ータ。[Scope of Claim for Utility Model Registration] (1) In a gas-type bolt heater in which combustion gas generated by the flame generated at the tip of the burner is discharged through a heat-generating tube through a hole for the bolt heater or between the hole for the bolt heater and the heat-generating tube. The inner surface of the frame guide, which comes in contact with the flame, from the inlet to the heat generating tube connection area has a smooth tapered constriction structure, and the surface of the constriction structure is coated with ceramic, and the bolt heater hole is non-penetrating. A gas-type bolt heater characterized in that a gap adjustment member is provided between the bottom and the tip of the heating tube to regulate the gap between the two. (2) Claim 1 of the utility model registration claim, characterized in that a plug provided with a vertical through hole and a horizontal hole communicating with the vertical through hole as an interval adjustment member is inserted into the bottom of a non-through hole for a bolt heater. Gas-powered bolt heater as described. (3) The gas-type bolt heater according to claim 1, which is a utility model registration, wherein the distance is adjusted by connecting a heating tube of an appropriate length as a distance adjusting member.
