(E) Operation With this configuration, when the damper blocks the bypass, the transmission arm extends and the spring expands, and the return force due to the extension of the spring causes the damper to move to one side of the bypass path on the inlet side. When the damper opens the bypass, the transmission arm is shortened and the spring is compressed, and the return force due to the compression of the spring causes the damper to press against the other contact surface. . Therefore, when opening and closing the bypass by the damper, the dimension (B) between the contact surfaces with which the damper contacts respectively.
Or the dimensional error between the rotation center of the damper drive motor and the pivot of the damper can be absorbed by the expansion and contraction action of both the transmission arm and the spring, and even if the dimensional error occurs due to variations during assembly. In addition to the fact that the bypass can be reliably closed by the damper, the damper can be pressed against another contact surface when the bypass is opened.

Further, since the coil spring is wound around the outer periphery of the overlapped portion of the first arm and the second arm, the first spring is compressed when it is compressed.
The arm and the second arm are stably held without being bent by the overlapping portion, and the return force is reduced to the second force.
Transmission to the damper via the arm is ensured.

The dimensional error between the contact surfaces with which the damper comes into contact when opening and closing the bypass path, or the dimensional error between the rotation center of the damper drive motor and the pivot of the damper, is determined by the expansion and contraction of both the transmission arm and the spring. Even if dimensional errors occur due to variations during assembly, the damper can reliably block the bypass path, and not only can the temperature of the hot water generated by the hot water heat exchanger be controlled well, but also the bypass When the road is opened, the damper can be brought into pressure contact with the contact surface, so that it is possible to suppress generation of chattering noise of the damper when the bypass is opened.

Since the coil spring is wound on the outer periphery of the overlapped portion of the first arm and the second arm, it is stably held by the overlapped portion of the first arm and the second arm during compression, and its return force is reduced. Transmission to the damper via the transmission arm is ensured.

An exhaust passage of a burner is provided with a bypass having a heat exchanger for hot water, and the inflow of combustion exhaust gas into the bypass is controlled by a rotatably supported damper, and a motor for driving the damper is provided. In the heating device configured to transmit the rotational force of the above to the damper via a transmission arm, the transmission arm is configured to be expandable and contractable by a first arm and a second arm whose ends are overlapped with each other. A coil spring for both compression and tension, one end of which is attached to the first arm and the other end of which is engaged with the second arm, is wound around the outer periphery of the overlapped portion of the first arm and the second arm. A heating device, characterized in that:
