PROBLEM TO BE SOLVED: To provide a work feeder capable of reducing the size, the weight and the manufacturing cost of a feeder body even when an unclamping electromagnet is provided. SOLUTION: A movable plate is elastically supported by an elastic member with respect to a second fixed plate, a working plate is magnetically attracted by the excitation of an unclamping electromagnet, the movable plate is moved against the elastic force of the elastic member, and a space of the size in which a workpiece can be inserted is formed between a press roll and a drive roll.
