Workpiece conveying device including conveying parts having conveying bogies and driving means, and a component feeder

The present invention is a workpiece conveying device, and the issue is to provide a workpiece conveying device which allows a portion of a conveying part to have a processing portion having symmetrical collapse while having a vibration characteristic capable of preventing and suppressing unsatisfactory vibrations which cause interruptions of smooth conveyance during an event of conveyance. The solution includes: conveying parts (1, 3) which are respectively provided with a conveying bogie (1T, 3T), and a drive means (2, 4) for generating a traveling wave in the conveying part (1, 3); a component feeder (X) for conveying a workpiece (W) along the conveying bogie (1T, 3T) through the traveling wave, wherein in the conveying part (1, 3), there are an upper side range (11, 31) including a formed surface of the conveying bogie (1T, 3T) and composed of a low elastic material, and a lower side range (12, 32) located lower than the upper side range and composed of a high elastic material, the elastic rate of which i
