## Abstract

An electrical steering column lock includes a locking guide that advances and retreats with respect to a lock ring by a driving part, and a lock bar that advances and retreats toward and from the locking guide within a predetermined distance in the same direction as that of the locking guide. The lock bar has a leading end disposed toward the lock ring, and is elastically biased toward the locking guide in a lock ring direction. One side of the locking guide is provided with a protrusion. A slider that advances toward the locking guide or retreats from the locking guide is positioned facing the protrusion, and the slider is provided with a grooved part into which the protrusion is inserted.

## Claims

### Claim 1

An electrical steering column lock, comprising:
a locking guide driven by a driving part that advances and retreats with respect to a lock ring;
a lock bar that advances and retreats toward and from the locking guide within a predetermined distance in the same direction as the advance and retreat direction of the locking guide, the lock bar having a leading end disposed toward the lock ring, and being elastically supported by the locking guide biased in a direction toward the lock ring,
wherein one side of the locking guide is provided with a protrusion,
a slider that advances toward and retreats from the locking guide, positioned facing the protrusion of the locking guide, and wherein
the slider is provided with a grooved part into which the protrusion is insertable.

### Claim 2 (depends on 1)

The electrical steering column lock according to claim 1, wherein the slider is elastically biased toward the locking guide,
at least any one surface of the slider at which the protrusion of the locking guide contacts the grooved part is provided with an inclined surface, the inclined surface advancing the locking guide, such that the slider advances toward the locking guide while the grooved part receives the protrusion of the locking guide along the inclined surface, and the inclined surface retreating from the locking guide, such that the slider retreats from the locking guide while the grooved part receiving the protrusion is separated from the protrusion along the inclined surface.

### Claim 3 (depends on 1)

The electrical steering column lock according to claim 1, wherein the lock bar is provided with a key home, and
the slider includes a key member that is inserted into the key home while the slider advances, and is separated from the key home while the slider retreats.

### Claim 4 (depends on 3)

The electrical steering column lock according to claim 3, wherein the key groove is configured such that the key member may be inserted into and separated from the key groove in a state in which the lock bar advances so as to be locked into the lock ring.

### Claim 5 (depends on 1)

The electrical steering column lock according to claim 1, wherein the locking guide is provided with a pin, and
the lock bar is provided with an elongated hole that is longitudinally provided in the same direction as the advance and retreat direction thereof and is elastically supported to the locking guide biased in a lock ring direction in the state in which the elongated hole receives the pin.
