  However, when the above-described electronic key corresponding only to electronic verification is used in the conventional steering lock device, it is difficult to realize a mechanical steering lock mechanism because no mechanical key is used for the electronic key. .

  In addition, in order to comply with European regulations (ECE.Reg18.02 5.9.2 “Unauthorized use prevention device”), an ignition including an electronic key is required when the lock bar is operated to limit the movement of the steering shaft. There is a legal restriction that the lock bar cannot be operated unless the key is pulled out from the key cylinder by a specified distance (2 mm) or more.

  Accordingly, an object of the present invention is to provide a steering lock device capable of realizing a mechanical steering lock mechanism using an electronic key having no mechanical key.

It is preferable to be formed as described above. The shape of the engagement groove 2a is the front of the key insertion direction (upper right direction in FIG. 2) so that the key hook can be easily detached from the engagement groove 2a when the electronic key 2 is in the off position. The surface in the right direction in FIG. 3 is formed to have an inclined surface inclined forward in the key insertion direction. The number of the engaging grooves 2a may be one or plural. The number of engagement grooves 2a in this embodiment is set to two.

  The rotor 3 has a key cylinder 3a into which the electronic key 2 is inserted, and rotates according to a rotation operation performed on the electronic key 2 inserted into the key cylinder 3a. Conventionally, the rotation operation of the electronic key 2 has been performed within the range of the rotation position of 90 degrees or more and less than 180 degrees to the right from the initial position that is the insertion / removal position of the electronic key 2 with the key insertion direction as the rotation axis. The same applies to this embodiment. In the rotation operation of the electronic key 2, the rotation position of the electronic key 2 is an OFF (OFF) position, an accessory (ACC) position, an ON (ON) position, or a start (START) position according to the rotation position. Generally, they are divided in order. In the present embodiment, the initial position corresponds to the off position, and the lock release position corresponds to the rotational position behind the accessory position.

  Further, as shown in FIG. 2, the rotor 3 has elements necessary for the key cylinder 3a, the component arrangement hole 3b, and the rotor 3, and is provided with holes, notches, protrusions and the like for forming them. It is formed in a cylindrical shape.

  The lock body mainly includes a rotor cylinder 9a, a lock bar housing 9b, and a locking lever housing 9c. The rotor cylinder 9 a is formed in a cylindrical shape having an inner diameter similar to the outer diameter of the rotor 3. The lock bar housing 9b has a C-shape that partially surrounds the steering shaft in front of the key insertion direction of the rotor cylinder 9a, and is a lock that serves as the limiting member 5 of the present embodiment. In addition to the bar, the slider 10, the lock holder, the compression lock spring, and the restriction releasing cam 6 are formed in a built-in shape. The locking lever housing 9c is formed in a shape to which a locking lever that becomes the fixing member 7 of this embodiment, a spring that becomes the elastic member of this embodiment, and a plate cover are attached.

  The electronic collator 4 receives the ID code of the electronic key 2 and collates it with the ID code stored therein. This electronic collator 4 is attached to the side of the rotor cylinder 9a of the lock body, and permits the rotation of the rotor 3 only when a desired collation result is obtained by electronic collation of the ID code of the electronic key 2. It is formed to do.

  The limiting member 5 is a member that engages with the steering shaft to limit the rotation of the steering shaft. The limiting member 5 of the present embodiment is preferably a lock bar that moves in a direction opposite to the key insertion direction, which is a direction to release the rotation limitation of the steering shaft.

  The lock bar which is the restricting member 5 is used in combination with a slider 10, a lock holder and a compression lock spring. The slider 10 is preferably a member that slides back and forth in the key insertion direction together with the lock bar by mutual engagement with the lock bar serving as the limiting member 5. The lock holder has a slide rail that slides the slider 10 back and forth in the key insertion direction. The compression lock spring is a coil spring arranged in parallel to the key insertion direction inside the lock bar housing 9b, and is locked via the slider 10 in the key insertion direction, which is the direction that limits the rotation of the steering shaft. The bar (the limiting member 5) is pressed.

