Abstract

본 발명은 자동차 키 실린더에 관한 것으로, 특히 키 실린더를 회동시킬 때 키 실린더의 외통과 내통이 같이 회전하는 것을 방지하기 위하여 실린더 케이스와 외통의 걸림돌부를 개선한 자동차 키 실린더에 관한 것이다. 종래에는 자동차키를 오래 사용하다 보면 키 자체가 마모되어 처음과 같이 잘 맞지 않는 경우가 있는데, 이러한 자동차 키를 가지고 억지로 몇번 사용하다 보면 고정되어 있어야 할 키 실린더의 내통이 같이 움직이는 문제가 발생되었다. 본 발명은 키 실린더의 외통(10) 상,하부에 양측으로 경사면(44)을 갖는 삼각걸림돌부(46)를 형성하고, 삼각걸림돌부(46)와 접하는 스냅링 고정홈(34) 일측에 경사부(48)를 형성하여 이루어지는 것으로, 삼각걸림돌부(46)가 스냅링걸림홈(34)에 위치하도록 하고, 탄성부(36)가 형성된 스냅링(38)을 걸착시키면, 삼각걸림돌부(46)의 경사면(44)에 압착되어지고 있는 스냅링(38)의 압착력이 경사면(44)과 경사부(48)로 전달되어 발생된 마찰력에 의해 키 실린더 외통(10)은 견고하게 고정되어 내통(12)이 회전하더라도 외통(10)은 고정되어지는 효과를 얻을 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile key cylinder, and more particularly, to an automobile key cylinder in which an outer cylinder and an inner cylinder of a key cylinder are prevented from rotating together when the key cylinder is rotated. Conventionally, when a car key is used for a long time, the key itself is worn out, so it may not fit well as the first time. When a user uses such a car key several times, the inner cylinder of the key cylinder, which should be fixed, moves together. The present invention forms a triangular engaging protrusion 46 having inclined surfaces 44 on both sides of the upper and lower outer cylinders 10 of the key cylinder, and an inclined portion on one side of the snap ring fixing groove 34 in contact with the triangular engaging protrusion 46. And forming the 48, and when the triangular engaging protrusion 46 is positioned in the snap ring engaging groove 34, and the snap ring 38 having the elastic portion 36 is fitted thereto, the inclined surface of the triangular engaging protrusion 46 is formed. The pressing force of the snap ring 38 being squeezed by the 44 is transmitted to the inclined surface 44 and the inclined portion 48 and the key cylinder outer cylinder 10 is firmly fixed by the friction force generated so that the inner cylinder 12 rotates. Even if the outer cylinder 10 can be obtained that the effect is fixed.
