The setting of the timing unit 206, and the like. Furthermore, the present invention is not limited to the above embodiment, and can be implemented by appropriately deforming. For example, in the above, the heating conditioner is exemplified by a gas furnace, and the present invention is also applicable to other heating conditioners such as electromagnetic heating conditioners. In this case, the heating means for conditioning is to use an electromagnetic heating means instead of a gas burner. Moreover, in the above, the operation unit for performing at least a part of the operation of the heating means is described in the case where the timing unit for automatic fire extinguishing is mounted on the top plate, but other operation units such as a grill conditioning timer or conditioning are provided. The type of temperature adjustment device installed on the top plate can also be applied. Further, in the above, the connecting member for fixing the timing unit 6 or 206 to the top plate 1 or 101 uses the screwing member 7 or 307 screwed to the cylindrical portion 64 or 264, but may alternatively be used in other manners. Other connecting members that are connected to the outer circumference of the cylindrical portion 64 or 264. However, such a connecting member also has a crotch portion or an upper extending portion as in the case of the screw member 7, and it is necessary to cause the crotch portion to adhere to the surface of the top plate. For example, it is conceivable to have a mechanism that is fitted to the outer circumference of the cylindrical portion 64 and that continues to impart a force for adhering the crotch portion to the top plate after the fitting. It is conceivable that the mechanism for continuing the biasing force generates a force acting on the cam surface provided on one of the cylindrical portion 64 or the connecting member and elastically acting on the cam surface to press the connecting member toward the top plate. Further, in the above, the example of the connecting member is a screwing member of various states shown in Figs. 2, 4, and 20 201229440 ίο, but it is also possible to adopt a state in which 2 or more of the states are within the possible range. A connecting member formed by combining them. For example, the gasket material 73 or 7 of Fig. 5 and the annular projections 773, 774, and 775 of Fig. 9 can also be applied to Fig. 2, Fig. 4, Fig. 6, Fig. 8, Fig. 1 Any screwing member. Further, the lower extending portions 875 and 876 of Fig. 8 and Fig. 1 can also be applied to the state of Fig. 2, Fig. 4, Fig. 6, and Fig. 9. However, when it is applied to the state of Fig. 4, the gasket member 9 is preferably a resin material having a sealing property, for example, a tamper, and the screwing member may be screwed to the cylindrical portion, and the lower extending portion may be spaced apart from each other. The gasket is easily attached to the inner wall of the through hole U for the entire circumference. Further, the state of the screw members may be applied to other connecting members that are connected in other manners as described above.
