Patent ID: 7213700

Claim:
A part carriage device for applying vibration generated at a vibration body to a part and linearly conveying the part, comprising: a base part which is disposed at a lowest side of the part carriage device; a first drive part which is arranged above the base part through a vibration prevention member; a weight part which is arranged above the first drive part through a support member and the vibration body; a second drive part which is arranged above the weight part through a connection member connected to the first drive part; and a carriage way which is arranged above the second drive part and conveys the part in a horizontal direction, wherein a straight line for connecting a total barycentric position, which is a sum of a barycentric position of the first drive part, a barycentric position of the second drive part, and a barycentric position of the carriage way, with a barycentric position of the weight part is approximately in parallel to an angle for applying the vibration to the part.
