<P>PROBLEM TO BE SOLVED: To provide a heating device capable of uniformly reflecting infrared ray emitted from infrared ray radiant tubes to a heated face zone without twisting, bending or bowing reflection plates. <P>SOLUTION: This heating device 10 includes the first and second radiant tubes 12A, 12B connected with a burner combustion device 11, and a reflecting structure unit 14 for reflecting the infrared ray. The unit 14 is composed of first to third supports, an arch member curved with a prescribed radius of curvature, and the reflection plates 30A-30E curved with a prescribed radius of curvature along the curved shape of the arch member. In the unit 14, the reflection plates 30A-30E are connected in the longitudinal direction, an end section of one of the reflection plates 30 and an end section of the other reflection plate 30 are overlapped by a prescribed length at a position of the arch member, and the end sections are pressure-bonded to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
