摘要

PROBLEM TO BE SOLVED: To provide a toothed belt reinforcing sheet capable of being easily manufactured to form a toothed belt with a toothed portion to be less broken in long time use, and to provide the toothed belt using the toothed belt reinforcing sheet and its manufacturing method.

SOLUTION: The toothed belt reinforcing sheet comprises a fiber sheet and a coating formed on the fiber sheet. The coating is formed by applying water-based treatment agent containing first rubber latex and vulcanizing agent as the main constituent to the fiber sheet and drying it.
