PROBLEM TO BE SOLVED: To provide a kerosene vaporizer which does not cause pulsating combustion, clogging with tar, or oil leakage. SOLUTION: A cap 3 is made of a stainless steel having a relatively small heat conductivity and besides a relatively small thermal expansion coefficient so that the quantity of heat reaching an oil conveyor pipe 6 via the cap 3 from the carburetor body 1 may be limited effectively, whereby the abnormal temperature rise of the oil convey-or pipe 6 is prevented, and the occurrence of pulsating combustion is prevented, and also the occurrence of tar in the oil feed pipe 6 is suppressed. Moreover, the outside peripheral wall face of the cap 3 is so inserted as to be in contact with the inside peripheral wall of a vaporizing chamber 2, whereby the vaporizing chamber 2 is closed so that a clearance is hardly formed at welding.
