ABSTRACT:
A pallet exchanger capable of providing a sufficient operation space on an operator's access side, for example, in front of a machining space, without increasing the size of the exchanger is provided. An arm is formed in a chevron shape in a plane view including two forks as pallet supporting parts, which are arranged radially from a turning spindle with less than 180° angle between them such as 120° . Further, by means of a table, the arm is slidable between a stand-by position in front of a machining space and a retreating position laterally separated by a predetermined distance from the stand-by position in a horizontal position. By moving the arm on the retreating position side, an operation space can be provided in front of the machining space.
