Abstract
An inner peripheral surface of a belt is cogged so that cogs extend in a belt width direction and are arranged adjacent to one another at regular intervals in a belt length direction. A tip portion of the cog and a bottom portion of a groove formed between the cogs have curved surfaces each having an arc-shaped cross section. A curvature radius of a cross-sectional shape of the bottom portion of the groove is set to be larger than a curvature radius of a cross-sectional shape of the tip portion of the cog.