  The restriction release cam 6 is formed to move the restriction member 5 to a predetermined position when the electronic key 2 is rotated from the initial position to the lock release position in conjunction with the rotation of the rotor 3. Here, the initial position of the electronic key 2 is an off position where the insertion / removal operation of the electronic key 2 is performed, and the unlocking position is a rotation position ahead of the accessory position in the present embodiment. Further, the predetermined position of the limiting member 5 is a position at which the rotation limitation of the steering shaft is released.

  Here, as shown in FIG. 2, the restriction releasing cam 6 of the present embodiment is arranged on a concentric shaft with the rotor 3, and rotates together with the rotor 3 using the rotation of the engaging rotor 3 as a drive source. A cylindrical cam is preferred. In this case, the restriction releasing cam 6 has a cam groove formed in a slope shape on the side surface of the cylindrical cam, and a protrusion provided on a slider 10 (a member connected to the limiting member 5) connected to the limiting member 5. It is preferable that the limiting member 5 is formed to move in the direction opposite to the key insertion direction by moving the portion along the cam groove.

  The fixing member 7 is a member that fixes the restriction member 5 that has been moved to a predetermined position by the restriction release cam 6 at a predetermined position. The predetermined position is a position where the restriction of the rotation of the steering shaft in the restricting member 5 is released as described above. That is, the fixing member 7 is a member that fixes the lock bar (the limiting member 5) that moves in the direction opposite to the key insertion direction via the slider 10 by the restriction releasing cam 6 to a position (predetermined position) close to the rotor 3. is there.

  Here, as shown in FIG. 2, the fixing member 7 is preferably a locking lever having a hook portion at one end. In this embodiment, the hook portion of the fixing member 7 is formed so as to engage with an engaging portion that is formed to project horizontally from the slider 10 (an interlocking element that interlocks with the limiting member 5) that interlocks with the lock bar. Yes. In other embodiments, the engaging portion may be the limiting member 5, the rotor 3, or an interlocking element that interlocks with the rotor 3.

  Moreover, it is preferable that the fixing member 7 of this embodiment is arrange | positioned in parallel with the key insertion direction between the rotor 3 and the limitation member 5 in the longitudinal direction. At that time, the hook portion of the fixing member 7 of the present embodiment is directed to the restricting member 5 side, and the slider 10 (the interlocking element of the restricting member 5) that moves in the opposite direction of the key insertion direction in the engageable state is engaged. The fixing member 7 of the present embodiment is formed so as to engage with the joint portion. The engageable state refers to two engagement states of the hook portion of the fixing member 7 and the engagement portion of the slider 10 selected by the release member 8, that is, among the engageable state and the disengaged state. One state.

  Furthermore, it is preferable that the fixing member 7 of the present embodiment is formed so that a rotation support shaft provided in the vicinity of the center of the fixing member 7 is movable outward in the direction orthogonal to the key insertion direction. In this case, the locking lever housing 9c of the lock body includes a fixing member 7 arrangement hole into which the fixing member 7 is inserted, two notches facing in the horizontal direction in the fixing member 7 arrangement hole, and the fixing member 7 arrangement. The hole has an elastic member disposition hole that houses the elastic member. The two notches extend in a direction orthogonal to the key insertion direction, and preferably support the rotation support shaft of the fixing member 7 so as to be movable outward in the direction orthogonal to the key insertion direction. .

  The elastic member is a member that urges a hook portion provided at one end of the fixing member 7 to the outside in the direction orthogonal to the key insertion direction. The elastic member is not particularly specified, but is preferably a coil spring from the relationship between economy and elastic force. In this case, the elastic member is disposed between the other end of the fixing member 7 and the plate cover, and the other end of the fixing member 7 is urged inward in the direction orthogonal to the key insertion direction, thereby rotating the rotation support shaft. The hook part is urged to the outside in the direction orthogonal to the key insertion direction via.

  The release member 8 is a member that releases the fixation performed by the fixing member 7 to the restriction member 5 when a predetermined condition is satisfied. The predetermined conditions are the following two.

  The first condition is that the electronic key 2 is rotated from an unlock position (for example, an accessory position) to an initial position (for example, an off position). That is, the first condition is a rotation operation of the electronic key 2 until the engine of the automobile including the steering lock device 1 of the present embodiment is shifted from the operating state to the stopped state and the electronic key 2 is removed. Since the rotation operation from the initial position to the unlocking position is the reverse rotation operation under the first condition, the first condition is not satisfied.

