Patent ID: 7174755

Claim:
A mounting structure of a steering column locking device, comprising: a connection housing mounted at a first end thereof to a steering column, with a coupling slot formed in a second end of said connection housing; a coupling protrusion provided on said steering column locking device so that said coupling protrusion is movably inserted into said coupling slot of said connection housing; and a locking pin fitted into said coupling slot to support said coupling protrusion such that said coupling protrusion remains in a stationary state, said locking pin breaking when a predetermined amount of impact or more is applied to said coupling protrusion, wherein the coupling slot comprises: (i) a guide slot into which the coupling protrusion is inserted; (ii) a locking slot extending in a direction perpendicular to the guide slot, so that said coupling protrusion is inserted into and locked into the locking slot; and (iii) two support notches extending at predetermined positions from opposite side edges of the guide slot in opposite directions; and wherein the locking pin comprises: (i) a pin body fitted into the guide slot of the coupling slot; (ii) two wing parts fitted into the respective support notches; and (iii) a support part to contact and support the coupling protrusion inserted into and locked to the coupling slot, the support part breaking when a predetermined amount of impact or more is applied to the coupling protrusion.
