Summary:PURPOSE:To correctly position a heater by so setting a position of a turning center of a driving pin as to move a contact position of the pin with a long groove longitudinally of the groove between positions at the times of supplying hot air and cold air. CONSTITUTION:A long groove 10 formed on a lever 13 is composed by connecting two long grooves 10a, 10b to a bent part 10c for connecting the grooves 10a, 10b eccentrically located in parallel with each other. The widths of the grooves 10a, 10b are set wider than a diameter of a driving pin 12 to provide a margin for forming a padding 15. The walls of the grooves corresponding to two contact points are so deviated as to be peculiarly formed. Thus, even if the pin 12 is not accurately traced on a rotary locus in design due to any reason, the lever 13 can be accurately positioned at the times of supplying hot and cold airs.
