Abstract
In a protective frame articulated body, a range of an connection angle between the protective frame body and the adjacent protective frame body is determined such that a plurality of protective frame bodies, being connected in series, through which a body to be protected is passed becomes a shape having a first bent portion, an intermediate linear portion being in a portion closer to a movable-side connection than the first bent portion, a suspending portion hanging from the movable-side connection, and a second bent portion connecting the intermediate linear portion and the suspending portion. In intermediate linear portion, a long-and-short ratio being a value obtained by dividing a long side of a smallest rectangle surrounding the protective frame body viewed from a side by a short side of the smallest rectangle is greater than or equal to a determined intermediate minimum long-and-short ratio.
