With this configuration, when the ignition heater is retreated from the ignition window hole after ignition and the shutter is closed, there is a risk that the bracket will fall off from the frame that is combined with the opening/closing shaft that transmits the movement of the bracket to the shutter. To prevent this, a method was used in which the stop shaft, which was fixed to the bracket and extended from the bracket, was stopped by an individual surface plate that was part of the frame.

The ignition window hole 3 corresponding to the tip of the wick 2 in the fire pan 1 is opened at the time of ignition, and the opening/closing shaft 7 is used to guide the normally closed shutter 4 through the lead groove 6 in the bracket 5. As it is opened, it moves to the rear of the lead groove 6.
Thereafter, due to the action of a spring 10 between the bracket 5 and an individual surface plate 9 that is a part of the frame 8, the bracket 5 slides on the frame 8 and moves to the rear of the shutter 4, and is combined with the frame 8 accordingly. The opening/closing shaft 7 moves to the front of the lead groove 6, and the shutter 4 is closed along with the lead groove 6. At this time, in order to prevent the bracket 5 from falling off the frame 8 and the opening/closing shaft 7 from coming off the bracket 5, a stop shaft 11 that is fixed to the bracket 5 and extended forward is attached individually, as shown in FIG. Surface plate 9
It is shaped so that it can be stopped at. This resulted in a complex structure, leading to high costs.

With a shutter that sometimes opens,
In order for the shutter to perform the above-mentioned operation, the shutter has an opening/closing shaft that transmits the movement of the bracket to the shutter, and in order to guide the opening/closing shaft, the end of the lead groove provided in the bracket is formed into a hook shape. The opening/closing shaft is placed against the opening/closing shaft to stop the shutter at an appropriate position, and the bracket is also prevented from falling off the frame combined with the opening/closing shaft.

ている。 After the wick 2 is ignited, the bracket 5 slides on the frame 8 and moves to the rear of the shutter 4.
In conjunction with this, the shutter 4 closes the ignition window hole 3. Here, due to the force of the spring 12, the opening/closing shaft 7 and the bracket 5, which are combined with the frame 8, tend to separate. By making the end 13 of the lead groove 6 into a hook shape, the opening/closing shaft is stopped at this end 13 and the bracket 5 is prevented from falling off from the frame 7. The structure is much simpler than the conventional one, making it possible to prevent it from falling off, and it has great practical effects in terms of cost and manufacturing.
