The present invention relates to a cigarette lighter for a vehicle that can increase safety by exposing the resistor to the outside only when the cigarette lighter is used, and includes an electrode part for supplying power, and a plurality of guide grooves 110 are formed on an inner circumferential surface of the vehicle body. A socket 100 fixed to the socket; Is inserted into the socket 100 is made of a plug 200 which generates heat by contact with the electrode portion, the plug 200 is a cylindrical outer body portion 210 and; A resistor 220 that is received into one side of the outer body portion 210; A handle 230 connected to the resistor and capable of linear movement; A first elastic body 240 inserted into the outer body portion 210 to elastically support the handle; A ring-shaped driving ring 250 rotatably provided at a front end of the outer body portion in which the resistor is located, and having a plurality of protrusions inserted into the guide recess 110; A cover part 260 fastened to a front end of the outer body part to open and close an opening of the outer body part 210 in association with rotation of the driving ring; It is composed of a second elastic body 270 elastically supported between the handle and the drive ring, it is an invention that has the effect of increasing the safety by preventing burns or fire by preventing the resistor in the heating state is not exposed to the outside.;Cigarette lighters, plugs, resistors, covers, blades, drive rings, protrusions.
