PURPOSE:To carry a rubber extruded product stably without deforming by adhering a soft rubber layer having a hollow section penetrating laterally and an abrasion-resistant rubber layer on the outercircumference of a timing belt. CONSTITUTION:The innercircumferential face of an endless timing belt 1 is convex and concave to gear with a timing gear 2 while a soft rubber layer 3 is adhered on the outercircumference. Many pillar hollow sections 4 penetrating laterally are arranged on the soft rubber layer 3. An abrasion-resistant rubber layer 5 is adhered on the outercircumference of the soft rubber layer 3. Since the extention of the timing belt is absorbed by the hollow section 4, it will rotate smoothly. |
