A tool changing device for detaching a previously-used tool as one of a plurality of tools from a spindle of a machine tool and attaching a subsequently-used tool as a tool different from the previously-used tool to the spindle, the tool changing device comprising:

• a magazine including a rotatable magazine body and a plurality of tool pots attached to the magazine body, the plurality of tools being respectively attachable to the plurality of tool pots, one of the plurality of tool pots being disposed at an change position by rotation of the magazine body;
• an arm including a first grip member and a second grip member, the first grip member and the second grip member each being rotatable around a direction orthogonal to an axial length direction of the spindle, the arm being configured, by one of the first grip member or the second grip member, to detach the subsequently-used tool from the tool pot disposed at the change position and attach the subsequently-used tool to the spindle and, by one other of the first grip member or the second grip member, to detach the previously-used tool from the spindle and attach the previously-used tool to the tool pot disposed at the change position, and
• a grip interlocking mechanism that rotates a grip member on the magazine side of the first gripping member and the second gripping member in conjunction with a movement of the arm relative to the magazine to grip and release gripping of the tool, and rotates a grip member on the spindle side of the first gripping member and the second gripping member in conjunction with a movement of the arm relative to the spindle to grip and release gripping of the tool.