  The second condition is that after satisfying the first condition, the electronic key 2 is extracted from the key cylinder 3a of the rotor 3 by a specified distance. The specified distance can be set to an arbitrary distance, but in order to comply with European regulations, the specified distance from the end face of the key cylinder 3a with which the electronic key 2 abuts is set to 2 mm or more. The electronic key 2 is extracted in the direction opposite to the key insertion direction.

  Here, the release member 8 of the present embodiment is formed so as to remove the engaging portion of the slider 10 from the hook portion of the fixing member 7 by operating the lever on the fixing member 7 based on the insertion / removal operation of the electronic key 2. It is preferable that Thereby, the release member 8 can release the engagement that is the fixation by the fixing member 7. Since there are various methods for operating the fixing member 7 with the release member 8 of the present embodiment, various shapes and arrangements of the release member 8 can be considered depending on the lever operation method. The following can be considered.

  As shown in FIG. 4, the release member 8 of the present embodiment is preferably a slide piece whose longitudinal section is formed in an umbrella-shaped or mushroom-shaped block shape. In this case, the release member 8 is arranged in the component arrangement hole 3b having a reverse convex cross section penetrating in the direction orthogonal to the key insertion direction in the rotor 3, and the release member 8 corresponds to the insertion / removal operation of the electronic key 2 in the key insertion direction. It is formed so as to move outward or inward in the orthogonal direction. The top surface of the umbrella portion of the release member 8 has a curved surface similar to the cylindrical side surface 3 c of the rotor 3, and when the handle portion of the release member 8 is arranged in the component arrangement hole 3 b of the rotor 3, It protrudes downward (inward) from the component placement hole 3b and is formed to a length that contacts the electronic key 2 inserted into the key cylinder 3a of the rotor 3.

  Further, as described above, when the electronic key 2 is inserted, the release member 8 moves to the outside in the direction orthogonal to the key insertion direction. Therefore, as shown in FIG. 5B to FIG. By using this, the other end of the fixing member 7 is moved to the outside in the orthogonal direction of the key insertion direction, and the hook portion is moved inward in the orthogonal direction around the rotation support shaft of the fixing member 7. It is preferable that the portion is formed so as to be engageable with the engaging portion of the slider 10 (the interlocking element of the limiting member 5). Further, as described above, when the electronic key 2 is extracted, the release member 8 moves inward in the direction orthogonal to the key insertion direction, so that as shown in FIGS. 6B to 5B. While using the movement and the elastic force of the elastic member, the other end of the fixing member 7 is moved inward in the orthogonal direction, and the hook portion is moved outward in the orthogonal direction around the rotation support shaft. It is preferable to be formed so as to release the engagement of the parts.

  Next, a fixing mechanism by the fixing member 7 and a releasing mechanism by the releasing member 8 of the steering lock device 1 of the first embodiment will be described with reference to FIGS.

  Before the electronic key 2 is inserted, as shown in FIGS. 5A and 5B, the slide piece (release member 8) is perpendicular to the key insertion direction (left direction in the figure) (up and down direction in the figure). It moves inward and the handle portion of the slide piece is exposed on the key cylinder 3 a of the rotor 3. Moreover, since the slide piece (release member 8) of the locking lever (fixing member 7) has not moved outward in the direction perpendicular to the key insertion direction, the hook portion of the locking lever (fixing member 7) has moved outward. Yes. That is, the locking lever (fixing member 7) is in a disengaged state. On the other hand, the protrusion of the slider 10 that engages with the cam groove of the limit release cam 6 is located farthest from the rotor 3 as shown in FIG.・ It is in the limit position to engage with the shaft.

