the door D is closed, the tip 3b of the stopper plate 3 advances into the locking member 40 through the gap H between the bottom wall 25 and the locking projection 27, and as shown in FIG. It is closed without blocking rotation. Since the taper 27B is formed on the locking projection 27 on the advance side of the locking member 40, the tip 3b of the stopper plate 3 is smoothly guided to the gap H.
