Claims

[Scope of utility model registration request]

A cylindrical main shaft with a stopper in the center, a main spring surrounding the main shaft and having one end in contact with the stopper, and a main spring slidably fitted onto the main shaft so as to compress the main spring at the end surface. A cylindrical portion extending away from the joined end portion and the main spring, and arranged at approximately equal intervals within the ball holding hole provided around the cylindrical portion.
a first outer sleeve having at least one ball of the same diameter and a ball retaining spring for restricting escape of the balls; a first auxiliary spring provided within the cylindrical portion of the first outer sleeve; The outer surface becomes smaller in diameter as it approaches both ends, and is slidably fitted to the main shaft, and half of the outer sleeve is housed in the cylindrical portion of the first outer sleeve so that one end compresses the first auxiliary spring. A tapered sleeve, a second sub-spring whose one end is in contact with the other end of the tapered sleeve and is provided so as to surround the main shaft, and a compressed second sub-spring and the remaining half of the tapered sleeve are accommodated. A cylindrical part having three or more balls of the same diameter arranged at approximately equal intervals in a ball holding hole provided around the cylindrical part, and a ball holding spring for restricting escape of the balls, and an inner end surface thereof. A deep-hole axial position measuring tool comprising a second outer sleeve having an end in contact with the other end of the second sub-spring and fitted to the main shaft, and a sleeve stopper fixed to the tip of the main shaft.
