An engagement chain includes a pair of first and second chain members that are engaged so as to be integrated with each other by moving in an advancing direction and disengaged from each other so as to bifurcate by moving in a retreating direction from the integrated engaged state. A first link plate of the first chain member includes first and second pin holes through which a coupling pin is inserted. A second link plate of the second chain member includes first and second pin holes through which a coupling pin is inserted. A first distance between the first and second pin holes of the first link plate is shorter than a second distance between the first and second pin holes of the second link plate.

Mating chain and movable body transfer device

An elongated object guiding device includes links arranged in series. Adjacent ones of the links are pivotally coupled to each other. An accommodation chamber is defined in the links. Each link includes an inner recess, an inner projection, an outer recess, and an outer projection that limit a pivoting range of the link and an adjacent link so that the links are pivoted between a straight state and a bent state. Each link includes a separating member that separates elongated objects accommodated in the accommodation chamber from each other. Each separating member is pivotally coupled to an adjacent separating member. Each separating member includes a through-hole and a sliding portion that limit a pivoting range of the separating member and an adjacent separating member so that a limit on a first side of the pivoting range is the straight state.

Long object guiding device and partition member

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.
