Claims

[Scope of claim for utility model registration] 1. A rotary knob rotatably provided on the main body frame,
A micrometer having a pinion shaft engaged with the rotation knob and a rack provided on a spindle that is engaged with the pinion shaft and is movable back and forth in the axial direction with respect to the main body frame, wherein the rotation knob and the pinion The rotary knob and the pinion shaft are screwed together so as to be movable in the axial direction, and the rotary knob and pinion shaft are connected to each other via an elastic member so as to act in the shaft rotational direction. A micrometer comprising a constant pressure locking device configured with a contactable contact surface. 2. Claim 1 of the utility model registration claim is characterized in that the locking portion of the elastic member is provided with an adjustment mechanism that is movable relative to the rotary knob so that the spring constant of the elastic member can be adjusted from the outside. micrometer. 3. A micrometer according to claim 1 or 2 of the utility model registration claim, characterized in that a coil spring is used as the elastic member. 4. The micrometer according to claim 1 or 2 of the utility model registration claim, characterized in that a spiral spring is used as the elastic member. 5. A micrometer according to claims 1 and 2 of the utility model registration claim, characterized in that a linear spring is used as the elastic member.
