Strain gauges are disposed at the intersections of the straight line extending through the origin O with the diaphragms 15 and 16.

Abstract: In a tension measuring apparatus, two fixed electrodes (11, 12) are distantly arranged on a single plane, and a movable electrode (32) is disposed parallel to the fixed electrodes to face the fixed electrodes. When a fiber (A) is pressed onto a force receiving portion (70), the movable electrode (32) is rotated around a rotational axis (33P). This changes the distances of the movable electrode (32) from the fixed electrodes (11, 12). The force received by the force receiving portion (70) from the fiber (A) is measured based on changes in the capacitance values of the capacitance elements (C11, C12) constituted by the movable electrode (32) and the respective fixed electrodes (11, 12).
