Abstract
An air-conditioner has a heater core in an air passage. A bypass passage is formed within the air passage and at a side portion of the heater core. A holding shaft is pivotally disposed at the boundary between an air-flow through the heater core and an air-flow through the bypass passage. A sliding shaft is disposed upstream of the heater core and slides to cross a substantially whole area of the air passage. A first end and second end of a variable length damper which varies its length are connected to the sliding shaft and the holding shaft respectively so that the variable length damper moves in such a manner that its length varies in response to a distance between the sliding shaft and the holding shaft.
