Claims

[Scope of Claim for Utility Model Registration] 1. A plurality of driving bodies each having an electrostrictive element attached to the main surface of a leaf spring that also serves as an electrode plate is placed between a carrier and a base, with the upper and lower ends of each What is claimed is: 1. A parts feeder connected to a table, characterized in that at least one of the upper and lower ends of a leaf spring is swingably connected to a mounting portion of a conveyor table or a base via an elastic material. 2. The parts feeder according to claim 1, wherein the elastic material is a disc spring. 3. The parts feeder according to claim 1, wherein the elastic material is a cylindrical spring that elastically contracts in the radial direction of the cylinder. 4. The parts feeder according to claim 1, wherein the elastic material is elastic rubber. 5. The parts feeder according to claim 1, wherein the elastic material is a flexible synthetic resin material. 6. An elastic material is interposed between at least one of the upper and lower ends of the leaf spring and the attachment part of the conveyor table or base, and a connecting screw is inserted loosely into the end part, so that the leaf spring is swingably connected. A parts feeder according to claim 1 of the utility model registration claim characterized by:
