Abstract
A clamp sensor includes: a pair of clamp arms that construct a ring-shaped sensor in a closed state and rotate about a rotational shaft provided near base ends of the clamp arms so that other ends of the clamp arms come in to contact and move apart; and a pair of operating arms that extend from the base ends of the clamp arms and are capable, by rotating about the rotational shaft so as to approach each other, of shifting the clamp arms into an open state. The operating arms are formed in arc shapes where, when looking along an axial direction of the rotational shaft, an outer edge of one operating arm and an outer edge of the other operating arm are curved in a same direction.
