ABSTRACT:
To provide a cable or the like protection and guide device, which can suppress the sliding contact noise by reliably limiting a linear position and a bending position exhibited during the movement of the cable or the like, and at the same time, which can reduce a setting space by suppressing the impact noise and wear of a connecting pin piece on a connecting pin hole even if the height size of the link body is decreased. A connecting pin piece13, convexly provided on a link body10, which forms a cable or the like protection and guide device, includes stopper surfaces13a, 13a, which are parallel to the upper edge center portion and the lower edge center portion of the side plates11and are oppositely disposed across a bending center point O and a pair of front, and rear arc-shaped outer circumferential surfaces13b, 13b, which are oppositely disposed across the bending center point O. Further a connecting pin hole14, concavely provided in said link body10, includes a pair of linear position maintaining surfaces14a, which are parallel to the upper edge center portion and the lower edge center portion of the side plate10, and are oppositely disposed across the bending center point O, bending position limiting surfaces14b, which are oppositely disposed across the bending center point O in a plane symmetry, and a pair of arc-shaped inner circumferential surfaces14coppositely disposed across said bending center point O in a plane symmetry to be brought into sliding contact with said connecting pin pieces13.
