On the other hand, when the front end of the lock plate 36 is turned upward by the urging force as described above, the downward pressing of the switch 96A by the front side portion of the lock plate 36 is released. As a result, the switch 96 </ b> A protrudes upward from the key warning switch 96 by the urging force and is accommodated in the accommodating cylinder 22.

  The key warning switch 96 is connected to the control device 84. A warning device 98 is connected to the control device 84, and the warning device 98 can emit a warning (for example, a warning sound) under the control of the control device 84. A detection device 100 is connected to the control device 84, and the detection device 100 can detect opening and closing of a door (not shown) of the vehicle.

  Next, the operation of the present embodiment will be described.

  In the steering lock device 10 having the above-described configuration, the key rotor 28 and the camshaft 42 are disposed at the “LOCK” position, and the lock bar 70 is rearward from the fixed piece 18 (the holding cylinder 68 of the lock holder 16) of the lock body main body 14. The rotation of the steering shaft and the steering wheel is locked by protruding to the side and being engaged with the steering shaft.

  Further, when the ignition key 32 is inserted into the insertion hole 30 of the key rotor 28 and rotated, the key rotor 28 and the camshaft 42 resist the urging force of the return spring in the “ACC” position, “ON” position, and “ The ignition switch 76 is operated by being rotated to the “START” position.

  When the key rotor 28 and the camshaft 42 are rotated from the “LOCK” position to the “ACC” position, the inclined surface 52 of the camshaft 42 (outer cylinder 44) is rotated to push the moving projection 60 of the slider 58 forward. Thus, the slider 58 and the lock bar 70 are moved to the front side against the urging force of the compression spring 74. For this reason, when the key rotor 28 and the camshaft 42 are rotated to the “ACC” position, the lock bar 70 is released from protruding from the fixed piece 18 of the lock body main body 14, and the lock bar 70 is moved to the steering shaft. The engagement is released. Thereby, rotation of a steering shaft and a steering wheel is permitted.

  Further, when the key rotor 28 and the camshaft 42 are rotated from the “LOCK” position to the “ACC” position, the slider 58 is moved to the front side as described above, so that the rear end of the lock plate 36 is biased. As a result, the engagement protrusion 64 of the slider 58 gets over the rear end of the lock plate 36. Thus, the engagement protrusion 64 of the slider 58 is engaged with the rear end of the lock plate 36, and the rearward movement of the slider 58 and the lock bar 70 by the urging force of the compression spring 74 is locked.

  In addition, when the key rotor 28 and the camshaft 42 are disposed within the range of the “START” position from the “ACC” position via the “ON” position, the front end of the lock plate 36 abuts on the circumferential surface of the key rotor 28. Thus, the downward rotation of the rear end of the lock plate 36 is restricted, and the state in which the engagement protrusion 64 of the slider 58 is engaged with the rear end of the lock plate 36 is maintained. Further, when the key rotor 28 and the camshaft 42 are rotated from the “ACC” position to the “LOCK” position, the ignition key 32 restricts the movement of the slide piece 34 inward in the radial direction of the key rotor 28 and the lock plate 36. When the front end of the slider 58 abuts the slide piece 34, the downward rotation of the rear end of the lock plate 36 is restricted, and the engagement protrusion 64 of the slider 58 is engaged with the rear end of the lock plate 36. Is maintained.

  As a result, the state in which the rearward movement of the slider 58 and the lock bar 70 by the urging force of the compression spring 74 is retained is maintained, and the lock bar 70 releases the protrusion of the lock body main body 14 from the fixed piece 18. The maintained state is maintained. For this reason, permission to rotate the steering shaft and the steering wheel is maintained.

  On the other hand, when the key rotor 28 and the camshaft 42 are disposed at the “LOCK” position and the ignition key 32 is removed from the insertion hole 30 of the key rotor 28, the slide piece 34 is allowed to move inward in the radial direction of the key rotor 28. Thus, the slide piece 34 is moved radially inward of the key rotor 28 and the front end of the lock plate 36 is rotated upward by the urging force. Accordingly, the rear end of the lock plate 36 is rotated downward, and the engagement of the engagement protrusion 64 of the slider 58 with the rear end of the lock plate 36 is released, whereby the slider 58 and the lock bar 70 are moved. The lock bar 70 is moved rearward by the urging force of the compression spring 74, and the lock bar 70 protrudes rearward from the fixed piece 18 of the lock body main body 14. For this reason, the lock bar 70 is engaged with the steering shaft, and the rotation of the steering shaft and the steering wheel is locked.

  In the interlock unit 80, when the shift lever of the shift lever device 86 is operated to a shift position other than the “P” shift position, the solenoid 82 is driven, and the amount of protrusion of the plunger 82A from the solenoid 82 is set. Increase is regulated. For this reason, the rotation of the first link 90 integral with the rotation of the second link 92 is restricted, and the upward movement of the lower end of the first link 90 is restricted.

