It is known to do.

(C) Problems to be Solved by the Invention In the conventional structure described above, in addition to the lead up / down lever for adjusting the lead height position, an operating lever for operating an ignition device for igniting the wick raised to the combustion position is provided. Due to the provisions, the structure was very complicated. Therefore, in order to simplify the configuration, the core height adjustment operation and the ignition operation may be performed by a series of operations with a single operation lever. In that case, the operation range of the operation lever is Since it extends over the adjustment operation range and the ignition operation range, when the thermal power indicator is linked to this operating lever, the amount of movement of the thermal power indicator increases, and the amount of movement of the support that guides the vertical movement of the thermal power indicator is correspondingly increased. Since the height dimension must be set high, there is a drawback that the entire thermal power display device becomes large.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a compact thermal power display device capable of increasing the thermal power display range.

Further, the present invention is an oil combustor equipped with an operating lever for performing a core height adjusting operation and an ignition operation by a series of operations, and a thermal power indicator linked to the operating lever, when an ignition operation is performed by operating the operating lever. The amount of movement of the thermal power indicator is set to be much smaller than the amount of movement of the thermal power indicator at the time of core height adjustment operation by operating the operation lever.

(E) Operation In the thermal power display device of the oil combustor according to claim (1),
The moving amount of the thermal power indicator relative to the moving amount of the operating lever is configured to be greatly reduced in the ignition operating range compared to the core height adjusting operating range, so that the operating range spans the core height adjusting operating range and the ignition operating range. Even when the operation lever and the thermal power indicator are interlocked, the amount of movement of the thermal power indicator in the ignition operation range is extremely small, so there is no need to make the thermal power indicator sufficiently larger than the display window in advance, The support of the thermal power display and the storage space for these can be made as small as possible,
It can be used as a compact firepower display device. In addition, since the movement amount of the thermal power indicator can be increased in the core height adjusting operation range, the thermal power display range can be increased and the display can be easily viewed.
