ABSTRACT:
A displacement measuring instrument wherein a cam (9) is engaged with a movable member such as a spindle (5), a rectilinear movement of the spindle (5) is converted into a rotary motion of the cam (9), the rotary motion of this cam (9) is enlarged and transmitted to a follower through a rotator (20) rotatable in synchronism with the cam (9), an indicating device (32) is driven due to rotation of the follower (21) for indicating a displacement value of the spindle (5). Component parts are small in number and construction is simplified.
