Claims

[Claim for Utility Model Registration] In a tube heater that emits radiant heat from the outer wall surface of a tube, heater elements disposed in the tube in the axial direction are kept in a predetermined positional relationship with each other and with the tube. A supporting insulator for a tube heater that supports the heater element at a plurality of positions in the axial direction, the support insulator having a first through hole parallel to the axial direction in the center and a plurality of holes in the outer periphery through which the heater element is inserted. a plate-shaped first insulator having a second through hole and protrusions on the periphery of both side openings of the first through hole; The second insulator is formed in a shape corresponding to the protrusion of the insulator and engages with the protrusion of the adjacent first insulator at the opening to connect the adjacent first insulator. Characteristic support insulator for tube motors.
