Micrometer that holds displayed displacement when retraction amount is less than a set amount
 A minimum value renewal holder (33) for renewing and displaying a detected value (D) detected by a displacement sensor (9) on a display (10) when a spindle is moving in an advancing direction relative to an anvil and for holding a displayed value on the display (10) when the spindle moves in a retracting direction relative to the anvil and a retraction amount thereof (D-Dm) is less than a set amount (.alpha.), and a minimum value hold releasing potion (34) for releasing minimum value hold status when the spindle moves in the retracting direction relative to the anvil and the retraction amount (D-Dm) is not less than the set amount (.alpha.) are provided. Accordingly, the displayed value can be kept even when the anvil backs unpreparedly.
