  • Dial gauge
    Patent number: 6497052
    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).
