Abstract
A moving handrail superior in durability includes a linear belt of which two end portions are connected, forming a loop. This linear belt includes a single-layer or multilayer of thermoplastic elastomer having a C-shape in cross section; metallic and web-shaped metal stretch inhibitors disposed along a longitudinal direction of the thermoplastic elastomer, and base members coupled inside of the thermoplastic elastomer. The thermoplastic elastomer, metal stretch inhibitor, and base member are integrally molded. In the connection portion, a splice junction between the metal stretch inhibitors and a joint where the base members are connected together at both end portions with an auxiliary backing does not overlap in a direction of thickness of the moving handrail. Further, the metal stretch inhibitors that are spliced are enclosed with a thermoplastic elastomer.
