[Unlocking operation by the steering lock device 1]
Next, the unlocking operation by the steering lock device 1 will be described with reference to FIGS. Here, FIG. 6 is a partial side view showing the locked state in the steering lock device 1 according to the embodiment of the present invention from the lock unit 6 side. FIG. 7 is a partial plan view showing the unlocked state from the return spring 10 side in the steering lock device 1 according to the embodiment of the present invention.

(Locked state)
As shown in FIG. 4, when the steering shaft 14 is locked by the steering lock device 1, the lock member 4 moves toward the steering shaft 14 and maintains the engaged state. In this locked state, the slide member 31 of the unlock maintaining unit 7 incorporated in the lock body 2 moves in the biasing direction ED by the biasing force of the elastic member 32, and the slope of the second cam portion 34 of the camshaft 35. It is pressed against the surface 34a. Thus, even if the lock member 4 is not intended to move in the steering / unlock direction UD (upward in FIG. 4), the second cam portion 34 is attached to the elastic member 32 if the camshaft 25 is not rotated. Since the slide member 31 is not moved to the opposite side of the urging direction ED against the force, the lock member 4 is moved again in the steering lock direction LD (downward in FIG. 4) by the elastic force of the return spring 10. And maintain the locked state.

(At the time of transition from locked state to unlocked state)
When the operator operates the knob portion 36 to rotate the rotor 30 of the knob unit 3 clockwise, the camshaft 35 driven by the knob unit 3 also rotates in the same direction.

  At this time, as shown in the order of FIGS. 3 and 6, the first cam portion 33 moves the lock member 4 in the steering / unlock direction via the first cam contact portion 21 while resisting the elastic force of the return spring 10. Move to UD (above FIGS. 3 and 6).

  Further, as shown in the order of FIGS. 2 and 5, the second cam portion 34 opposes the slide member 31 via the second cam contact portion 43 in the opposite direction of the urging direction ED while resisting the elastic force of the elastic member 32. Move to the side (left side in FIGS. 2 and 5). Then, as shown in FIGS. 5 to 7, the slide member 31 engages with the engaging portion 22 of the lock member 4 as the lock member 4 and the slide member 31 move in the predetermined direction.

  Here, as long as the knob portion 36 of the knob unit 3 does not rotate counterclockwise, the second cam portion 34 continues to push the slide member 31 to the side opposite to the urging direction ED, so that the lock member 4 remains unlocked. Keep doing.

[Locking operation by the steering lock device 1]
When the operator operates the knob portion 36 and the rotor 30 of the knob unit 3 rotates counterclockwise, the camshaft 35 that follows the knob unit 3 also rotates in the same direction.

  At this time, as shown in the order of FIGS. 5 and 2, the second cam portion 34 uses the elastic force of the elastic member 32 to push the slide member 31 through the second cam contact portion 43 in the urging direction ED ( Move to the right of FIGS. Thereby, as shown in FIGS. 2 to 4, the engaged state of the slide member 31 and the lock member 4 is released.

  Further, as shown in the order of FIGS. 6 and 3, the first cam portion 33 uses the elastic force of the return spring 10 to move the lock member 4 via the first cam contact portion 21 in the steering lock direction LD ( 3 and FIG. 6).

  Here, as long as the knob portion 36 of the knob unit 3 does not rotate clockwise, the second cam portion 34 does not push the slide member 31 to the opposite side of the biasing direction ED, and the elastic member 32 attaches the slide member 31. In order to keep pushing in the urging direction ED, the lock member 4 keeps the locked state.

[Effect of the embodiment]
(1) In the steering lock device 1 according to the embodiment of the present invention, when the knob unit 3 rotates in the steering / unlock direction UD, the second cam portion 34 of the cam shaft 35 slides on the unlock maintaining unit 7. So as to engage the engaging portion 22 of the locking member 4 moved in the steering / unlocking direction UD by the first cam portion 33. Configured. Accordingly, there is an effect that the unlocked state can be maintained without performing a key insertion operation such as a conventional mechanical key. That is, a function corresponding to a conventional locking lever can be added to the knob type steering lock device. In addition, since the unlock pin is less likely to be damaged or deformed even when the knob is repeatedly operated, the unlock state is reliably maintained during traveling of the vehicle equipped with the steering lock device 1 according to the embodiment of the present invention. It has the effect of being able to.

  (2) The knob unit 3 and the cam shaft 35 are arranged coaxially, and the slide member 31 is arranged parallel to the axial direction of the cam shaft 35. The second cam portion 34 is a slope formed on the side surface 37 a of the cam shaft 35. That is, the second cam portion 34 is formed on the unused side surface 37a of the camshaft 35, and the unlock maintaining unit 7 having a simple structure is arranged in parallel to the camshaft 35. Therefore, the conventional knob type steering lock device is provided. Thus, there is an effect that a large certainty and reliability can be obtained for maintaining the unlocked state without making a large change.

  (3) The second cam portion 34 is provided substantially in the middle of the cam shaft 35 in the axial direction. A substantially intermediate portion in the axial direction of the camshaft 35 has a strength greater than that of both ends of the camshaft 35 subjected to various processing such as cam processing. Therefore, even when the first cam portion 33 of the camshaft 35 or the first cam contact portion 21 of the lock member 4 is deformed or damaged due to traveling vibration or impact, the slide member 31 and the engaging portion 22 of the lock member 4 are used. It has the effect that an unlocked state can be maintained by engagement by.

  (4) The third cylinder part 11 arranged in parallel with the axial direction of the first cylinder part 8 is formed inside the lock body 2, and the unlock maintaining unit 7 is coaxially arranged inside the third cylinder part 11. Since no other parts are arranged on the side of the knob type steering lock device 1 and there is a relatively large space, the unlock maintaining unit 7 is arranged without sacrificing other components of the steering lock device 1. It has the effect that it can be done.

  (5) The third cylindrical portion 11 provided inside the lock body 2 is configured by the large cylindrical portion 12 and the small cylindrical portion 13 that are coaxially disposed adjacent to each other. Further, the slide member 31 is constituted by a slide pin portion 41 having a predetermined size and shape, a piston portion 42 and a second cam contact portion 43, and a coil spring as the elastic member 32 is arranged on the same axis. Thereby, since the arrangement | positioning space of the 3rd cylinder part 11, the slide member 31, and the elastic member 32 can be elongated, space can be used effectively and the lock body 2 of the part which arrange | positions the 3rd cylinder part 11 can be used. If the thickness of the lock body 2 is equal to or greater than the third cylindrical portion 11, the lock body 2 can be made without substantially changing the outer shape or inner shape of the lock body 2. Thereby, when using a type | mold for shaping | molding of the lock body 2, it can respond | correspond by the change without changing the type | mold.

  As mentioned above, although the steering lock device of the present invention was explained based on the above-mentioned embodiment, the present invention is not limited to the above-mentioned embodiment, and can be implemented in various modes without departing from the gist thereof. It is possible.
