Abstract
A cup holder is provided, in which a control portion calculates a container-housing-portion temperature gradient ΔT based on a temperature T detected by a thermistor disposed inside a convex portion located on a bottom portion of a container housing portion. The control portion automatically carries out heating or cooling relative to the container housing portion based on that the container-housing-portion temperature gradient ΔT is a heating reference temperature gradient α or above, or is a cooling reference temperature gradient β or below. Thus, determinations of the heating or cooling is carried out based on only the container-housing-portion temperature gradient ΔT, so that heating or cooling control can be accurately carried out only by one temperature sensor.
