In a kerosene heater in which combustion is effected by means of a wick (3), a wick raising and lowering mechanism (5) for raising and lowering the wick (3) and a fine-regulatable wick raising and lowering mechanism (20) for finely controlling the combustion rate of the wick (3) are provided. The fine-regulatable wick raising and lowering mechanism (20) generally includes a rack (23), a wick-raising pinion (32), a wick-lowering pinion (34), a first manually operable member (27) for driving the wick-raising pinion (32), and a second manually operable member (28) for driving the wick-lowering pinion (34). The combustion rate can be finely, easily, and safely regulated by means of an operation between the rack (23) and the wick-raising and lowering pinions (32, 34).
