For example, the guide block 10 and the tilt locking assembly 50 may be installed on the side portion 23 of the tilt housing 20. [

The guide block 10 has a first tooth 13. As shown in FIGS. 2, 5 and 6, the first teeth 13 may be formed on one of the inner surfaces forming the guide slot 11 of the guide block 10.

The tilt locking assembly 50 includes a locking block 510, a locking cage 520, a cam block 530 and an elastic member 540.

The locking block 510 has second teeth 511 that are pre-mated with the first teeth 13 of the guide block 10. When the first teeth 13 and the second teeth 511 are engaged with each other, tilting is possible. When the teeth are released, tilting is possible. The locking block 510 is installed with the second teeth 511 facing the first teeth 13.

The locking cage 520 accommodates the locking block 510. The locking cage 520 has a receiving space 521 into which the locking block 510 is inserted and the locking block 510 is disposed in the receiving space 521. The locking cage 520 includes an opening portion 523 and the second teeth 511 of the locking block 510 are exposed through the opening portion 523 so that the first teeth of the guide block 10 13). Meanwhile, the locking cage 520 may have a through hole 526 through which the tilt rod 30 passes.

The cam block 530 is fastened to the tilt rod 30 to rotate together with the tilt rod 30. The cam block 530 has a through hole 531 formed along the longitudinal direction of the tilt rod 30 and the tilt rod 30 is inserted into the through hole 531. At this time, the tilt rod 30 and the through hole 531 are formed to rotate together, and may have, for example, a polygonal cross-sectional shape. At this time, when the telescopic lock / unlock function is provided, the cam block 530 is slidable in the axial direction of the tilt rod 30. At this time, the inner surface of the through hole 531 of the cam block 530 or the surface of the tilt rod 30 can be coated with grease so as to enable smooth slip.

The cam block 530 pushes and moves the locking block 510 so that the second teeth 511 are engaged with the first teeth 13 in correspondence with the rotation thereof. The cam block 530 can apply a force to the locking block 510 by the cam action. For example, the cam block 530 may have protrusions 533 for camming action. The position of the locking block 510 is changed according to the rotational position of the protrusion 533 so that the second teeth 511 can be selectively engaged with the first teeth 13. The locking block 510 may be provided with an inclined contact surface 513 for contacting the protrusion 533 of the cam block 530.

The cam block 530 may include a circular arc portion 535 provided on the opposite side of the protrusion 533. The locking cage 520 may include a circular arc portion 535 in a state of being in surface contact with the circular arc portion 535, (Not shown). For this, the depression 525 may be formed to have the same arc shape as the circular arc portion 535.

The elastic member 540 provides the locking block 510 with an elastic force acting in a direction in which disengagement of the first and second teeth 13 and 511 is released. That is, when the cam block 530 pushes the locking block 510 and thereby the engagement of the first and second teeth 13 and 511 is maintained, the elastic member 540 is tilted in the compressed state When the cam block 530 is rotated and the pushing force of the locking block 510 is removed, the locking block 510 is pushed in the direction away from the first teeth 13 by the elastic restoring force of the elastic member 540 Whereby the tilting can be performed by releasing the tilting locking.

The elastic member 540 may be interposed between the locking cage 520 and the locking block 510 to elastically support the locking block 510 with respect to the locking cage 520. For example, the elastic member 540 may be installed in contact with the seating surface 527 of the locking cage 520 and the seating surface 515 of the locking block 510, respectively.

The insert cam 610 is installed in the tilt lever 40 to rotate together with the tilt lever 40 and the cam member 620 is disposed to face the insert cam 610. [ 2 and 4, one or more protrusions 611 are formed on the insert cam 610, and one or more inclined surfaces 621 contacting the protrusions 611 are provided on the cam member 620. When the insert cam 610 rotates while the projection 611 is in contact with the inclined surface 621, the cam member 620 is pushed away from the insert cam 610. The guide block 10 is pushed by the insert cam 610 so that the side surface portion 23 of the tilt housing 20 is deformed and brought into close contact with the steering column 1. [ As a result, the upper jacket 2 of the steering column 1 is restricted from moving in its axial direction, and the telescopic function is locked.

On the other hand, the cam spring 630 elastically supports the cam member 620 with respect to the cover plate 550. When the tilt lever 40 is rotated in the opposite direction in the telescopic locking state, the projection of the insert cam 610 moves along the inclined surface of the cam member 620, and the cam member 620 Is pushed toward the insert cam 610. Accordingly, the side surface portion 23 of the tilt housing 20 is restored to the original state by the restoring force, so that the upper jacket 2 of the steering column 1 can move in the axial direction, and the telescopic operation can be performed.

At this time, the insert cam 610 and the cam member 620 may be provided with through holes 613 and 623 through which the tilt rod 30 passes, respectively. The cam spring 630 may be provided with a through hole 633 through which the tilt rod 30 passes.

3, the tilt rod 30 is installed to penetrate the cam member 620, the guide block 10, and the tilt locking assembly 50, and further the tilt rod 30 is provided on the steering column 1 (Not shown). A tilt lever 40 is installed at one end of the tilt rod 30 and a bolt (not shown) is attached to a thread 31 at the other end of the tilt rod 30 through the upper jacket 2, Can be coupled and fixed.

According to the embodiment of the present invention, the direction in which the tilt housing is deformed, i.e., the direction in which the side portion of the tilt housing 20 is deformed (i.e., the width direction of the steering column) And the teeth directions of the second teeth 510 of the locking block 510 are not related to each other, it is possible to prevent latching upon tilting.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
