PROBLEM TO BE SOLVED: To adjust an oscillating type conveyance device efficiently by at least an adjustable spring assembly for connecting a base of the conveyance device to a related oscillating trough operably. SOLUTION: This oscillating type conveyance device 10 includes at least one of spring assemblies 20 and 22 for attaching a trough 16 to a base 12 to convey the base 12, the trough 16 and materials within the trough 16. At least one of the spring assemblies 20 and 22 of the device is formed in a manner that it adjusts the spring constant of the assembly selectively. Accordingly, the conveyance device 10 can adjust efficiently to convey a various types of materials by changing the spring constant or the weight ratio of the device using other methods than by changing of a gap of a related electromagnet-oscillating type driving device.
