PURPOSE: An air supply duct of a drier is provided to uniform temperature of air supplied through the air supply duct into a drying chamber. CONSTITUTION: A channel(32) is formed in a duct main body(31) of an air duct(30) for hot air to flow therein. The duct main body has a middle part whose section is square and comprises a front surface(31f) facing a rear end of a drum, a rear surface(31r) facing the front side and side surfaces(31s) connecting the front surface and the rear surfaces. An inlet(33) is formed on a lower end of the duct main body to be fluidically connected with a hot blast duct. An outlet(34) is formed on an upper end of the duct main body to be fluidically connected with a drying chamber in the drum. A front suction part(40) is formed on the front surface to introduce relatively low temperature air in the outside into the channel. Central suction ports(42) and end suction ports(43) are alternately formed on the front suction part correspondingly with the middle and both ends of the front surface. Side suction parts and rear suction part are formed on the side surfaces and the rear surface, respectively.
