A tool changer, used for exchanging tools between a tool magazine and a tool spindle of a machine tool, includes a tool-changing unit and a feed screw. The tool-changing unit has a rotating shaft with a changing arm attached to one end thereof and a rotating drive motor attached to the other end thereof. The feed screw has one end to which a drive motor is attached to cause the tool-changing unit to perform a feed operation of a tool and also perform detachment/attachment of the tool by utilizing the feed operation. Additionally, the feed screw is parallel to a rotational axis of the tool spindle positioned at a tool-changing position.