  In the state where the regular electronic key 2 is inserted (the initial position (off position) of the electronic key 2), as shown in FIGS. 6A and 6B, the slide piece exposed to the key cylinder 3a of the rotor 3 The handle portion contacts the electronic key 2, and the slide piece (release member 8) moves to the outside in the direction orthogonal to the key insertion direction. Moreover, since the slide piece (release member 8) of the locking lever (fixing member 7) has moved to the outside in the direction perpendicular to the key insertion direction, the hook portion of the locking lever (fixing member 7) moves to the inside thereof. That is, the locking lever (fixing member 7) is in an engageable state. The electronic collator 4 shown in FIG. 2 permits the rotation of the rotor 3 when the regular electronic key 2 is inserted. Since the rotor 3 does not rotate at this point, there is no change in the protruding portions of the limit release cam 6 and the slider 10 as shown in FIG. 6C.

  7A and 7B show a state in which the electronic key 2 is rotated about the key insertion direction by the operator and the rotor 3 is rotated until just before the engagement of the fixing member 7 with the rotation. As described above, the contact surface with the end of the locking lever (fixing member 7) changes from the top surface of the umbrella portion of the slide piece (release member 8) as shown in FIG. Since the cylindrical side surface 3 c of the rotor 3 is smoothly curved, the state of the locking lever (fixing member 7) does not change until the hook portion comes into contact with the engaging portion of the slider 10. On the other hand, as shown in FIG. 7C, the restriction releasing cam 6 interlocked with the rotor 3 uses the cam groove to move the protruding portion of the slider 10 in the direction opposite to the key insertion direction (right direction in the figure). . As a result, the lock bar (the limiting member 5) connected to the slider 10 moves to the vicinity of a predetermined position where the engagement with the steering shaft is released.

  When the fixing member 7 is engaged, as shown in FIGS. 8A and 8B, when the hook portion of the locking lever (one end of the fixing member 7) is engaged with the engaging portion of the slider 10, Using the contact point between the other end of the fixing member 7 and the cylindrical side surface 3c (other member) of the rotor 3 as a fulcrum, the hook portion is engaged with the engaging portion of the slider 10 while moving outward in the direction perpendicular to the key insertion direction. Match. At that time, the fixing member 7 is supported by the two notches shown in FIG. 2 so as to be movable outwardly in the direction perpendicular to the key insertion direction. Moves to the outside of the direction perpendicular to the key insertion direction together with the hook portion.

  The cylindrical side surface 3c (other member) of the rotor 3 that contacts the other end of the fixing member 7 only when the hook portion of the fixing member 7 engages with the engaging portion of the slider 10 is the inner side in the direction perpendicular to the key insertion direction. When the structure has such a structure as to move, the rotation support shaft of the fixing member 7 does not need to move to the outside in the direction orthogonal to the key insertion direction together with the hook portion.

  On the other hand, as shown in FIG. 8C, the restriction releasing cam 6 interlocked with the rotor 3 uses the cam groove to move the protruding portion of the slider 10 to the end in the direction opposite to the key insertion direction. As a result, the lock bar (the limiting member 5) connected to the slider 10 moves to a predetermined position where the engagement with the steering shaft is released.

  In the state where the fixing member 7 has finished engaging with the engaging portion (the lock release position (accessory position) of the electronic key 2), as shown in FIGS. 9A and 9B, the hook portion of the locking lever Since (one end of the fixing member 7) is engaged with the engaging portion of the slider 10, the locking lever (fixing member 7) fixes the lock bar (the limiting member 5) via the slider 10. Since the cam groove of the limit release cam 6 has also moved the engaging portion of the slider 10 to its end, the limit release cam 6 does not move the lock bar (limit member 5) via the slider 10. Since these series of operations are irreversible, even if the electronic key 2 is rotated in the opposite direction from the state shown in FIG. 9A to the state shown in FIG. 5A, the locking lever (fixing member 7) is shown in FIG. The engagement state is maintained without changing in the order of 5 (b).

