Zusammenfassung:	A broaching device is provided with puller heads (132,134) that hold tip portions of broaches (116) and are supported in a horizontally freely movable manner, main motors (136, 140) capable of moving the puller heads (132, 134), retriever heads (133,135) that hold base end portions of the broaches (116) and are supported in a horizontally freely movable manner, sub motors (138,142) capable of moving the retriever heads (133,135), and a control device (117) that enables the puller heads (132,134) and the retriever heads (133, 135) to be synchronized with each other and to move at a fixed speed by controlling the motors (136,138,140,142), whereby machining accuracy can be improved.
