Abstract
A clamping apparatus includes: locking members () insertable into a hole () of a workpiece (); and a clamp rod () configured to make a wedge engagement with the locking members () from above. Each locking member () includes a base portion () configured to be inserted into the hole (); and a protruding portion () located above the base portion (). A relative movement restriction mechanism (M) configured to restrict downward movement of the clamp rod () relative to the locking members () within a predetermined travel distance allows descent of outer peripheral surfaces (a) of the base portions () relative to an inner peripheral surface of the hole () when the locking members () are in a diameter-expanded position.
