Wherein, the rotation of the mountain portion rotating member 5 causes the locking means 4 to move from the protruding state to the state in which the locking member lad is not in the state of the hole lad, and at the same time, the protruding portion 5d is formed in accordance with the rotation of the rotating structure The recess 2b of the shutter 2 is set at the position of the end wall 2 ba or 2 bb. Moreover, the unlocking operation of 2 by the rotating member 5 will be described later. The occlusion means automatically moves the shutter 2 from the open position to the occlusion position when the ignition key IK is pulled out from the keyhole 9, and the sound is composed of: the sliding member 6, the locking means 7 and the formation A protrusion holder on the bottom surface side of the shutter 2; Further, a coil spring 13 that attaches the potential chamber 2 to the slider 6 toward the upper side is disposed at a lower portion of the slider 6, and at the lower portion of the locking means 7, the attachment means 7 is attached to the locking means 7 upward. The spiral spring 14 of the potential energy is in the initial state in which the ignition key IK is not inserted, that is, the state shown in Figs. 2 and 3 (the state in which the slider 6 and the locking means 7 are together at the rising end). Further, the locking means 7 and the projections 2c correspond to the 312XP/invention specification (supplement)/97-02/96140208 1〇 200918390 of the present invention. In the initial state, the front end edge of the locking means 7 is restricted, and the shutter is restrained to abut against the shutter 2, as shown in Fig. 2, on the slider 6: before the IK end side The insertion hole 6a, such as the _^^ switch key, can be used to make the segment portion 15 and the opening edge portion W of the insertion hole 6a, 6 one end abuts against the protrusion σ of the locking means 7... And the lowering of the ¥, and the linkage means 7 and the locking means 7 also illustrate the protection device of the above-structured cylinder lock by ^^=6. As shown in FIG. 2 and FIG. 3, in the process of entering the ignition switch key 保护 from the protection device in the initial state, the segment 15 of $ & ' a is engaged with the slider 6 : plug ==... And the ignition switch key IK - from the slider 6 strong; Γ 'Poison °P phase ^ 〇, (7) Shi b resists the spiral hand: it: potential energy and decline. As the slider 6 is lowered, the lock 7 and the 7 are also lowered. Therefore, as shown in FIG. 4 and FIG. 5, the front edge portion of the locking means 7 is in the up-and-down direction, and the closing plate 2 is closed. Slightly shaken, the 刖 if the side is on the top of the locking means 7. Here, 'the end of the slider 6 after the lowering (the contact 2c formed in the shutter 2 is abutted in FIGS. 4 and 5, the state of the figure is the state, that is, the shutter 2 is only slightly shaken, and The state of the occlusion position has not been reached). In this state, if the ignition key IK is rotated from the 〇FF position to the (10) position (refer to the figure 丨), the engine of the two-wheeled vehicle starts to start, and if the engine is rotated from the 0N position to the 0FF position, the engine will stop. . In addition, when the ignition switch key 312XP/invention manual (supplement)/97-02/96140208 11 200918390 IK is pressed (PUSH) at the 0FF position, it is disposed on the round side (not shown). The lock lever protrudes and is formed in the steering device (5), the lower side hole (four), and the steering device is locked as shown in FIG. 5, the ignition switch key ^ in the state of the rotation, in the state of rotation 6, there is a falling line == switch key Π (day zoom, as shown in the state of Figure 6, the slider can be lowered again. In this state, 'slider 6 :: r 2 is also maintained. The question board 2 is in a state of being slightly in the open position. The port 4 is not slightly shaken. Therefore, in the protection device of the present embodiment, since the pressing point is by 1 = the configuration of the steering device of the locking vehicle: the wire is strong and the same as the ignition switch and must be pressed. It can also be applied to the cylinder lock that locks to the device. Of course, if you want to = a cylinder lock without a locking position (not limited to a two-wheeled vehicle), the sliding member 6 in Figure 5 is further lowered. Then, it is not necessary to: If the ignition key ίκ is pulled out from the keyhole 9, the sliding spiral The additional potential energy of the spring 13 is directed upwards. The lock segment 7 passes over the intermediate plate 2 on it, so that it is raised by the additional potential energy of the rotary spring 14. ^ ', the card of the unlocking means 7 The human body can be removed, and then the brake plate 2 is released. Therefore, the torque cage and the protrusion 2C are engaged to the occlusion position; the figure is twisted and the force is φ. In the state in which the shutter 2 is in the closed position, the locking means 4 is in the state of the box 丨 (4) = and is formed to abut the section 2a of the shutter 2. Thus, the 312XP/invention specification ( Replenishment) /97·〇2/9614〇2〇8 12 200918390 It can be restricted from the blocking position of the shutter 2 to the open position, and the shutter 2 becomes locked. Therefore, When the ignition switch key IK is pulled out from the keyhole 9, the shutter 2 can be automatically swung to the blocking position to block the keyhole 9, because It is not necessary to use the operation of the shutter 2 as a separate operation unit, and the occlusion operation of the shutter 2 is not required, and the anti-theft effect can be improved. Also, the ignition key ικ is pulled out from the keyhole 9. The shutter mechanism 2 is widely mechanically implemented. Therefore, it is not necessary to detect the precision parts such as the ignition switch key by electric or magnetic gas, and the manufacturing cost can be reduced and can be reduced. To simplify the maintenance, etc. As described above, in order to swing the locked shutter 2 to the open position in the occlusion position, first, as shown in FIG. 1A, the magnetic key MK is inserted into the hole lbb of the cover ib, and the magnet Ma is used. The locking of the rotating member 5 is released. When the magnetic key MK is rotated in the right direction from this state, the rotating member 5 reaches the state shown in Fig. 12 from the state shown in Fig. 11, as shown in Fig. 3, the mountain L The portion 5c presses the locking means 4 so as to be immersed in the hole lad. Thereby, the locking of the shutter 2 can be released. Thus, the locking means 4 is used to unlock the lock. The magnetic recording key MK rotates, and when the rotating member 5 also rotates, (4) 2, The portion 5d presses the end wall of the recess 2b, and the shutter 2 and the member 5 are interlocked to be shaken to the open position. When the shutter 2 reaches the open position, the locking means 7 is provided by the additional potential of the coil spring 14 It is shown that the end portion of the lock period 7 and the front end of the shutter 2 are in an initial state in which the portion abuts (that is, the limit == 312XP/invention specification (supplement)/97-02/96140208 200918390 the shaking action of the blocking position The state). After that, as shown in the opposite direction of the magnetic cousin (left side; 吏 state. The above completes a series of techniques, the magnetic record-like shape of the r-shaped can be two brothers, the household, 16 forms, but this The invention is not limited to this real lock t: the locked hand of the occluded state of the board (4) The sweet spoon unlocking hand & and other structures may be used instead. Further, if the wm ^ T j (four) plate is automatically moved from the open position when the ignition switch key is pulled out from the key # hole, the occlusion means gas or magnetic gas of the mechanical structure of the present embodiment is detected whether or not the ignition is pulled out. Switch the key and use the horse = other, drive means, etc. to move the shutter, so it is also possible. Further, the middle closed plate may be configured to be swingable between the open position and the closed position, but may be configured to slide between the positions.
