<P>PROBLEM TO BE SOLVED: To provide an engagement chain unit configured such that chains are reliably and firmly engaged with each other and that the buckling and twisting of a rigidified chain portion are avoided. <P>SOLUTION: The engagement chain unit 100 is configured such that the outer edge of a plate overlap region P is defined by contact portion surfaces 111aa, 111aa and flat buckling regulating end surfaces 112b, 112b and the plate overlap region P is constituted from contours of two plate superimposing parts Pa, Pa which are point-symmetric to each other about the intersection point C between hook-shaped engagement end surfaces 111a, 111a and the buckling regulating end surfaces 112b, 112b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
