Next, the operation of the present invention configured as described above will be described. The combustion process of the oil warm air heater is similar to that of the conventional example shown in FIG. Now, for example, when an external force is applied to the pump (3) of the warm air heater, a similar force is also applied to the yoke (4). At this time, the pump (3) includes the O-rings (30a) and (30b) and the buffer cylinder (3
It is attached to the constant oil level gauge (5) via 2), and in particular, since the buffer cylinder (32) is compressed in the circumferential direction or has a small gap, it may rotate greatly even if external force is applied. Therefore, the stepped screw (22) and the yoke (4) do not come into direct contact with each other. For this reason, it does not transmit vibrations of 1 KHz or more, which are particularly noticeable to humans.

EFFECTS OF THE INVENTION As is apparent from the above description, according to the present invention, the yoke is held in non-contact with the tank side pipe and the carburetor side pipe by each vibration-proof sealing material, and is fastened by the buffer means. Since the means is held in a non-contact state, it is possible to prevent the vibration generated by the pump from being transmitted from the yoke to the pipe on the tank side or the pipe on the carburetor side via the fastening means. For this reason, it is possible to reduce the high-frequency sound that is audible to human beings inexpensively and reliably.
