PROBLEM TO BE SOLVED: To provide a continuous heat treatment device capable of remarkably reducing its heat treatment time and inhibiting the generation of distortion, with respect to the heat treatment device suitably used for aluminum vehicle parts, in particular, a light alloy wheel having a large diameter of more than 16 inches. SOLUTION: This continuous heat treatment device for aluminum vehicle parts comprises a conveying means for conveying the aluminum vehicle parts inside, and an air blasting means capable of controlling a wind speed of the furnace atmosphere to be 15 m/s or more, a temperature rise time to a solution treatment temperature of the aluminum vehicle parts is within 30 minutes, and a control width of a work temperature after the temperature rise can be controlled to a target temperature±2°C or less.