  Thus, when the key rotor 28 and the camshaft 42 are rotated from the “ACC” position to the “LOCK” position, the lower end of the second link 92 is torsioned by the restriction surface 54 of the camshaft 42 (outer cylinder 44). While being moved upward against the biasing force of the spring 94, the lower end of the first link 90 is restricted from moving upward and is engaged with the restriction surface 54 of the camshaft 42 (outer cylinder 44). . Therefore, the rotation of the key rotor 28 and the camshaft 42 from the “ACC” position to the “LOCK” position is restricted by the first link 90, and the extraction of the ignition key 32 from the insertion hole 30 of the key rotor 28 is restricted (locked). Is done.

  On the other hand, when the shift lever is operated to the “P” shift position, the solenoid 82 is not driven and the protrusion amount of the plunger 82A from the solenoid 82 is allowed to increase. For this reason, the rotation of the first link 90 that is integral with the rotation of the second link 92 is allowed, and the upward movement of the lower end of the first link 90 is allowed.

  Thus, when the key rotor 28 and the camshaft 42 are rotated from the “ACC” position to the “LOCK” position, the lower end of the second link 92 is moved upward by the restriction surface 54 of the camshaft 42 (outer cylinder 44). And the lower end of the first link 90 is moved upward so that the lower end of the first link 90 is separated from the outer peripheral surface of the camshaft 42 (outer cylinder 44). 42 (outer cylinder 44) is not engaged with the regulating surface 54. Therefore, the rotation of the key rotor 28 and the camshaft 42 from the “ACC” position to the “LOCK” position is permitted, and the ignition key 32 can be extracted from the insertion hole 30 of the key rotor 28.

  Further, in the key warning switch 96, when the ignition key 32 is inserted into the insertion hole 30 of the key rotor 28, the front end of the lock plate 36 contacts the slide piece 34 or the peripheral surface of the key rotor 28, and the lock plate 36. By restricting the upward rotation of the front side portion, the switch 96A of the key warning switch 96 is pressed downward by the front side portion of the lock plate 36. Thus, when the detection device 100 detects that the door has been opened in this state, the warning device 98 issues a warning.

  On the other hand, when the ignition key 32 is not inserted into the insertion hole 30 of the key rotor 28, the slide piece 34 is moved inward in the radial direction of the key rotor 28, and the front side portion of the lock plate 36 is rotated upward by the urging force. Thus, the downward pressing of the switch 96A by the front side portion of the lock plate 36 is released. Thus, when the detection device 100 detects that the door has been opened in this state, the warning device 98 does not issue a warning.

  Therefore, the camshaft 42, the cam gear spring 48, the return spring 50, the slider 58, the lock bar 70, and the compression spring 74 can be assembled into the lock body main body 14 from the same direction (rear side) at a time. Further, it is not necessary to assemble the cam shaft 42, the cam gear spring 48, the return spring 50, and the slider 58 from the front side of the housing cylinder 22 to the rear portion of the housing body 22 of the lock body main body 14 through the housing cylinder 22. Moreover, it is not necessary to assemble the slider 58 to the lock bar 70 by engaging the assembly protrusion 66 of the slider 58 with the assembly recess 72 of the lock bar 70 in the housing cylinder 22.

  This facilitates the assembly work of the camshaft 42, the cam gear spring 48, the return spring 50, the slider 58, the lock bar 70, and the compression spring 74 into the lock body main body 14, and the number of assembling steps for the lock body main body 14. Can be reduced. In addition, the assembly work of the lock unit 38 to the lock body main body 14 can be automated. Therefore, the assembling property of the steering lock device 10 can be improved.

  Further, the assembly operation of the lock unit 38 (the assembly operation of the cam shaft 42, the cam gear spring 48, the return spring 50, the slider 58, the lock bar 70, and the compression spring 74 with respect to the lock holder 16) can be facilitated. Assembly work can be automated. Therefore, the assembling property of the steering lock device 10 can be further improved.

  Further, the assembly box 78 of the interlock unit 80 is assembled to the lock body main body 14 from above, so that the solenoid 82, the support shaft 88, the first link 90, the second link 92, and the torsion assembled to the assembly box 78. A spring 94 is assembled to the lock body main body 14.

  Therefore, the solenoid 82, the support shaft 88, the first link 90, the second link 92, and the torsion spring 94 can be assembled to the lock body main body 14 at the same time from the same direction (upper side).

  As a result, the assembly work of the solenoid 82, the support shaft 88, the first link 90, the second link 92 and the torsion spring 94 to the lock body main body 14 can be facilitated, and the number of assembling steps for the lock body main body 14 can be further reduced. Can be made. Moreover, the assembly work of the interlock unit 80 to the lock body main body 14 can be automated. Therefore, the assembling property of the steering lock device 10 can be further improved.

  Furthermore, the assembly operation of the interlock unit 80 (the assembly operation of the assembly box 78, the solenoid 82, the support shaft 88, the first link 90, the second link 92, and the torsion spring 94) can be facilitated. Can be automated. Therefore, the assembling property of the steering lock device 10 can be further improved.
