Restraining member, and processing device and conveying device using the restraining member

Abstract

A restraining material includes a frictional surface configured to press against an object to restrain the object and exert a frictional force thereon. The frictional surface is a pattern surface of a base material of the restraining member that will directly contact with the object. The pattern surface includes island-shaped parts separated by a depression and periodically arranged. The depression has a depth of 15 to 50 μm with respect to the frictional surface. A periodic arrangement direction of the island-shaped parts includes a direction defined by that: a pattern index determined by dividing an arrangement pitch of the island-shaped parts in a periodic arrangement direction by the maximum diameter of each island-shaped part in the periodic arrangement direction falls within a range of 1.0 to 100, and the maximum diameter of each island-shaped part in the periodic arrangement direction falls within in a range of 0.1 to 2 mm.
