摘要：A transmission belt includes: an endless annular hoop formed by overlapping aplurality of thin strip-shaped rings; and a multiplicity of elements supported by the hoopin an annularly arranged state along the hoop, the elements including a saddle surface
pressed against an inner circumferential surface of a first ring located at the innermostcircumference of the hoop, the transmission belt wound between a plurality of pulleys totransmit power and having a shape in the width direction of the first ring elasticallydeformed in accordance with the saddle surface in a pressed state while the innercircumferential surface of the first ring is pressed against the saddle surface, wherein thesaddle surface is curved as a whole such that a center portion in the width directionbulges out, and wherein a degree of bulging-out of the center portion is smaller ascompared to a degree of bulging-out of peripheral portions on the both sides, and thefirst ring is formed into a curved shape with a center portion in the width directionbulging out toward the outside in a natural state, and when both side portions in thewidth direction are brought into close contact with the peripheral portions of the saddlesurface in a pressed state, the first ring is turned into a curved shape as a whole such thata center portion in the width direction bulges out in accordance with the shapes of theperipheral portions, and wherein the pressing load against the saddle surface is reducedin the center portion in the width direction or a gap is formed.