  When the electronic key 2 reversely rotates from the unlock position (accessory position) to the initial position (off position), the engaging portion of the slider 10 connected to the lock bar (restricting member 5) and the hook of the locking lever (fixing member 7). The electronic key 2 rotates from the state shown in FIG. 9 (a) to the state shown in FIG. 5 (b) while maintaining the engagement with the portion as shown in FIG. 9 (b). At that time, since the rotor 3 also rotates in the opposite direction, the contact surface with the other end of the locking lever (fixing member 7) changes from the cylindrical side surface 3c of the rotor 3 to the top surface of the umbrella portion of the slide piece (release member 8). To do. When the electronic key 2 is pulled out beyond a specified distance, the slide piece (release member 8) moves inward in the direction perpendicular to the key insertion direction together with the other end of the locking lever (fixing member 7). The locking lever (fixing member 7) moves to the outside in the direction perpendicular to the key insertion direction around the rotation support shaft 7). As a result, the engagement relationship between the engagement portion of the slider 10 and the hook portion of the locking lever (fixing member 7) returns from the state shown in FIG. 9B to the state shown in FIG. 4B, and the engagement is released. . Accordingly, the protruding portion of the slider 10 also returns to the state shown in FIG.

  Next, the operation of the steering lock device 1 of the first embodiment will be described.

  In the steering lock device 1 of the first embodiment, as shown in the order of FIGS. 5 (b) to 6 (b) and the order of FIGS. 5 (c) to 6 (c), the key cylinder of the rotor 3 is used. A restriction release cam 6 interlocked with the rotor 3 that rotates in response to a rotation operation performed on the electronic key 2 inserted in 3a moves the lock bar (restriction member 5) to a predetermined position via the slider 10. Further, as shown in FIG. 6B, the lock bar (the limiting member 5) that has moved to the predetermined position is fixed at the predetermined position by the locking lever (fixing member 7). Then, as shown in the order of FIG. 9B and FIG. 4B, the release member 8 is fixed to the restricting member 5 when the electronic key 2 is removed from the key cylinder 3a of the rotor 3 by a specified distance. Release the fixing you are doing for. That is, when the restriction member 5 is mechanically moved by the restriction release cam 6 interlocked with the rotor 3 that rotates together with the electronic key 2 and the electronic key 2 is pulled out by a specified distance, the restriction member 5 is fixed. Since the restriction member 5 is engaged with the steering shaft, the restriction member 5 can be mechanically engaged with the steering shaft according to European regulations.

  Further, in the steering lock device 1 of the present embodiment, a lock bar that moves in the direction opposite to the key insertion direction is adopted as the limiting member 5, and a slider that interlocks with the lock bar (the limiting member 5) is used as the fixing member 7. The locking lever which has a hook part engaged with the engaging part formed in 10 (interlocking element) is employ | adopted. Further, the release member 8 performs a lever operation on the fixing member 7 based on the inserting / removing operation of the electronic key 2 to remove the engaging portion from the hook portion of the fixing member 7, thereby engaging with the fixing member 7. It is formed to release. As a result, a hook mechanism having a simple structure can be formed by the fixing member 7 and the releasing member 8 described above, and the fixing and releasing from the predetermined position with respect to the control member can be mechanically and easily performed by the hook mechanism. Can be done automatically.

  Further, in the steering lock device 1 of the present embodiment, as shown in FIGS. 4B to 9B, the longitudinal direction of the fixing member 7 is parallel to the key insertion direction, and the hook portion is the limiting member 5. The release member 8 is preferably a slide piece that moves to the outside or the inside in the orthogonal direction in accordance with the insertion / removal operation of the electronic key 2. Thereby, a hook mechanism with a simple structure and a small number of parts can be realized by the fixing member 7 and the release member 8.

  Further, in the steering lock device 1 of the present embodiment, as shown in FIG. 8B, the rotation support shaft of the fixing member 7 is formed so as to be movable outward in the direction perpendicular to the key insertion direction. It is preferable to move outward in the orthogonal direction when engaged. Thereby, it can be made to engage, without moving the part which contact | abuts the other end of the fixing member 7 to the inner side of an orthogonal direction at the time of engagement of a hook part and an engaging part.

  Further, in the steering lock device 1 of the present embodiment, it is preferable that the restriction release cam 6 is a cylindrical cam that moves the restriction member 5 in the direction opposite to the key insertion direction using the cam groove. Thereby, the structure of the restriction release cam 6 can be simplified.

  Next, the steering lock device 1 of the second embodiment will be described.

