Further, in the heating element chamber 4 of the casing 1, a reflecting plate 7 having a curved parabolic cross section for reflecting radiation from the electric heating element is disposed with its curved concave surface facing forward. Both left and right ends of the reflecting plate 7 are connected to the open front edge of the casing body 1a via coupling members 8, 8, which also serve as decorative frames, attached to the open front edge.

That is, as shown in FIGS. 5 and 6,
The coupling members 8, 8 are attached to the opposing front open end edges of the main body 1a of the casing 1 in a fitted state over the entire length of the casing 1 at the outer surface of the rear end of the front end thereof. A vertical locking groove 8c, which is open toward the inside of the casing main body 1a, is formed inside the front back portion.

On the other hand, in the heating element chamber 4 inside the casing 1, there is a reflector holding plate 12 which is curved and deformed to have a parabolic cross section by a pair of half-split members 12a, 12a. open end side)
For example, four of them are arranged in a row with a predetermined interval above and below so as to face the same direction. Each reflective plate holding plate 1
The front end portions of the two halves 12a and 1 are respectively connected to the rear end portions of the respective connecting members 8 by screws 13, while the curved top portions of the respective reflective plate holding plates 12 are connected to the two halves 12a, 1
The connecting portions 2a are integrally connected to each other by screws 14. Therefore, the reflective plate 7 is curved to have a parabolic cross section, and its back surface is brought into contact with the curved concave surface 12b of each of the reflective plate holding plates 12, and both end portions are connected to each of the connecting members 8, respectively. It is fixedly supported by the casing 1 by being fitted into and engaged with the locking groove 8c.

Each of the coupling members 8 is extended in the longitudinal direction (vertical direction) from the coupling portion of the reflection plate 7 (a portion corresponding to the heating element chamber 4) to the same length as the entire length of the casing body 1a, so that an extension portion 8a is formed. As shown in enlarged detail in FIG. 3, fitting grooves 9 extending in the longitudinal direction (vertical direction) are formed in the facing surfaces 8b of the respective extension portions 8a. As shown in FIG. 4, front plates 1d and 1e welded at right angles to the front edges of the respective lids 1b and 1c are fitted between the fitting grooves 9 and 9, and each of the lids 1
