PURPOSE: To improve mounting operability of a grip and to control a rotating range of the grip by a simple structure by mounting the grip without necessity of a screw clamp.
CONSTITUTION: A heater has a substantially U-shaped grip 12 formed of a metal plate and rotatably mounted at a heater body, and comprises pivoted pieces 15 bent inward at both ends of the grip 12, a plurality of detents 16 bent upward or downward and louvered at ends of the pieces 15, and a pair of mounting openings 18 in which the pieces 15 are inserted at the body. The opening 18 has a controlling function for controlling a rotating range of the grip 12 and a shape for telescoping the detents 16 only at an intermediate position of a rotating range controlled by the function.