  As in the first embodiment, the steering lock device 1 according to the second embodiment includes an electronic key 2, a rotor 3, an electronic collator 4, a restriction member 5, a restriction release cam 6, a fixing member 7, and a release member 8. ing. The difference between the second embodiment and the first embodiment is that, as shown in FIG. 10A, a part of the hook mechanism mainly composed of the fixing member 7, the elastic member, the release member 8 and the rotor 3 is changed. Other structures are the same as those in the first embodiment.

  As shown in FIG. 10A, the locking lever (fixing member 7) is arranged between the rotor 3 and the restricting member 5 so that the longitudinal direction thereof is parallel to the key insertion direction, as in the first embodiment. Yes. However, unlike the first embodiment, the hook portion provided at one end of the locking lever (fixing member 7) is arranged so as to face the rotor 3 side. Further, the locking lever (fixing member 7) is attached to the slider 10 that is interlocked with the limiting member 5, and is thus configured to move in the direction opposite to the key insertion direction in conjunction with the limiting member 5.

  As shown in FIG. 10A, the elastic member is arranged so as to urge the hook portion of the fixing member 7 in the direction perpendicular to the key insertion direction, unlike the first embodiment. The point that it is preferable to employ a coil spring as the elastic member is the same as in the first embodiment.

  As shown in FIGS. 10A and 10B, the rotor 3 has a fixed engagement disk as a part of the engagement portion. This fixed engagement disk is an element that engages with the hook portion of the fixed member 7 that has moved in the direction opposite to the key insertion direction. Then, this fixed engagement disk maintains the engagement with the hook portion of the fixed member 7 at a rotational position other than the initial position of the electronic key 2 where the electronic key 2 is inserted and removed. As shown in FIG. 4, the fan is formed in a fan shape when viewed from the key insertion direction.

  The release member 8 also serves as a part of a key hook disposed so as to be interlocked with the rotation of the rotor 3 on the side of the key cylinder 3a. This key hook is formed in such a shape that one end thereof engages with the engaging groove 2 a of the electronic key 2 in order to prevent the electronic key 2 from being pulled out at a rotational position other than the initial position of the electronic key 2. The release member 8 is formed using this key hook.

  That is, the other end of the key hook serving as the release member 8 is arranged on the same circumference as the fixed engagement disk of the rotor 3. Further, as shown in FIG. 14, the other end of the key hook serving as the release member 8 is formed such that when the electronic key 2 is pulled out at the initial position of the electronic key 2, it moves inward in the orthogonal direction. ing.

  The other end of the key hook is used as a moving engagement portion that releases engagement with the hook portion of the fixing member 7. This moving engagement portion is used as the remaining portion of the engagement portion formed in the rotor 3.

  Next, the fixing mechanism by the fixing member 7 and the releasing mechanism by the releasing member 8 of the steering lock device 1 of the second embodiment will be described with reference to FIGS. 10 to 14.

  In the state in which the regular electronic key 2 is inserted (the initial position (off position) of the electronic key 2), the key hook is engaged with the engaging groove 2a of the electronic key 2 as shown in FIGS. The other end moves to the outside in the orthogonal direction (vertical direction in the figure) of the key insertion direction (left direction in the figure). Thereby, a locking lever (fixing member 7) will be in an engagement possible state. As in the first embodiment, the electronic collator 4 shown in FIG. 2 permits the rotation of the rotor 3 when the regular electronic key 2 is inserted. At this time, the rotor 3 is not rotating. Therefore, there is no movement of the restriction releasing cam 6 and the protruding portion of the slider 10, and the lock bar (the restricting member 5) is at the restricting position where the lock bar (the restricting member 5) is engaged with the steering shaft.

  When the electronic key 2 is rotated by the operator and the rotor 3 is rotated until just before the engagement of the fixing member 7 with the rotation of the electronic key 2, as shown in FIGS. The restriction release cam 6 to be used moves the protruding portion of the slider 10 in the direction opposite to the key insertion direction (right direction in the figure) using the cam groove. As a result, the lock bar (the limiting member 5) connected to the slider 10 moves to the vicinity of a predetermined position where the engagement with the steering shaft is released. On the other hand, the locking lever (fixing member 7) moves in the direction opposite to the key insertion direction (right direction in the figure) in conjunction with the slider 10, so that the hook portion of the locking lever (fixing member 7) is fixedly engaged with the rotor 3. Proximity until just before contacting the disc.

