Abstract
An automatic fire-extinguishing device for an oil burner capable of being manufactured with a low cost, compacted in construction and actuated with high accuracy. In the device, a gear which is loosely fitted on a wick actuating shaft and has a return spring loosely fitted on the shaft and fixed between the gear and a burner body is formed with a cutout about a portion thereof opposite to a stopper engaged with the gear when the gear is at a wick raising position. At the cutout is arranged a stop gear so as to be engaged with the stopper at the wick raising position, which is formed of a material having a friction coefficient smaller than that of the gear.
