Description of the Related Art Conventionally, this type of temperature adjusting device is generally one in which a base is set to an arbitrary temperature and adjusted by rotating a dial attached to an adjusting shaft of a thermostat. Further, it is considered that the operation body is replaced with a dial, and a rack gear is engaged with a pinion gear attached to an adjusting shaft of a thermostat so that a knob is slid to rotate the adjusting shaft. .

[0003]

However, while such a knob sliding type has excellent operability, in the case of a structure in which a rack gear is meshed with a pinion gear, sliding of the knob manually is required. There is a problem in that the dynamic motion cannot be accurately transmitted to the adjustment shaft of the thermostat.

That is, since the sliding motion of the knob is converted into the rotational motion at the adjustment shaft portion, if the linkage state of the pinion gear and the rack gear varies, the screwing portion of the adjustment shaft with respect to the thermostat body and the pinion gear will not work. Unreasonable stress acts on the screwed part with the rack gear, so if frequent operations are repeated over a long period of time, the temperature of the base changes and it is not possible to adjust the temperature to the optimum temperature for clothes.
