摘要： PROBLEM TO BE SOLVED: To obtain a large cutting powder with a simple constitution and a small feeding powder by forming asymmetrical recesses on a driving link disposed at an intermediate part of two coupling links. SOLUTION: A recess 18 and a deepest part of the recess at a transfer part 17c between a preceding edge 17a and a trailing edge 17b are disposed at positions for passing a central vertical line 19 of a connecting line 20 to be assumed between central points 21 of rivet holes 8, 9 in a feeding direction 7 or positions before the line 19. The edges 17a, 17b are rounded at different radii R2, R1. The edge 17a having the smaller radius R2 is disposed before the direction 7 of a chain, and the edges 17a, 17b are connected to one another with one roundness. The deepest part formed at the part 17c between the edges 17a and 17b is disposed in a cutting groove formed between a driving link 2 and a roof surface. Thus, the preceding edge having the larger radius is rounded in a protrusion manner so that cutting chips can be discharged without clogging.

摘要： PROBLEM TO BE SOLVED: To obtain strong flexural strength, compressive strength, and torsional strength by applying initial stress distributed uniformly in the plane of a guide rail by the close engagement of a relatively light cured material part with the fringe part of an opening with the guide rail free from a load. SOLUTION: In order to give strong torsional rigidity to a steel plate 4 or a guide rail, the opening is filled with a relatively light material, especially a synthetic resin. The material approximately 0.5-1% or more in coefficient of contraction is cast or injected into the opening until it is filled completely. Since a synthetic resin part 19 is inserted into the undercut of 12 of an opening fringe part shape-supplementarily in the plane of a substrate 4, the tension applied by the contraction of the resin during curing is transmitted surely to the steel plate 4.
