The present invention relates to an anti-theft wheel nut device and a manufacturing method thereof. According to the present invention, a body and a key forming portion of the wheel nut are separately manufactured with separate components, and the key is formed with reference to a base track portion, thereby being able to reduce processing time and costs. The anti-theft wheel nut device comprises: the body having a screw hole formed in one side thereof to be coupled to a screw portion formed on a wheel of a vehicle and a head portion formed on the other side; and the key forming portion formed on the head portion and having a key-shaped groove portion to prevent the wheel from being stolen, wherein an accommodation groove portion is formed in the head portion of the body, and the key forming portion is inserted and press-fitted into the accommodation groove portion. The anti-theft wheel nut device further comprises a protective cover portion which is formed to surround a side surface of the head portion to protect the side surface of the head portion, and in which a through hole is formed to expose the key forming portion to the outside. The accommodating groove portion of the head portion communicates with the screw hole of the body. The key forming portion further comprises the other groove portion extended inward from a lower surface opposite to the accommodating groove portion and communicating with the screw hole when the key forming portion is press-fitted into the accommodation groove portion.

    본 발명은 휠너트의 몸체와 키 형성부를 별도의 부품으로 개별 제작하고, 베이스 트랙부를 기준으로 키를 형성하여 가공 시간과 비용을 절감할 수 있는 도난 방지용 휠 너트 장치 및 이의 제조 방법에 관한 것으로서, 차량의 바퀴 휠에 형성된 나사부와 체결될 수 있도록 일부분에 나사홀이 형성되고, 타부분에 머리부가 형성되는 몸체; 및 상기 머리부에 형성되고, 휠 도난을 방지할 수 있도록 키 형상의 홈부가 형성되는 키 형성부;를 포함하고, 상기 몸체의 상기 머리부에 수용홈부가 형성되고, 상기 키 형성부는 상기 수용홈부에 억지끼움으로 압입되고, 상기 키 형성부가 외부로 노출될 수 있도록 관통홀이 형성되고, 상기 머리부의 측면을 보호할 수 있도록 상기 머리부의 측면을 둘러싸는 형상으로 형성되는 보호 덮개부;를 더 포함하고, 상기 머리부의 수용홈부는 상기 몸체의 나사홀에 연통되고, 상기 키 형성부는 상기 홈부 반대 쪽 하면으로부터 내측으로 신장되고 상기 수용홈부에 압입 시 상기 나사홀에 연통된 다른 홈부를 더 포함할 수 있다.
