The ignition angle 28 whose base end is supported by the pivot 29 rotates toward the lamp wick 3 using the pivot 29 as a fulcrum, and brings the ignition heater 32 into contact with the lamp wick 3 . During this operation, the heater angle 28 comes into contact with the upper end of the switch piece 12, and the ignition heater 32 is energized by the power source 46 to ignite the lamp wick 3.
After the ignition is completed, when the pressing force on the push-down button 41 is released, the lifting body 19, the heater angle 28, and the ignition lever 37 return to their original positions at the same time due to the weight of the combustion tube 4 and the spring 43.

(f) Effect of the invention As described above, according to the ignition device of the invention, the depressing force of the push-down button acts on the ignition lever, converting a small force into a large force and moving the lifting body upward. At the same time, this lifting body is made to move linearly in the vertical direction by the guide part of the support base, so a large lifting force acts on the lifting body, and even a large combustion cylinder can be lifted smoothly. The ignition operation can be performed reliably with a small amount of force, making it possible to provide a device that is ideal for large combustors.

Further, unlike the conventional method, a combustion cylinder lifting body is not attached to the ignition angle, and since no large force is applied to the ignition angle, the ignition angle can be rotated smoothly and stable ignition can be performed. Further, since the support base is provided with a guide portion that guides the lifting body in the vertical direction, it is possible to construct a strong base that is reinforced by the guide portion.
