Conveyor belt and drive belt comprising knitted belt, and conveyor device using conveyor belt

A drive belt comprising:

• a seamless knit belt, which is a knit belt forming a drive belt that transmits drive force as a result of engagement between a groove formed in a drive roller and a projecting region at an entangled region of the seamless knit belt is a knit belt comprising knitting yarn containing a plurality of materials;
• monofilament made up of continuous fiber being used at knitting yarn which is filament constituting core yarn;
• being a seamless knit belt comprising knit fabric chosen from among plating using a core yarn and filament of material different from this core yarn for plating thereof;
• knitting knitted using knitting yarn which is twisted yarn in which there is a core yarn and filament of material different from this core yarn for twisting therewith;
• and
• knitting using knitting yarn which is covered yarn in which a core yarn is covered by filament of material different from this core yarn;
• and
• comprising a seamless knit belt in which a front surface of this knit belt and a back surface of this knit belt have different coefficients of friction or a seamless knit belt in which the front surface of the knit belt and the back surface of the knit belt have more or less the same coefficient of friction;
• and
• being comprised of a knit belt having improved force of friction (gripping characteristics) as a result of the fact that filament having higher coefficient of friction than a core yarn has been used as plating yarn to plate the core yarn, has been used as a result of having been included within twisting yarn, or has been used as covering yarn, so as to increase force of friction (gripping characteristics) with respect to a pulley or roller by which drive force is transmitted by a belt and drive pulley or drive roller and said knit belt.
