  As shown in FIG. 9B, the blocking portion 2a is a portion that covers the upper side of the opening h of the cylinder body 1 when the shutter 2 is in the closed position, and can be protected by blocking the key hole 4a. . When the shutter 2 is in the open position, the closing portion 2a is separated from the upper side of the opening h of the cylinder body 1, and the key hole 4a is opened to the outside to open the ignition key IK, as shown in FIG. It can be inserted.

  The fitting recess 2b is a recess capable of fitting a magnet key MK (see FIG. 11). When the magnet key MK is fitted and rotated in a predetermined direction, the shutter 2 can be swung in the same direction. ing. The fitting recess 2b has a shape that follows the outer contour of the magnet key MK, and the magnet key MK can be fitted in a preset direction. On the other hand, as shown in FIG. 11, the magnet key MK is formed by molding a grip portion (a so-called mascot portion made of resin parts) of the ignition key IK into a predetermined shape, and a plurality of magnets Ma are inserted therein. Yes.

  When the shutter 2 is in the open position or the closed position, the open position recess 2c and the close position recess 2d are fitted with a steel ball b (see FIG. 8) as a moderation means so that the moderation with respect to the shutter 2 is achieved. It is for granting. The steel ball b is inserted and assembled together with the spring S3 into a hole 1d formed in the mounting portion 1a (to be described in detail later) of the cylinder body 1, and is always upward (shutter 2 side) by the spring S3. Is being energized.

  The open position recess 2c is formed at a position where the steel ball b is inserted when the shutter 2 is in the open position, and is formed of a recess having a depth t1, as shown in FIG. On the other hand, the closing position recess 2d is formed at a position where the steel ball b is inserted when the shutter 2 is in the closing position, and is formed of a recess having a depth t2, as shown in FIG. is there.

  In the present embodiment, the depth t2 of the closing position recess 2d is set to be greater than the depth t1 of the opening position recess 2c, whereby the shutter 2 is in the closing position when it is in the closing position. Greater moderation is given than at certain times. Therefore, the operability from the open position to the closed position with respect to the shutter 2 can be improved, and the shutter 2 can be reliably held at the closed position.

  When the shutter 2 is in the closed position, the insertion hole 2e is formed of a hole into which the magnet 3a constituting the magnet lock 3 can be inserted, and the magnet 3a is inserted into the insertion hole 2e and locked with the shutter 2. The operation of the shutter 2 (operation from the closed position toward the open position) is restricted. That is, when the shutter 2 is swung from the open position to the closed position, the arrangement positions of the plurality of magnets 3a and the insertion holes 2e match each other, and as shown in FIG. The biased magnets 3a are fitted into the respective fitting holes 2e and locked, thereby locking the shutter 2.

  Thus, in order to release the lock by the magnet lock 3, as shown in FIG. 10B, the magnet key MK is fitted into the fitting recess 2b of the shutter 2, and the magnet Ma and the magnet 3a are opposed to each other. As a result, a repulsive force due to magnetic force (repulsive force between different poles) is generated between the magnets Ma and 3a, and the magnet 3a is lowered against the biasing force of the spring 3b. As a result, the magnet 3a moves downward from the insertion hole 2e and is unlocked, so that the shutter 2 is unlocked. If the magnet lock 3 is rotated in a predetermined direction with the lock released, the shutter 2 is swung from the closed position to the open position.

  Here, as shown in FIG. 5, the cylinder body 1 according to the present embodiment is integrally formed with an attachment portion 1 a capable of attaching the shutter 2 in a state where the shutter 2 can be moved between the closed position and the open position at the upper end portion thereof.
