Patent ID: 8840398

Claim:
A gas lighter with a roller-rotation restraining part, comprising: a tank for storing a gas; a nozzle for emitting the gas stored in the tank; a lever for opening and closing the nozzle; a lighter flint disposed adjacent to the nozzle; a roller comprising a spark wheel and a pair of side wheels, the spark wheel being engageable with the lighter flint to cause the gas emitted from the nozzle to be ignited, a side wheel being disposed on each sides of the spark wheel, respectively, the side wheels having a plurality of operating saw teeth formed around an outer peripheral surfaces thereof; and a cap surrounding the nozzle, the cap being formed with an upper surface defining a flame discharge hole through which an ignited flame is discharged, wherein protrusions on the upper surface of the cap extend from the flame discharge hole to define a roller-rotation restraining part, the roller-rotation restraining part comprising an extension of the upper surface of the cap and being disposed at an angle toward and contacting a corrugated surface of the roller, so that a distal end of the roller-rotation restraining part extension is caught by and disposed in substantially continuous contact against the roller, thereby imposing a substantially continuous rotation-restraining force on the roller during the rotation of the roller for ignition of the gas emitted from the nozzle.
