<p>The clamping apparatus (10) has an elbow-shaped portion provided along radially outward direction of a spring element that is coupled to a sliding block (18). A step-shaped recess is formed in a counter-holder so as to exert axial force on the spring element. The elbow-shaped portion is held in a pre-tensioned assembled position in axial direction, at first stage of the recess. The elbow-shaped portion is held in a locking position by partial relaxation of spring element along the recess in circumferential direction corresponding to the second stage of the recess.</p> |
