摘要： An inside diameter measuring tool includes: a main body; an axially moving spindle having a male screw to be screwed to the main body; a plurality of contact pieces provided on the main body, the measuring pieces moving in a direction substantially orthogonal to the axial direction of the spindle; and a conical member interposed between the contact pieces and the spindle, the conical member advancing and retracting the contact pieces in the direction substantially orthogonal to the axial direction of the spindle. The lead of the male screw of the spindle is 1.0 mm or more and the cone angle of the conical member is less than 53 degrees. Preferably, the lead of the male screw is 2.0 mm and the cone angle of the conical member is approximately 28 degrees.

摘要： A digital displacement measuring instrument includes a spindle screwed into a body to be axially advanced and retracted relative to the body; and an encoder that detects a displacement of the spindle. The encoder includes a rotor and a stator. The rotor is supported by a rotor bushing. The rotor bushing includes an engaging key engageable with a key groove axially provided on the outer circumference of the spindle, and is displaceable in the axial direction of the spindle via a position adjusting screw. The stator is fixed to the body via a stator bushing in the vicinity of the spindle so as not to be displaceable in the axial direction of the spindle.

摘要： A digital displacement measuring instrument detects a displacement of a spindle by an encoder and then displays the displacement on a digital display unit. With an imaginary base line centered along an axial direction of an outer circumference of a sleeve, a millimeter graduation for displaying the displacement of the spindle in millimeters is provided on one side, and the inch graduation for displaying the displacement of the spindle is provided on the other side.

摘要： A micrometer includes: a body; a fixed sleeve that is fixed to the body; a spindle that is screwed to the fixed sleeve; a thimble that is rotatably fitted to an outer circumference of the fixed sleeve and has an outer end connected to the spindle; an operation sleeve fitted over a range from an outer circumference of the thimble to an outer end of the spindle and being rotatable relative to the thimble; and a constant pressure mechanism that is disposed between the operation sleeve and the spindle, the constant pressure mechanism transmitting a rotation of the operation sleeve to the spindle and allowing a free rotation of the operation sleeve against the spindle when a predetermined or more amount of load is applied on the spindle. Ball bearings are disposed between the thimble and the operation sleeve.
