PROBLEM TO BE SOLVED: To provide a synchronous belt capable of suppressing sagging deformation of a belt to a back side in a region where belt tension decreases, to thereby prevent occurrence of tooth jumping, and provide a belt transmission device, an electric steering device, a synchronous belt manufacturing method and a synchronous belt manufacturing device.SOLUTION: A synchronous belt has: an annular core wire; and belt side internal teeth meshed with a pulley side external teeth provided on each of two pulleys, and provided on a radial inward side with respect to the core wire, and is wound around the two pulleys. An outer peripheral side portion to the core wire in winding around the two pulleys is a portion to which tensile residual stress is imparted in a circumferential direction. Also, an inter peripheral side portion to the core wire in winding is a portion to which compression residual stress is imparted in the circumferential direction.SELECTED DRAWING: Figure 10

    【課題】ベルト張力が減少する領域でベルトの背面側への弛み変形を抑えることで、歯飛びを発生し難くすることが可能な歯付きベルト、ベルト伝達装置、電動ステアリング装置、歯付きベルト製造方法、及び歯付きベルト製造装置を提供する。【解決手段】歯付きベルトは、環状の心線と、2個のプーリそれぞれに設けられたプーリ側外歯に噛合する、心線に対して径方向内側に設けられたベルト側内歯と、を有しており、2個のプーリに巻き掛けられる。2個のプーリへの巻き掛け時における心線に対する外周側部位は、周方向に引張残留応力が付与されている部位である。また、巻き掛け時における心線に対する内周側部位は、周方向に圧縮残留応力が付与されている部位である。【選択図】図10
