PURPOSE: A structure for measuring the pressure of a hot blast device is provided to enable a user to directly check the pressure of the hot blast device by installing a pressure measurement indicator for measuring the pressure generated by a vane pump at the outside of a hot blast device body. CONSTITUTION: In a hot blast device, an air line(26) connects a vane pump(28) to a nozzle assembly(22), and is divided into a first air line(26a) and a second air line(26b) by a T-shaped nozzle(45). The second air line is connected to the nozzle assembly. The first air line is connected to a pressure measurement indicator(40) for measuring the pressure generated by the vane pump. The pressure measurement indicator is installed at the outside of a hot blast device body(10) so that a user directly checks the pressure indicated on the pressure measurement indicator.
