     Claim: 
      
 AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT: 
The patentability  of claims 1-7 is  confirmed. 1. A clamping 
apparatus with datum function which aligns a movable member (M) 
with a reference member (R) and fixes a surface (T) to be 
supported of the movable member (M) to a support surface (S) of 
the reference member (R),the clamping apparatus comprising: a 
socket  bore (11) formed  in the movable member (M), the socket 
bore (11) being provided with an opened end formed by opening the 
surface (T) to be supported and having a positioning hole (12) and 
an engaging hole (13) formed in order from the opened end; an 
annular plug portion (21) having a cylindrical hole(21a) and 
projecting from the reference member (R) so as to be inserted
into the socket bore (11); a shuttle member (23) having a tapered 
surface(28), which is arranged between the plug portion (21) and 
the positioning hole (12) and diametrically expands and contracts, 
the shuttle member (23)being supported by one of the plug portion 
(21) and the positioning hole(12) so as to be axially movable 
within a predetermined range and making a tapering engagement with 
the other, the tapered surface (28) for the tapering engagement 
being-formed so as to narrow toward the engaging hole(13); a 
resilient member (24) urging the shuttle member (23) in a direction
for tightening the tapering engagement; a pull rod (31) having a 
first end, a second end and an output portion (36), the pull rod 
(31) being axially movably inserted into the cylindrical hole (21a) 
of the plug portion (21); an engaging member (34) arranged in an 
outer peripheral space of the pull rod (31) and being movable 
between a radially outward engaging position (X)and a radially 
inward disengaging position (Y); a driving means (D) provided in 
the reference member (R) and connected to the pull rod (31);
and the driving means (D) driving the pull rod (31) for clamping 
in a direction toward the first end, thereby enabling the output 
portion (36)of the pull rod (31) to switch over the engaging 
member(34)to the engaging position (X) for engaging it with the 
engaging hole (13) to move the movable member (M) toward the 
reference member(R), the driving means (D)driving the pull rod 
(31)for unclamping in a direction toward the  second end, thereby 
allowing the engaging member (34) to switch over to the 
disengaging position (C).
