US 2001/0022036 A1 · Dial gauge

Abstract

A dial gauge (1A) has stem bush (20) having a fitting (21) fitted to an inner wall of a stem (5) and having a predetermined clearance between a spindle (3), a holder (22) for slidably holding the spindle (3) while securing a predetermined clearance against the inner wall of the stem (5), and an elastically deformable connector (23) for connecting the fitting (21) and the holder (22), whereby an influence of deformation of the stem (5) and the fitting (21) on the holder (22) during clamping can be minimized, so that the dial gauge (1A) can be fixed to a supporting stand without deteriorating slidability of the spindle (3).

Claims5

Dependent claims

A dial gauge, comprising:

a spindle having a probe to be in contact with a workpiece at a distal end thereof;
a body;
and
a stem provided to the body for slidably holding the spindle through a stem bush, wherein the stem bush has:
a fitting fitted to an inner wall of the stem while securing a predetermined clearance against the spindle;
a holder for slidably holding the spindle, and having a predetermined clearance against the inner wall of the stem;
and an elastically deformable connector for connecting the fitting and the holder, the clearance between the fitting and the spindle being larger than the clearance between the holder and the spindle.
