Abstract: A workpiece holding apparatus includes: a main body; at least one shaft member capable of coming into contact with a workpiece; a clamping device into which the shaft member is inserted, the clamping device being attached to the main body and capable of switching between an unclamping state that releases the shaft member and a clamping state that clamps the shaft member; and a trigger member configured to switch the clamping device between the unclamping state and the clamping state. The trigger member comes into direct contact with the workpiece, or comes into indirect contact with the workpiece via at least a part of the shaft member, thus moving relative to the main body, and the clamping device switches from the unclamping state to the clamping state.
