Abstract: A chain bending limiting attachment includes first bending limiting members and second bending limiting members. The first and second bending limiting members are detachably attached to a chain to be arranged in a series arrangement direction. Each first bending limiting member includes a first engaging portion. When the chain bends in a first direction, the first engaging portion engages with another first bending limiting member adjacent to the first bending limiting member in the series arrangement direction to limit bending of the chain in the first direction. Each second bending limiting member includes a second engaging portion. When the chain bends in a second direction, the second engaging portion engages with another second bending limiting member adjacent to the second bending limiting member in the series direction to limit bending of the chain in the second direction.
