PROBLEM TO BE SOLVED: To extend the service life of a chuck and the continuous operating time of the chuck and to improve the working efficiency by suppressing the flow of the flame of a burner to the chuck so as to suppress the rise of the temperature of the chuck. SOLUTION: In the device for processing a preform for an optical fiber, which is provided with the chuck for holding a dummy (an tip end of the preform) of the preform for the optical fiber and for rotating the preform at a constant speed, a burner for heating the the preform for the optical fiber with the flame, and a shielding member for preventing the chuck from being parched with the flame of the burner, the shielding member is constituted of a shielding plate having a first loading slot and a cover having a second loading slot which is smaller than the first loading slot, and the chuck is allowed to hold the dummy of the preform for the optical fiber, which is loaded into a dummy loading slot constituted of the first loading slot and the second loading slot.