  In a state where the locking lever (fixing member 7) is engaged, as shown in FIGS. 12 (a) and 12 (b), the restriction releasing cam 6 interlocked with the rotor 3 forms the protruding portion of the slider 10 in FIG. 12 (b). It is moved further in the direction opposite to the key insertion direction than in the state of. And when the hook part (one end of the fixing member 7) of the locking lever interlocked with the slider 10 is engaged with the fixed engagement disk of the rotor 3, the rotation support shaft of the locking lever (fixing member 7) is used as the center of rotation. The hook portion engages with the fixed engagement disk of the rotor 3 while moving outward in the direction perpendicular to the key insertion direction.

  In a state where the fixing member 7 has finished engaging with the engaging portion (the lock release position (accessory position) of the electronic key 2), as shown in FIGS. 13 (a) and 13 (b), it is connected to the slider 10. The lock bar (the limiting member 5) moves to a predetermined position where the engagement with the steering shaft is released. Further, since the hook portion of the locking lever (one end of the fixing member 7) is engaged with the fixed engagement disk of the rotor 3, the locking lever (fixing member 7) is connected to the lock bar (the limiting member 5) via the slider 10. ) Is fixed. Since the cam groove of the limit release cam 6 has also moved the engaging portion of the slider 10 to its end, the limit release cam 6 does not move the lock bar (limit member 5) via the slider 10. Since these series of operations are irreversible, even if the electronic key 2 is rotated in the opposite direction from the state shown in FIG. 13 (b) to FIG. 10 (b), the locking lever (fixing member 7) is shown in FIG. 13 (a). The engaged state is maintained without changing in the order of 10 (a).

  When the electronic key 2 reversely rotates from the unlock position (accessory position) shown in FIG. 13 to the initial position (off position) shown in FIG. 14, the fixed engagement of the rotor 3 connected to the lock bar (restricting member 5). The electronic key 2 rotates from the state shown in FIG. 13B to the state shown in FIG. 14 while maintaining the engagement between the disk and the hook portion of the locking lever (fixing member 7) as shown in FIG. At that time, since the rotor 3 also rotates in the opposite direction together with the reverse rotation of the electronic key 2, the engagement portion of the hook portion of the locking lever (fixing member 7) is moved from the fixed engagement disk of the rotor 3 to the moving engagement portion of the key hook. It changes to (release member 8). When the electronic key 2 is extracted beyond the specified distance, the key hook moving engagement portion (release member 8) moves inward in the direction perpendicular to the key insertion direction and is separated from the hook portion of the locking lever (fixing member 7). To do. Thereby, the engagement of the hook portion of the locking lever (fixing member 7) returns from the state shown in FIG. 14 to FIG. 10A, and the engagement is released. Accordingly, the lock bar (restricting member 5) linked to the slider 10 also returns to the state shown in FIG.

  Next, the operation of the steering lock device 1 of the second embodiment will be described.

  In the steering lock device 1 according to the second embodiment, as shown in FIG. 10A, the fixing member 7 is formed so as to be interlocked with the limiting member 5 that moves in the direction opposite to the key insertion direction. 3 fixed engagement discs. The release member 8 also serves as a key hook having an end portion with a moving engagement portion arranged on the same circumference as the fixed engagement disk of the rotor 3. Therefore, a hook mechanism with a simple structure and a small number of parts can be realized by the fixing member 7 and the release member 8.

  That is, according to the steering lock device 1 of the first and second embodiments, the restriction member 5 is mechanically moved by the restriction release cam 6 interlocked with the rotor 3 that rotates together with the electronic key 2, and the electronic key Since the restriction member 5 is unlocked and the restriction member 5 is engaged with the steering shaft when 2 is pulled out by a specified distance, the restriction member 5 is mechanically engaged with the steering shaft according to European regulations. Various actions such as being able to be combined are generated. As a result, there is an effect that a mechanical steering lock mechanism can be realized by using the electronic key 2 having no mechanical key while complying with European laws and regulations.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed.
